openAAL - the open source middleware for ambient-assisted living (AAL)
In: AALIANCE conference, Malaga, Spain, March 11-12, 2010, 2010
Abstract openAAL is a joint open source initiative by FZI Research Center for Information Technologies, Friedrich-Schiller-University of Jena and CAS Software AG. It represents a flexible and powerful middleware for ambient-assisted living (AAL) scenarios and is based on research results of several German and international projects including the SOPRANO Integrated Project. The openAAL platform enables easy implementation, configuration and situation-dependent provision of flexible, context-aware and personalized IT services.

Knowledge Maturing Activities and Practices Fostering Organisational Learning: Results of an Empirical Study
In: Fifth European Conference on Technology-Enhanced Learning (ECTEL 2010), Barcelona, Spain, Springer, 2010
Abstract Knowledge work is performed in all occupations and across all industries. The level of similarity of knowledge work allows for designing supporting tools that can be widely used. In this paper an activity-based perspective towards knowledge work is taken. Based on findings from a previous ethnographically-informed study, we identified valuable activities to be supported in order to increase knowledge maturing inside companies. The goal of this paper is to contribute to which knowledge maturing activities are deemed important, so that they can be supported by IT services. Quantitative and qualitative data have been collected in 126 organisations of different size, sector and knowledge intensity. Important feedback and issues emerged and need to be managed in order to support success in the knowledge maturing activities that allow improvement of organisational learning through the dissemination and application of the most appropriate knowledge.

SOPRANO Ambient Middleware: Eine offene, flexible und markt-orientierte semantische Diensteplattform für Ambient Assisted Living
In: 2. Deutscher Kongress Ambient Assisted Living, Berlin, Januar 2009, VDE Verlag, 2009
Abstract Das Europäische Integrierende Projekt SOPRANO zielt auf die Schaffung einer offenen Plattform für Ambient-Assisted-Living-Lösungen, die älteren Menschen länger ein unabhängiges selbstbestimmtes Leben im eigenen Zuhause ermögli-chen sollen. Um solche Lösungen markttauglich zu machen, ist es von herausragender Bedeutung, sie durch einen fle-xiblen Aufbau anpassbar an die jeweiligen Bedürfnisse zu gestalten und eine funktionierende Marktökologie zu schaf-fen, bei der nicht ein einziger Anbieter alle Funktionen und Dienste entwickelt/betreibt, sondern unterschiedliche Akteure mit ihren jeweiligen Stärken zusammenwirken können. Dazu wird eine technische Plattform konzipiert, die es ihnen ermöglicht ihre Dienste, Produkte und Erfahrungen zu integrieren. Doch eine rein technisch verstandene Modularität reicht nicht aus, um in einer komplexen Domäne wie AAL ein reibungsarmes Zusammenspiel von unabhängig vonei-nander entwickelten Systemteilen zu gewährleisten. Hierzu werden Methoden zur Sicherung der semantischen Kohärenz benötigt, die in SOPRANO durch einen ontologiegestützten Architekturansatz und semantische Verträge zwischen den einzelnen Komponenten umgesetzt werden.

Applying Semantic Technologies for Context-Aware AAL Services: What we can learn from SOPRANO
In: Workshop on Applications of Semantic Technologies 09, Informatik 2009, Lecture Notes in Informatics vol. , GI, 2009
Abstract Ambient assisted living (AAL) is a newly emerging term describing a research area with focus on services that support people in their daily life with particular focus on elderly people. This includes reminding and alerting the assisted person(s) and their environment, giving feedback, advice, and impulses for physical, or social activities, among others. All of these supportive actions need to be context-aware. Semantic technologies have been considered to be a perfect fit for context-awareness in pervasive computing and ambient intelligence. Mainstream semantic (web) technologies are nowadays largely based on description logics and the W3C standard OWL-DL, which are also used in the AAL domain (see [PG07] and [KC06]). The analysis of the scenarios and use cases, however, have yielded requirements and constraints, which have shown that these mainstream technologies are not well-suited for the AAL domain. In this paper we present the SOPRANO approach as an alternative semantic approach to capturing, managing, and enriching context information for context-aware AAL services.

Integrating Motivational Aspects into the Design of Informal Learning Support in Organizations
In: 9th International Conference on Knowledge Management and Knowledge Technologies, September 2-4, 2009, Graz, Austria, 2009, pp. 259-267
Abstract Motivational aspects in knowledge management have so far largely been considered from the perspective of designing and implementing incentives that influence the extrinsic motivation of employees to participate, contribute, share etc. This is increasingly considered problematic so that this contribution takes a more holistic viewpoint by analyzing and systematizing barriers that have an impact on the motivation to engage in knowledge maturing activities. Based on an ethnographic study and targeted semi-structured interviews, a model is presented that decomposes the motivational aspects. Furthermore, it is presented how motivational aspects can be incorporated into the design of learning support systems.

Mit “People Tagging” zum Kollaborativen Kompetenzmanagement
In: Isabella Peters and Cornelius Puschmann and Violeta Trkulja and Katrin Weller (eds.): SoSoft 09 - Social Software @ Work. Collaborative Work, Communication and Knowledge Management in Theory and Practice. Proceedings of the 1st Interdisciplinary Workshop of the Heinrich-Heine-University Düsseldorf, Germany, September 28th and 29th, 2009, CEUR Workshop Proceedings vol. 591, 2009, pp. 65-71
Abstract Das Wissen darüber, wer was weiß, ist im Unternehmen ein essentielles Element für effiziente Wissensreifungsprozesse, wie etwa das Finden des richtigen Ansprechpartners. Viele Ansätze, die dies adressieren, konnten ihren Versprechungen jedoch nicht gerecht werden. Häufig weil in den Verzeichnissen enthaltene Informationen schnell veraltet oder nicht in einer für die Nutzer relevanten Weise beschrieben waren. Zur Überwindung dieser Probleme präsentieren wir einen Ansatz zum kollaborativen Kompetenzmanagement, der alle Mitarbeiter einbindet und teilnehmen lässt. Die Basis hierfür bildet das sog. "People Tagging", bei dem jeder Mitarbeiter die Expertise und Interessen seiner Kollegen mit Tags beschreiben kann. Dies wird durch Methoden der Community-gestützten Ontologieentwicklung ergänzt, mit denen Mitarbeiter den zum Tagging verwendeten Kompetenzkatalog ständig weiterentwickeln und ihren Bedürfnissen anpassen.

Using the Ontology Maturing Process Model for Searching, Managing and Retrieving Resources with Semantic Technologies
In: OnTheMove Federated Conferences 2008 (DAO, COOP, GADA, ODBASE), Monterrey, Mexico, Lecture Notes in Computer Science vol. , Springer, 2008
Abstract Semantic technologies are very helpful in improving existing systems for searching, managing and retrieving of resources, e.g. image search, bookmarking or expert finder systems. They enhance these systems through background knowledge stored in ontologies. However, in most cases, resources in these systems change very fast. In consequence, they require a dynamic and agile change of underlying ontologies. Also, the formality of these ontologies must fit the users needs and capabilities and must be appropriate and usable. Therefore, a continuous, collaborative and work or task integrated development of these ontologies is required. In this paper, we present how these requirements occur in real world applications and how they are solved and implemented using our Ontology Maturing Process Model.

Ontologies, Dialogue and Knowledge Maturing: Towards a Mashup and Design Study
In: Andreas Schmidt and Graham Attwell and Simone Braun and Stefanie Lindstaedt and Ronald Maiaer and Eric Ras (eds.): 1st International Workshop on Learning in Enterprise 2.0 and Beyond, CEUR Workshop Proceedings vol. 383, 2008
Abstract This paper proposes an initial design study to examine and test some of the key concepts and issues within a large-scale European research project that is exploring and aiming to realise learning as a process of knowledge maturing in the workplace. It will outline some of these concepts, based on a contemporary (or Web 2.0 driven) articulation of how ontologies can be acquired, externalised and exploited by a user-community and introduce a new role for learning dialogue - through developing work into „dialogue games‟. An initial scenario, or „thought experiment‟, is proposed that is grounded on currently available ontology development (SOBOLEO) and learning dialogue (InterLoc) web-technologies and how these could be integrated, or „mashed up‟, to improve the management, understanding and application of labour market information in the context of careers advice. Finally, we also consider the potential role of m-learning techniques and the implications about context that these give rise to.

Partizipative Entwicklung von Kompetenzontologien
In: Workshop Nutzerinteraktion im Social Semantic Web, Mensch & Computer - 8. Fachuebergreifende Konferenz - M&C 2008 (Sept. 8-9, 2008, Lübeck, Germany), 2008
Abstract Ontologiebasierte Ansätze haben sich im Bereich des Kompetenzmanagments, z.B. für die Zusammenstellung von Teams, als vielversprechend herausgestellt. Mit dem Modell des Ontologiereifungsprozesses präsentieren wir einen partizipativen Ansatz für die Entwicklung von Kompetenzontologien, der alle Mitarbeiter in einer Organisation miteinbindet. Dadurch können übliche Probleme in der Erstellung und Pflege der Kompetenzontologie, wie fehlende Aktualität oder unterschiedliche Granularität, aber auch der individuellen Kompetenzprofile überwunden werden. Zur Unterstützung des Ontologiereifungsprozesses für das Kompetenzmanagment wurde die AJAX-basierte semantische Social-Bookmarking-Anwendung SOBOLEO entwickelt, welche die aufgaben-integrierte Entwicklung von Kompetenzontologien zusammen mit einem einfach zu nutzenden Interface bietet.

Conceptual Foundations for a Service-Oriented Knowledge & Learning Architecture: Supporting Content, Process, and Ontology Maturing
In: 8th International Conference on Knowledge Management (I-KNOW 08), Graz, 2008
Abstract The knowledge maturing model views learning activities as embedded into, interwoven with, and even indistinguishable from everyday work processes. Learning is understood as an inherently social and collaborative activity. The Knowledge Maturing Process Model structures this process into five phases: expressing ideas, distributing in communities, formalizing, ad-hoc learning and standardization. It is applicable not only for content but also to process knowledge and semantics. In the MATURE IP two toolsets will be develop that support the maturing process: a personal learning environment and an organisation learning environment integrating the levels of individuals, communities and organisation. The development is guided by the SER theory of seeding, evolutionary growth and reseeding and is based on generally applicable maturing services.

SOPRANO - An extensible, open AAL platform for elderly people based on semantical contracts
In: 3rd Workshop on Artificial Intelligence Techniques for Ambient Intelligence (AITAmI’08), 18th European Conference on Artificial Intelligence (ECAI 08), Patras, Greece, 2008
Abstract Several initiatives have shown the potentials of applying AI techniques to ambient intelligence in general and ambient assisted living in particular. While these systems succeed in adding “intelligence” to systems, they do not provide the extensibility and openness of products ready for the market. In this paper, we present the SOPRANO approach, which is based on a combination of ontologybased techniques and a service-oriented device architecture. In this approach, we focus on separating different aspects of the system like sensors & actuators, context information, and system behaviour, and provide a framework that clearly defines contracts for different solution contributors utilising semantic technologies.

Adaptive Reading Assistance for the Inclusion of Learners with Dyslexia
In: IEEE Conference on Advanced Learning Technologies (ICALT 08), 2008
Abstract Dyslexia is a major barrier to success in education and later on the job as reading skills are fundamental for personal competence development. Children with dyslexia have special learning needs (e.g., more teacher support), which currently only specialized institutions can provide. However, this takes children out of their peer group and causes social problems. On the other side, there is general-purpose reading support software, which is not geared towards children with dyslexia as they lack personalization. AGENT-DYSL brings together speech and image recognition as well as semantic technologies to build a truly adaptive reading support system for children with dyslexia.

People Tagging & Ontology Maturing: Towards Collaborative Competence Management
In: 8th International Conference on the Design of Cooperative Systems (COOP '08), Carry-le-Rouet, France, May 20-23, 2008, 2008
Abstract Competence Management approaches, aiming at making transparent individual competencies and their relationship to organizational goals, suggest promising instruments for more effective resource allocation, knowledge management, learning support, and human resource development in general. However, especially on the level of individual employees, such approaches have so far not been able to show sustainable success on a larger scale. Piloting applications like expert finders have often failed in the long run because of incomplete and outdated data, apart from social and organizational barriers. This affects both competency profiles of the individual employee and non-adequate and often also outdated competency catalogs used as a vocabulary for the profiles. To overcome these problems, we propose a collaborative competence management approach. In this approach, we combine Web 2.0-style bottom-up processes with organizational top-down processes: Web 2.0 oriented bottom-up processes allow every employee to participate and contribute with low usage barriers; i.e. by tagging colleagues; the organizational processes take up and guide these bottom-up developments towards organizational goals. Key idea is that we cannot do competence management completely without an agreed vocabulary (or ontology), i.e. the competency catalog, but we have to make the process of evolving this catalog more collaborative and embedded into its actual usage (e.g., while tagging other employees). Likewise, we do not conceive competency profiles as self-descriptions, but rather as results of collective judgments of others. We approached this problem as a collaborative ontology construction problem of which the conceptual foundation is the Ontology Maturing Process Model. In order to realize the Ontology Maturing Process Model for competence management, we have built the AJAX-based semantic social bookmarking application SOBOLEO that offers task-embedded competence ontology development and an easy-to-use interface.

Kontextsensitive Technologien und intelligente Sensorik für Ambient-Assisted-Living-Anwendungen
In: 1. Deutscher Kongress Ambient Assisted Living (AAL 2008), VDE Verlag, 2008
Abstract Die Realisierung von AAL-Szenarien ist technologisch sehr aufwändig: Einerseits werden für die Erfassung von physikalischen Signalen eingebettete Sensoren und hardwarenahe Software-Funktionen benötigt, andererseits müssen Kontext-Informationen auf einer viel höheren Abstraktionsebene modelliert und interpretiert und über geeignete Mechanismen verschiedenen Anwendungen zur Verfügung gestellt werden. Für die Realisierung von AAL-Szenarien müssen diese Ergebnisse nun nahtlos integriert und zu nutzbaren Anwendungen umgesetzt wer-den. Im Beitrag wird beschrieben, wie verschiedene Technologien und Ansätze am FZI im interdisziplinären Forschungsfeld "Kontextsensitive Dienste und Intelligente Umgebungen" integriert werden und so neue For-schungsperspektiven für Ambient Assisted Living Anwendungen eröffnen.

Mind the Web!
In: Ruzica Piskac and Frank van Harmelen and Ning Zhong (eds.): New Forms of Reasoning for the Semantic Web: Scalable, Tolerant and Dynamic 2007. Proceedings of the First International Workshop, ISWC 2007, Busan, Korea, November 11, 2007, CEUR Workshop Proceedings vol. 291, 2007
Abstract This paper argues that a significant part of today’s Semantic Web research is still dominated by ideas from centralized databases. Furthermore, the main thread of reasoning research focusses on approaches that can never scale to anything similar to the Web. Starting from these negative observations we argue that emergent semantics and ontology maturing are more suitable approaches for dealing with ontologies on the Web. Similarly, a few approaches for more Semantic Web appropriate reasoning exist, but are in dire need of realistic use cases.

Ontology Maturing with Lightweight Collaborative Ontology Editing Tools
In: Norbert Gronau (eds.): 4th Conference on Professional Knowledge Management - Experiences and Visions, Workshop on Productive Knowledge Work (ProKW 07), GITO, 2007, pp. 217-226
Abstract Ontology building is an important prerequisite for state-of-the-art semantic technologies for knowledge worker support. But ontology engineering methods have so far neglected the early phase of ontology building where a conceptualization only exists rather informally and underlies continuous evolution through collaboration and interaction within the community. We have to view ontology building as a maturing process that requires collaborative editing support and the integration into the daily work processes of knowledge workers. In spirit of current Web 2.0 applications, we present an AJAX-based lightweight ontology editor as a first approach to this problem.

Im Wissensnetz: Linked Information Processes in Research Networks
In: Proceedings of the German e-Science Conference 2007 (GES 2007), Baden-Baden, Germany, 2007
Abstract At first glance, it seems to be quite surprising that so far traditional business process-oriented knowledge management techniques have not been transferred to research in order to improve the efficiency of scientific work on a larger scale. But due to the high variability and unpredictability of scientific work processes, these techniques are not applicable. In fact scientific work processes have to be understood as a network of informal learning processes with a high level of social in-teraction. For this purpose, we have elaborated the model of a “Knowledge-Added Process” as a new paradigm of process-oriented support. We are developing various models, methods, and tools on the basis of semantic technologies supporting this process, and which are exemplified within three scenarios within the application domain “rapid prototyping”.

The Ontology Maturing Approach to Collaborative and Work-Integrated Ontology Development: Evaluation Results and Future Directions
In: Luke Liming Chen and Philippe Cudré-Mauroux and Peter Haase and Andreas Hotho and Ernie Ong (eds.): Emergent Semantics and Ontology Evolution 2007. Proceedings of the First International Workshop on Emergent Semantics and Ontology Evolution (ESOE-2007), ISWC 2007, Busan, Korea, November 12, 2007., CEUR Workshop Proceedings vol. 292, 2007, pp. 5-18
Abstract Ontology maturing as a conceptual process model is based on the assumption that ontology engineering is a continuous collaborative and informal learning process and always embedded in tasks that make use of the ontology to be developed. For supporting ontology maturing, we need lightweight and easy-to-use tools integrating usage and construction processes of ontologies. Within two applications – ImageNotion for semantic annotation of images and SOBOLEO for semantically enriched social bookmarking – we have shown that such ontology maturing support is feasible with the help of Web 2.0 technologies. In this paper, we want to present the conclusions from two evaluation sessions with end users and summarize requirements for further development.

Sustainable Competency-Oriented Human Resource Development with Ontology-Based Competency Catalogs
In: Miriam Cunningham and Paul Cunningham (eds.): Expanding the Knowledge Economy: Issues, Applications, Case Studies. Proceedings of E-Challenges 2007, IOS Press, 2007
Abstract Competency-oriented approaches are gaining ground in human resource development. Key technology to cope with the complexity of fine-grained approaches are ontologies. By having a formal semantics, many competency-related task can be partially automated on a technical level. In this paper, we want to show that ontology-based approaches also foster the sustainability of such approaches on an organizational level by providing connections between the operational and strategic level. We present a reference ontology and a reference process model which have been applied in a hospital case study.

AGENT-DYSL: A Novel Intelligent Reading System for Dyslexic Learners
In: Miriam Cunningham and Paul Cunningham (eds.): Expanding the Knowledge Economy: Issues, Applications, Case Studies. Proceedings of E-Challenges 2007, IOS Press, 2007
Abstract In this paper we present a novel approach for facilitating dyslexic children in learning to read fluently. We explain the motivation, general idea and initial results in terms of user requirements and system architecture. Unlike previously presented approaches, the aim of this system is to monitor the progress and perspectives of a dyslexic user and supply personalised help, taking advantage of modern ICT features. The goal of this personalised help is to gradually increase the reading capabilities of the user, gradually diminish the assistance provided, till he is able to read as a non-dyslexic learner.

Adaptive Reading Assistance for Dyslexic Students: Closing the Loop
In: 15th Workshop on Adaptivity and User Modeling in Interactive Systems, LWA 2007, Halle, 2007
Abstract Adaptive reading assistance can improve the reading performance of students, but current dyslexia pedagogical theories do not yet provide sound results on a micro-level. We want to provide a reading assistance solution that both helps the learner and the dyslexia researcher. In order to archive this, we encode adaptation knowledge in a descriptive way by making use of state-ofthe-art ontology-based techniques. This enables a closed-loop approach of continuous improvement. In this paper, we want to present the overall approach as well as initial results of our work within the EU project AGENT-DYSL.

Ontology-Centred Design of an Ambient Middleware for Assisted Living: The Case of SOPRANO
In: Thomas Kirste and Birgitta König-Ries and Ralf Salomon (eds.): Towards Ambient Intelligence: Methods for Cooperating Ensembles in Ubiquitous Environments (AIM-CU), 30th Annual German Conference on Artificial Intelligence (KI 2007), Osnabrück, September 10, 2007, 2007
Abstract The aim of the EU-funded project SOPRANO is to assist older Europeans to lead a more independent life in their familiar environment by means of a next generation smart home with ambient intelligence. The core of the system in each house will be the SOPRANO Ambient Middleware (SAM), which receives the user commands and sensor inputs, enriches them semantically and triggers appropriate reactions via actuators in the house. In this paper, we present a novel approach of an ontology-centred design in order to create SAM as a reliable, deterministic and economically scalable component. Thus, the starting point is the development of a context ontology focussing on the concept of a state. This OWL-Lite ontology is then used as a central reference document during the design process as well as during runtime to abstract from concrete sensor inputs and actuator outputs.

SOBOLEO: vom kollaborativen Tagging zur leichtgewichtigen Ontologie
In: Tom Gross (eds.): Mensch & Computer - 7. Fachübergreifende Konferenz - M&C 2007, Oldenbourg Verlag, 2007, pp. 209-218
Abstract Bisher gibt es kein integriertes Werkzeug, das sowohl die kollaborative Erstellung eines Indexes relevanter Internetressourcen („Social Bookmarking“) als auch einer gemeinsamen Ontologie, die zur Organisation des Indexes genutzt wird, integriert unterstützt. Derzeitige Werkzeuge gestatten entweder die Erstellung einer Ontologie oder die Strukturierung von Ressourcen entsprechend einer vorgegebenen, unveränderlichen Ontologie bzw. ganz ohne jegliche Struktur. In dieser Arbeit zeigen wir, wie sich kollaboratives Tagging und kollaborative Ontologieentwicklung vereinen lassen, so dass jeweilige Schwächen vermieden werden und die Stärken einander ergänzen. Wir präsentieren SOBOLEO, ein System, das kollaborativ und web-basiert die Erstellung, Erweiterung und Pflege von Ontologien und gemeinsamer Lesezeichensammlung ermöglicht und gleichzeitig die Annotierung von Internetressourcen mit Konzepten aus der erstellten Ontologie unterstützt.

Wikis as a Technology Fostering Knowledge Maturing: What we can learn from Wikipedia
In: 7th International Conference on Knowledge Management (IKNOW '07), Special Track on Integrating Working and Learning in Business (IWL), 2007
Abstract The knowledge maturing theory opens an important macro perspective within the new paradigm of work-integrated learning. Especially wikis are interesting socio-technical systems to foster maturing activities by overcoming typical barriers. But so far, the theory has been mainly based on anecdotal evidence collected from various projects and observations. In this paper, we want to present the results of a qualitative and quantitative study of Wikipedia with respect to maturing phenomena, identifying instruments and measures indicating maturity. The findings, generalized to enterprise wikis, open the perspective on what promotes maturing on a method level and what can be used to spot maturing processes on a technology level.

User-Driven Semantic Wiki-based Business Service Description
In: 3rd International Conference on Semantic Technologies (I-Semantics 07), Graz, 2007
Abstract A key factor for success of companies operating in a globalized market environment is a modern SOA-based infrastructure. An essential component of a SOA infrastructure is the central service registry. Current standards for organizing service registries and their implementations are driven by the technical aspects of the infrastructure. When using such technically organized service registries, business users often fail to find the needed information. With the concepts of Web 2.0 in mind, we present a new approach to the organization and implementation of the business registries that are driven by the needs of business users. The paper discusses the problems of the current technically driven approaches, presents an architecture for a business user-driven service registry and introduces an implementation of the architecture using UDDI and Semantic MediaWiki.

Microlearning and the Knowledge Maturing Process: Towards Conceptual Foundations for Work-Integrated Microlearning Support
In: Martin Lindner and Peter A. Bruck (eds.): Micromedia and Corporate Learning. Proceedings of the 3rd International Microlearning 2007, Innsbruck, Austria, June 2007, Innsbruck University Press, 2007, pp. 99-105
Abstract As a response to the new flexibility in work environments, work-integrated learning on demand is an appropriate form of learning which is in line with microlearning ideas. But in a world of microcontent, we need to consider that not all content is appropriate for everybody. The knowledge maturing process allows for distinguishing between different levels of maturity, and technical learning support based on the maturity level can provide automated guidance to make microlearning more efficient.

Semantic Desktop Systems for Context Awareness -- Requirements and Architectural Implications
In: 1st Workshop on Architecture, Design, and Implementation of the Semantic Desktop (SemDesk Design), 4th European Semantic Web Conference (ESWC 2007), Innsbruck, Austria, 2007
Abstract Semantic Desktop systems appear to be a promising infrastructure for context-aware applications that acquire and make use of user context information in order to provide more efficient interaction between the user and the system. In a systematic analysis, we have analyzed existing Semantic Desktop systems based on a collection of requirements and deduced from it architectural implications for future Semantic Desktop development.

Ontology Maturing: a Collaborative Web 2.0 Approach to Ontology Engineering
In: Natasha Noy and Harith Alani and Gerd Stumme and Peter Mika and York Sure and Denny Vrandecic (eds.): Proceedings of the Workshop on Social and Collaborative Construction of Structured Knowledge (CKC 2007) at the 16th International World Wide Web Conference (WWW2007) Banff, Canada, May 8, 2007, CEUR Workshop Proceedings vol. 273, 2007
Abstract Most of the current methodologies for building ontologies rely on specialized knowledge engineers. This is in contrast to real-world settings, where the need for maintenance of domain specific ontologies emerges in the daily work of users. But in order to allow for participatory ontology engineering, we need to have a more realistic conceptual model of how ontologies develop in the real world. We introduce the ontology maturing processes which is based on the insight that ontology engineering is a collaborative informal learning process and for which we analyze characteristic evolution steps and triggers that have users engage in ontology engineering within their everyday work processes. This model integrates tagging and folksonomies with formal ontologies and shows maturing pathways between them. As implementations of this model, we present two case studies and the corresponding tools. The first is about image-based ontology engineering (introducing so-called imagenotions), the second about ontology-enabled social bookmarking (SOBOLEO). Both of them are inspired by lightweight Web 2.0 approaches and allow for realtime collaboration.

A Socially-Aware Desktop for e-Science: Supporting Learning in Networked Scientific Processes
In: Norbert Gronau (eds.): 4th Conference on Professional Knowledge Management - Experiences and Visions (WM 2007), Workshop on Collaborative Knowledge Management (CoKM), GITO, 2007, pp. 47-54
Abstract Research is likely to be the most knowledge-intensive environment, and it seems to be quite surprising that so far knowledge management (KM) techniques from business environments have not been transferred to e-science initiatives in order to improve the efficiency of scientific work on a larger scale. An empirical analysis accomplished in the research area of rapid prototyping has unveiled that due to the high variability and unpredictability of scientific work processes, state-of-the-art business process-oriented KM approaches are not applicable and that scientific work processes need a different paradigm understanding knowledge processes as informal learning processes with a high level of social interaction. For this purpose, we present the model of a "knowledge-added process" as a foundation and a socially-aware desktop as an appropriate tool paradigm.

Characterizing Knowledge Maturing: A Conceptual Process Model for Integrating E-Learning and Knowledge Management
In: Norbert Gronau (eds.): 4th Conference Professional Knowledge Management - Experiences and Visions (WM '07), Potsdam, GITO, 2007, pp. 325-334
Abstract Knowledge management and e-learning both attempt to support learning and knowledge transfer in organizations. However, they aim at knowledge of different degrees of maturity. Central hypothesis of this paper is that the approaches can be integrated on the basis of a process that explicitly aims at designing the transitions of knowledge along varying degrees of maturity. The knowledge maturing process is presented as a conceptual model for explaining and analyzing disruptions in the inter-individual flow of knowledge within organizations. These disruptions can be attributed to a fragmented systems landscape and separated organizational units that foster knowledge of different degrees of maturity. The paper presents criteria for a characterization of this process model and discusses its implications for the design of learning support systems.

Knowledge Maturing as a Process Model for Describing Software Reuse
In: 4th Conference Professional Knowledge Management - Experiences and Visions (WM '07), Potsdam, Workshop on Learning Software Organizations (LSO 07), GITO, 2007, pp. 155-164
Abstract Software reuse has become a major topic in software engineering since reusing artifacts has an important effect on the cost and quality of software products. Accordingly, understanding and managing the mechanisms of software reuse is important for every organization that develops software. In this paper we describe a knowledge maturing process in software engineering and use it to analyze two cases of reusable software artifacts. We argue that the "reusability" of a software artifact is not just an immanent property of the artifact itself, but depends on the "maturity" of the knowledge the artifact embodies. We show that the notion of knowledge maturing can serve as a useful lens for understanding reuse processes and suggest further investigations towards a more holistic concept of reusability.

Expert Finding as Informal Learning Support: Competency-Aware and Socially-Aware
In: First International ExpertFinder Workshop (EFW'07), 2007
Abstract Expert finding goes beyond identifying and locating experts. We see expert finding embedded into informal learning activities where personal and social context plays a decisive role (e.g. looking for colleagues to ask for help). That means on social context level, we need social relationship models describing not only objective but also subjective opinions about relationships' quality. On personal context level, we need shared competence models describing experts and the purpose of interacting with them. With this approach we make expert finding competency- and socially-aware.

Kontextbewusste Lernunterstützung für das Lernen bei Bedarf
In: A. M. Heinecke and H. Paul (eds.): Mensch & Computer - 6. Fachuebergreifende Konferenz - M&C 2006, Oldenbourg Verlag, 2006, pp. 283-292
Abstract Die Flexibilisierung der Arbeitswelt führt zu einer Individualisierung der Bildungspfade, für die zunehmend das praktizierte Lernen auf Vorrat nicht mehr gerecht wird. Ein Wandel hin zu einem Lernen bei Bedarf erfordert allerdings auch einen Wandel der Rolle von lernunterstützenden Systemen. Als Methode hierfür präsentieren wir das kontextgesteuerte Lernen und zeigen, wie sich Lernen sowohl durch klassische Lernobjekte als auch durch zwischenmenschliche Kommunikation mittels Berücksichtigung des Kontextes initiieren und verbessern lässt.

Towards a Human Resource Development Ontology for Combining Competence Management and Technology-Enhanced Workplace Learning
In: Robert Meersman and Zahir Tahiri and Pilar Herero (eds.): On The Move to Meaningful Internet Systems 2006: OTM 2006 Workshops. Part I. 1st Workshop on Ontology Content and Evaluation in Enterprise (OntoContent 2006), Lecture Notes in Computer Science vol. 4278, Springer, 2006, pp. 1078--1087
Abstract Competencies as abstractions of work-relevant human behaviour have emerged as a promising concept for making human skills, knowledge and abilities manageable and addressable. On the organizational level, competence management uses competencies for integrating the goal-oriented shaping of human assets into management practice. On the operational and technical level, technologyenhanced workplace learning uses competencies for fostering learning activities of individual employees. It should be obvious that these two perspectives belong together, but in practice, a common conceptualization of the domain is needed. In this paper, we want to present such a reference ontology that builds on existing approaches and experiences from two case studies.

A Layered Model for User Context Management with Controlled Aging and Imperfection Handling
In: Thomas R. Roth-Berghofer and Stefan Schulz and David B. Leake (eds.): Modeling and Retrieval of Context. Proceedings of the 2nd International Workshop on Modeling and Retrieval of Context MRC 2005, Edinburgh, Scotland, July 31 - August 1, 2005, Lecture Notes in Artificial Intelligence vol. 3946, 2006
Abstract Current research in context-awareness is biased toward low-level context information. High-level context information, however, poses several challenges to context management systems, which can be traced back to the asynchronicity of context acquisition and use and the inherent dynamics and imperfection in that process. This paper presents a three layer model allowing for dealing with the problems of imperfection and aging in a controlled way. It conceives the problem of high-level user context management as an information management problem with specific requirements. The approach has been applied to a context-aware learning environment for corporate learning support.

Systematische Personalentwicklung mit ontologiebasierten Kompetenzkatalogen: Konzepte, Erfahrungen, Visionen
In: Norbert Gronau and Jane Fröming and Simone Schmid (eds.): Fachtagung Kompetenzmanagement - Schulung, Staffing und Anreizsysteme, Potsdam, 5.10.2006, GITO, 2006
Abstract Ontologiebasierten Kompetenzkatalogen kommt im Rahmen des Kompetenzmanagements eine Schlüsselrolle zu. Auf methodischer Ebene dienen sie dazu, Personalentwicklungsstrategien konstruktiver zu diskutieren sowie strategische und operative Ebene besser miteinander zu vernetzen. Auf technologischer Ebene kann derselbe Katalog bzw. eine unmittelbare Verfeinerung/Erweiterung zur (Teil-)Au-tomatisierung von Personalprozessen genutzt werden, um so kompetenzbasierte Personalentwicklung effizienter zu gestalten. Gezeigt wird dies an zwei Beispielen: dem integrierten Ansatz der DaimlerChrysler AG, Werk Wörth und dem Ansatz zur Bildungsbedarfsplanung und -steuerung am Städtischen Klinikum Karlsruhe. Abschließend soll ein Ausblick gegeben werden, wie Kompetenzkataloge auch zur Unterstützung des Lernens bei Bedarf (z.B. durch Generierung von individuellen Bildungsempfehlungen) am Arbeitsplatz genutzt werden können (am Beispiel des Forschungsprojektes Learning in Process).

Context-Aware Workplace Learning Support: Concept, Experiences, and Remaining Challenges
In: Wolfgang Nejdl and Klaus Tochtermann (eds.): Innovative Approaches for Learning and Knowledge Sharing. First European Conference on Technology-Enhanced Learning (EC-TEL 2006), Creete, Greece. Proceedings., Lecture Notes in Computer Science vol. 4227, Springer, 2006, pp. 518-524
Abstract Workplace learning offers the unique possibility of the immediacy of purpose and real-world context. In order to leverage on this, we have developed a context-aware method to support workplace learning. In this paper, we want to describe the concept of context-steered learning, both from a content-driven and communication-driven perspective, and present corresponding system functionality primitives.

Ontology-based Competence Management for Healthcare Training Planning - A Case Study
In: 6th International Conference on Knowledge Management (I-KNOW 06), Graz, 2006
Abstract With the increased pressure towards economic efficiency, hospitals and other healthcare institutions need to reengineer their internal organization and processes. This challenges human resources development with increased efficiency of training in general. We have developed a competence management concept for training planning at a big German hospital with a special focus on critically analyzing the suitability of state-of-the-art ontology-based approaches for the area of nursery. Experiences from the case study show the general feasibility, but also crucial issues summarized in this paper.

Ontology-based User Context Management: The Challenges of Dynamics and Imperfection
In: Robert Meersman and Zahir Tahiri (eds.): On the Move to Meaningful Internet Systems 2006: CoopIS, DOA, GADA, and ODBASE. Part I., Lecture Notes in Computer Science vol. 4275, Springer, 2006, pp. 995--1011
Abstract Robust and scalable user context management is the key enabler for the emerging context- and situation-aware applications, and ontology-based approaches have shown their usefulness for capturing especially context information on a high level of abstraction. But so far the problem has not been approached as a data management problem, which is key to scalability and robustness. The specific challenges lie in the imperfection of high-level context information, its time-dependence and the variability in the dynamics between its different elements. The approach presented in this paper presents a layered data model which structures the problems and is geared towards flexible and efficient query processing in combination of relational database and logic-based techniques. The techniques have been successfully applied for context-aware corporate learning support.

Don’t Annoy the Informal Teacher: Context-Aware Mediation of Communication for Workplace Learning
In: Klaus Tochtermann and Hermann Maurer (eds.): Proceedings of I-KNOW 2006, Special Track on Integrating Working and Learning, Springer-Verlag, 2006, pp. 429-436
Abstract The verbal inter-human exchange forms an important part of informal learning, especially in workplace learning. Where informal learning is taking place within communication, there informal teaching also takes place; but the side of the informal teachers, who are also integrated into work and learning processes, and from which they are distracted from, has been neglected so far. As a method we present in this paper the context-aware mediation of communication between the learner and the informal teacher.

Socially-Aware Informal Learning Support: Potentials and Challenges of the Social Dimension
In: Martin Memmel and Daniel Burgos (eds.): Proceedings of the 2nd International Workshop on Learner-Oriented Knowledge Management and KM-Oriented Learning (LOKMOL 06), in conjunction with the First European Conference on Technology-Enhanced Learning (ECTEL 06), 2006, pp. 19-25
Abstract With increasingly conceiving learning as a social activity, technological support must become more aware of the social context of the individual in order to be able to provide adequate support. But many issues related to making systems socially aware are subject to ongoing research, e.g., the description and mining social relationships, and especially privacy preserva-tion. This paper wants to give a brief overview which possibilities social awareness can offer, and to present a research agenda for realizing these potentials.

Bridging the Gap between Knowledge Management and E-Learning with Context-Aware Corporate Learning.
In: WM 2005: Professional Knowledge Management - Experiences and Visions, Contributions to the 3rd Conference Professional Knowledge Management - Experiences and Visions, April 10-13, 2005, Kaiserslautern, Germany, DFKI, 2005, pp. 170-175
Abstract Knowledge management and e-learning both address the same fundamental problem: facilitating learning in organizations. But they approach the problem with two different paradigms, resulting in two different types of system. This paper proposes context awareness with respect to the learner’s or employee’s context as a solution to bridge the gap. The project Learning in Process is illustrating a step into that direction.

Knowledge Maturing and the Continuity of Context as a Unifying Concept for Knowledge Management and E-Learning
In: Proceedings of I-KNOW 05, Graz, Austria, 2005
Abstract Although both e-learning and knowledge management are about facilitating learning in organization, the major obstacle to bring both of them together can be traced back to different paradigms of learning, resulting from the different nature of the knowledge they are dealing with. In this paper, a knowledge maturing process is presented to illustrate the change of nature and the discontinuities. This lays the foundation for a better understanding. In order to overcome the discontinuities, the consideration of context is proposed, which offers the required continuity.

Context-Steered Learning: The {Learning in Process} approach
In: IEEE International Conference on Advanced Learning Technologies (ICALT '04), IEEE Computer Society, 2004, pp. 684-686
Abstract Context-steered learning in enterprises promises both from a learner point of view and from an organizational point of view higher learning efficiency and improved quality control. We present the Learning in Process approach for contextualizing learning processes in a corporate setting. Its nucleus is a matching component compiling personalized learning programs on demand from modular learning objects.

User Context Aware Delivery of E-Learning Material: Approach and Architecture
In: I-KNOW 2003, 2003
Abstract Current E-Learning solutions are not sufficiently aware of the context of the learner, i.e. the individual characteristics, the organization and the work processes and tasks. This can be achieved by modular learning objects and semantical metadata for their contextualization. This allows to deliver learning material that is relevant to the current situation of the learner. This paper presents the general approach and the architecture.

Automation of Metadata Repository Generation with XML Schema
In: Werner Pilmann and Klaus Tochtermann (eds.): Environmental Communication in the Information Society. 16th International Conference Informatics for Environmental Protection, 2002, pp. 400-407
Abstract Metadata standards have been discussed since years in the environmental domain. Although the community has agreed that metadata are important for information finding, an globally accepted standard is still missing. Different requirements in diverse environmental application domains, countries and organisations have led to a huge variety on metadata vocabularies and technologies. Even projects using existing standards tend to adjust them slightly to their own requirements. A consequence is that new metadata repositories are developed or adapted to the new meta data element sets over and over again . In this paper we present a novel approach for the automation of metadata repository development. As input the system requires only an XML Schema describing the metadata vocabulary. Out of this schema the user interface, database schema and the search, retrieval and upload mechanism are generated during a batch process. The user interface layout can be further controlled by templates. The system is developed for the NOKIS project and evaluated by generating a metadata repository for an adjusted ISO 19115 metadata element set.
