Simone Braun studied Media Systems at the Bauhaus-University Weimar with focus on Computer-Supported Cooperative Work (CSCW). Since December 2005 she is a research associate at FZI in the research group Information Process Engineering. She is working in the team of Prof. Rudi Studer and the team of Prof. Peter Lockemann within the competence areas Knowledge & Learning and Semantic Technologies. She is further a PhD student of Prof. Rudi Studer.

Her main research interest is collaboration and informal learning support with semantic technologies with focus on collaborative ontology development under special consideration of social aspects.

Within the German BMBF-funded project Im Wissensnetz (“In the Knowledge Web”), she has been investigating how to transfer approaches of (business-oriented) knowledge management and work-integrated learning on demand to scientific working processes under special consideration of informal learning processes and social relationships.

She is further involved in the development of SOBOLEO. SOBOLEO is a tool that combines social semantic bookmarking with collaborative lightweight ontology development. It supports the process of ontology maturing (cf. „Ontology Maturing: a Collaborative Web 2.0 Approach to Ontology Engineering“).

In other projects she worked on transferring the concept of work-integrated learning on demand into future releases of SAP ERP software. She was also involved in the conceptualization of a knowledge management strategy for a large German automotive manufacturer.

Community-driven & Work-integrated Creation, Use and Evolution of Ontological Knowledge Structures

Abstract The thesis aims to support the collaborative development of ontological knowledge structures by communities of knowledge workers in order to facilitate the organization and sharing of information within their domain. One big challenge for today’s organizations and knowledge workers is the focused discovery of new information that is likely to be interesting and useful in order to generate new knowledge. But it is also the organization thus information that had once be found and identified as such can be rediscovered and shared. This is not only about the information itself but also about the people behind who hold the knowledge and e. g., may quickly provide assistance if there are questions. Knowledge about competencies and capabilities of its employees also is an essential need for an organization and its development. This encompasses activities like team staffing or identifying training needs. Research on ontology-based semantic (web) applications has shown that ontologies are well-suited for organizing and retrieving relevant resources being it people or documents because they connect information resources with machine processable background knowledge. However in practice, ontology-based applications still haven’t made their breakthrough. This might be traced back to the high effort and complexity of ontology development. On the other hand, folksonomy-based systems recently have proven to be agile and user-driven approaches for the same application area. They enable their users to collect, manage and share information resources in an easy and lightweight way. However, their lack of semantics also causes a number of problems plaguing tagging and hampering tag-based retrieval. To that end, this thesis explores how we can combine folksonomy- and ontology-based approaches so that we keep their particular advantages and avoid their disadvantages thus supporting communities of knowledge workers in organizing and maintaining a shared information repository. This is investigated in the application of Social Semantic Bookmarking and Semantic People Tagging. We present Ontology Maturing as a new perspective and conceptual model for the collaborative development of ontological knowledge structures. It supports (1) the development of a shared understanding, (2) the translation of Web 2.0 approaches to ontology engineering for more active participation, (3) the incremental formalization, (4) application-orientation & work-integration and (5) usable evolving models. To that end, we analyze the advantages and challenges of ontologies and ontology-based knowledge organization systems and make a comparison and consolidation of ontology spectra in literature as well as of ontology development methodologies and tools. A conceptual design framework complements the ontology maturing model. It supports software developers in deriving and realizing socio-technical systems that scaffold and guide ontology maturing in the application of Social Semantic Tagging for a given organizational setting. It considers technical as well as non-technical aspects. It organizes and provides methods and tools with that end users without modeling expertise can collaboratively organize their information with ontologies and develop the latter one in a work-integrated way. To that end, we analyze the advantages and challenges of folksonomies and folksonomy-based systems and classify tagging motivations and categories in literature. On this basis, we develop a general definition and model of social semantic tagging and its specializations of social semantic bookmarking and semantic people tagging. The SOBOLEO framework presents a flexible culture-system-fit framework and reference implementation of the conceptual model and conceptual design framework. It provides a configurable and extensible architecture as well as reusable reference data models for social semantic bookmarking and semantic people tagging and competence ontology maturing. The review of related work shows that SOBOLEO is a pioneer for SKOS editors and the first implementation for semantic people tagging ever. Following the methodology of design-based research, the model, conceptual design framework and technical framework have been validated and iteratively improved in nine case studies with more than 250 participants involved.

People Tagging and Ontology Maturing: An Enterprise Social Media Approach to Competence Management
International Journal for Knowledge and Learning, vol. , no. , 2012, pp.

Abstract Semantic People Tagging is an Enterprise 2.0-style approach to making expertise and individual capabilities transparent. By combining it with a collaborative ontology editor and thus the possibility to construct a shared vocabulary and understanding, it can be a supplement for cumbersome competence management, or expert nder solutions, which lack acceptance among employees, and suer from outdated data. It gives human resources a timely overview of available and required competencies based on peer reviews and actual usage. However, it also needs to be tailored to the cultural characteristics of a speci c company. Therefore, we have developed a design framework for semantic people tagging. We want to present the general approach based on the ontology maturing concept of gradual formalization and its implementation based on a social semantic bookmarking system. Focus group interviews with HR experts have further yielded insights into the wider context and validated the concept. The system has been introduced and evaluated at a company for career advising.

Culture Awareness for Supporting Knowledge Maturing in Organizations
In: Motivation und kulturelle Barrieren bei der Wissensteilung im Enterprise 2.0, Workshop auf der Mensch & Computer 2011, 2011

Abstract The success and sustainability of informal learning support at the workplace largely depends on motivational, social, and cultural aspects of the involved individuals, teams, and organizations. In this paper, we present our empirical findings from a large-scale interview-based study on those aspects with respect to knowledge development in companies. We draw some conclusions that influence the development of future culturally aware systems for the enterprise and organizations.

Feedback in Social Semantic Applications
International Journal of Knowledge Engineering and Data Mining (IJKEDM), vol. , no. , 2011, pp.

Abstract This article examines the role of feedback mechanisms in social semantic web applications. It introduces different social semantic applications and the function that system feedback can play in these, although only a small portion of possible roles of feedback in such applications is addressed by the state of the art. The authors present an approach with four concrete feedback mechanisms and an experiment on the use of explicit feedback to foster user contribution and motivation. Finally the article details the large number of open research questions in this area.

The challenge of integrating motivational and affective aspects into the design of networks of practice
In: 2nd International Workshop on Motivational and Affective Aspects in Technology Enhanced Learning (MATEL 11), ECTEL 2011, Palermo, Italy, CEUR Workshop Proceedings, 2011

Abstract In this position paper, we (i) set out the background, problems and questions involved in moving towards a design methodology for incorporating motivational and affective factors in networks of practice, (ii) define networks of practice, highlighting that motivational and affective factors are intertwined with a range of other complex issues, (iii) examine some of these aforementioned problems using a specific example from the MATURE IP (http://mature-ip.eu/) called people tagging, and use this case (iv) to delineate the challenge of integrating motivational aspects into the design of networks of practice.

SOBOLEO – Editor and Repository for Living Ontologies
In: d'Aquin, Mathieu and Castro, Alexander García and Lange, Christoph and Viljanen, Kim (eds.): Proceedings of the 1st International Workshop on Ontology Repository and Editors for the Semantic Work (ORES 2010) at the Extended Semantic Web Conference (ESWC 2010), 2010

Abstract SOBOLEO is a web based system that enables groups of people to collaboratively develop and use SKOS ontologies and semantically organized information spaces. SOBOLEO supports the development and refinement of living ontologies – i.e. ontologies that are never finished and that are used and developed at the same time. It offers tools to edit the SKOS ontology used and the information space. It also offers interfaces for remote applications to be notified of changes and to change the ontology itself.

People Tagging & Ontology Maturing: Towards Collaborative Competence Management
In: Randall, David and Salembier, Pascal (eds.): From CSCW to Web2.0: European Developments in Collaborative Design Selected Papers from COOP08, Computer Supported Cooperative Work vol. , Springer, 2010

Abstract Competence Management approaches 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 sustain-able 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. To overcome these problems, we propose a collabora-tive competence management approach. In this approach, we combine Web 2.0-style bottom-up processes with organizational top-down processes. We addressed this problem as a collaborative ontology construction problem of which the con-ceptual 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. Following evolutionary prototyping within the design-based research methodology we conducted two field experiments in parallel with the system development in order to test the approach of people tagging in general and to explore motivational and social aspects in particular.

Mit Social Semantic Bookmarking zur nützlichen Ontologie
i-com - Zeitschrift für interaktive und kooperative Medien, vol. 8, no. , 2009, pp.

Abstract Dieser Artikel präsentiert das SOBOLEO-System und das zugrundeliegende Ontologiereifungsprozessmodell für die kollaborative Ontologieentwicklung. Man kann beobachten, dass die meisten aktuellen Ontologieentwicklungsprozesse und -werkzeuge von einer organisatorischen, personellen, technischen und zeitlichen Trennung zwischen Entwicklung und Nutzung der Ontologie ausgehen – eine Trennung, die wiederum häufig zu kostspieligen und nicht an ihre Nutzung angepasste Ontologien führt. Unser Ansatz überwindet durch diese Trennung verursachten Schwierigkeiten mittels Methoden und Werkzeuge, die die Nutzer der Ontologie in die Lage versetzen, diese selbst zu entwickeln, und zwar im gleichen System, das die Ontologie nutzt und zu dem Zeitpunkt und Umfang wie jeweils nötig (arbeitsintegriert).

Semantics to the Bookmarks: A Review of Social Semantic Bookmarking Systems
In: International Conference on Semantic Systems (I-SEMANTICS 2009), Graz, Austria, 2009, pp. 445-454

Abstract In this paper we present a review of systems that follow the novel paradigm of Social Semantic Bookmarking. Social semantic bookmarking allows for the annotation of resources with tags extended by semantic definitions and descriptions that also evolve (collaboratively) within the same system. We analyzed nine different systems that extend social bookmarking in the direction of more semantics; i.e. that enable their users to add semantics to the folksonomy. We studied the systems regarding the realization of the social semantic bookmarking paradigm, the features offered to the users to add semantics, what kind of semantics can be added, and how the system makes use of the semantics. We will present commonalities, main differences and distinctive features, and future trends.

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

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.

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.

Social Semantic Bookmarking
In: Practical Aspects of Knowledge Management - 7th International Conference, PAKM2008, Yokohama, Japan, Lecture Notes in Computer Science vol. , 2008

Abstract In this paper we present the novel paradigm of Social Semantic Bookmarking. Social Semantic Bookmarking combines the positive aspects of semantic annotation with those of social bookmarking and tagging while avoiding their respective drawbacks like the cumbersome maintenance of ontologies or the lacking semantic precision of tags. Social semantic bookmarking tools allow for the annotation of internet resources based on an ontology and the integrated maintenance of the ontology by the same people that use it. We introduce Social Semantic Bookmarking and present the SOBOLEO application as an implementation of this paradigm.

Tackling the Curse of Prepayment – Collaborative Knowledge Formalization Beyond Lightweight
In: 1st Workshop on Incentives for the Semantic Web (INSEMTIVE), 7th International Semantic Web Conference ISWC2008, October 27th, 2008, Karlsruhe, Germany, CEUR Workshop Proceedings vol. , 2008

Abstract This paper argues for collaborative incremental augmentation of text retrieval as an approach that can be used to immediately show the benefits of relatively heavyweight knowledge formalization in the context of Web 2.0 style collaborative knowledge formalization. Such an approach helps to overcome the "Curse of Prepayment"; i.e. the hitherto necessary but very large initial investment in formalization tasks before any benefit of Semantic Web technologies is visible. Some initial ideas about the architecture of such a system are presented and it is placed within the overall emerging trend of "people powered search".

Informal learner styles: Individuation, interaction, in-form-ation
In: Schmidt, Andreas and Attwell, Graham and Braun, Simone and Lindstaedt, Stefanie and Maier, Ronald and Ras, Eric (eds.): 1st International Workshop on Learning in Enterprise 2.0 and Beyond, CEUR Workshop Proceedings vol. 383, 2008

Abstract Web 2.0 has sparked tremendously increased interest in IT-supported knowledge management and technology-enhanced learning in organizations. Although there have been abundant activities of how to benefit from Web 2.0 technologies, information on how to go about deploying these in organizational settings in a coordinated manner are scarce. Based on the findings of an ethnographically informed study, this paper presents three idealized, richly described scenarios of informal learner styles which are used in order to develop theses on the relationship of Web 2.0 and workplace learning.

Ontologies, Dialogue and Knowledge Maturing: Towards a Mashup and Design Study

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.

Concept of a Tool Wrapper Infrastructure for Supporting Services in a PLE
In: Schmidt, Andreas and Attwell, Graham and Braun, Simone and Lindstaedt, Stefanie and Maier, Ronald and Ras, Eric (eds.): 1st International Workshop on Learning in Enterprise 2.0 and Beyond, CEUR Workshop Proceedings vol. 383, 2008

Abstract As one of the most relevant way of learning after apprenticeship is the informal learning an implementation of a PLE should try to support the learner by mashing up services and tools of every day work, creates cross links between them and gives motivation and support for personal and individual style of learning. This paper presents implementations and ideas for the whole collection of necessary pieces of software to provide a PLE in a bottom up manner. A server implementation is introduced which is based on a SOA approach and which includes an extractor for metadata of file objects. This module is furthermore able to run a semantic analysis on unstructured texts which results in for example in high-quality keywords and identification of persons. Taking this as technical background the social functions are explained which are identified as the functions a PLE is supposed to provide more than any knowledge management or e-learning software. Closing, these functions are converted in ideas of possible implementations of tools and services, back up by graphical mock-ups.

Von Tags zu semantischen Beziehungen: kollaborative Ontologiereifung
In: Gaiser, Birgit and Hampel, Thorsten and Panke, Stefanie (eds.): Good Tags and Bad Tags - Social Tagging in der Wissensorganisation, Medien in der Wissenschaft vol. 47, Waxmann, 2008, pp. 163-173

Abstract Die Popularität von Tagging-Ansätzen hat gezeigt, dass dieses Ordnungsprinzip für Nutzer insbesondere auf kollaborativen Plattformen deutlich zugänglicher ist als strukturierte und kontrollierte Vokabulare. Allerdings stoßen Tagging-Ansätze oft an ihre Grenzen, wo sie keine ausreichende semantische Präzision ausbilden können. Umgekehrt können ontologiebasierte Ansätze zwar die semantische Präzision erreichen, werden jedoch (besonders aufgrund der schwerfälligen Pflegeprozesse) von den Nutzern kaum akzeptiert. Wir schlagen eine Verbindung beider Welten vor, die auf einer neuen Sichtweise auf die Entstehung von Ontologien fußt: die Ontologiereifung. Anhand zweier Werkzeuge aus dem Bereich des Social Semantic Bookmarking und der semantischen Bildsuche zeigen wir, wie Anwendungen aussehen können, die eine solche Ontologiereifung (in die jeweiligen Nutzungsprozesse integriert) ermöglichen und fördern.

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.

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.

The Ontology Maturing Approach to Collaborative and Work-Integrated Ontology Development: Evaluation Results and Future Directions
In: International Workshop on Emergent Semantics and Ontology Evolution (ESOE), ISWC 2007, Busan/Korea, 2007

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.

SOBOLEO: vom kollaborativen Tagging zur leichtgewichtigen Ontologie
In: Gross, Tom (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.

Ontology Maturing: a Collaborative Web 2.0 Approach to Ontology Engineering
In: Proceedings of the Workshop on Social and Collaborative Construction of Structured Knowledge at the 16th International World Wide Web Conference (WWW 07), Banff, Canada, 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.

Ontology Maturing with Lightweight Collaborative Ontology Editing Tools
In: Gronau, Norbert (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.
