2. AGENDA • Topics of the Workshop • Papers Presented • Tools • Applications • Methodologies • Summary of the Best Workshop Paper • Results and Conclusions • Open Issues Identified • Collaboration between works

3. TOPICS OF THE WORKSHOP • Methodologies for collaboratively creating and managing shared information • Collaborative ontology engineering • Semantic collaboration applications • Collaborative Semantic Web portals • Semantic community support systems • Semantic Wikis • Semantic Blogging • Semantic Mindmapping and Conceptmapping • Studies on the value added to collaboration by semantic technologies • Future research directions in the area of semantic collaboration

4. TOOLS • Ivan Cantador, Pablo Castells, David Vallet: Enriching Group Profiles with Ontologies for Knowledge-driven Collaborative Content Retrieval • Proposes a Study of social choice theory based strategies to combine ontology-based user profiles • Presents a multimedia retrieval system based on group profiles • Bi Chen, He Tan, Patrick Lambrix: Structure-based filtering for ontology alignment • Proposes a New algorithm for ontology alignment • Provides Support for effective collaboration

5. APPLICATIONS • Danius Michaelides, Simon Buckingham Shum, Ben Juby, Clara Mancini, Roger Slack:Memetic: Semantic Meeting Memory • Presents an Environment for recording and replaying meetings • Semantic annotations on content of meetings • Sebastian Schaffert: IkeWiki: A Semantic Wiki for Collaborative Knowledge Management • Presents a Semantic Wiki application • Provides Facilitates for collaborative knowledge engineering through Semantically annotated links, Context representation, Reasoning on the knowledge base, etc.

6. METHODOLOGIES (I) • Sören Auer:RapidOWL - an Agile Knowledge Engineering Methodology • Supports adaptive semantic collaboration between domain experts and knowledge engineers • Based on the idea of iterative refinement, annotation and structuring of knowledge bases • Michael Engler, Denny Vrandecic, York Sure:A Tool for DILIGENT Argumentation: Experiences, Requirements and Design • Presents a Tool for Capturing argumentations in distributed ontology engineering processes.

7. METHODOLOGIES (II) • A View-based Methodology for Collaborative Ontology Engineering: an Approach for Complex Applications (VIMethCOE) • Ernesto Jiménez Ruiz, Rafael Berlanga • Temporal Knowledge Bases Group • University Jaume I of Castellon • Selected as the best workshop paper based on the reviews…

8. VIMethCOE METHODOLOGY (I) • Need for new methodologies that consider new dimensions in the development of Ontologies

9. VIMethCOE METHODOLOGY (II) • How to Achieve a Good Balance Between Dimensions? • We want to achieve • A highly Dynamic development. • A Distributed team structure. • And Partially Controlled scenario.

10. VIMethCOE METHODOLOGY (III) • Proposed Requirements: • Modularization • Local Adaptation • Knowledge Abstraction • Definition of Personal Modules: Views • Argumentation and Consensus

11. VIMethCOE METHODOLOGY (IV) • Users works only with a portion of the knowledge: Views. • Views are defined by the developer and they are a kind of module. • The operation through views provide: • Knowledge Abstraction • Facilities for Visualization in ontology editors • Both for the developer and the editor • Reuse of Knowledge

12. VIMethCOE METHODOLOGY (V) • Views can be defined over modules or over other views. • Views are grouped inside a hierarchy depending on their definition and the changes made.

13. VIMethCOE METHODOLOGY (VI) • Phases on the Development: • Complementary to centralized methodologies • We distinguish 5 different phases: • Requirements • Development (Application of Centralized Methodologies) • Publication and Argumentation • Evaluation and Maintenance • Application

14. VIMethCOE METHODOLOGY (VII) • In VIMethCOE we propose the coexistence of several overlapped knowledge spaces:

15. STICA 2006 • Results and Conclusions • Open Issues Identified • Collaboration between works

16. RESULTS AND CONCLUSION (I) • It is worthwhile to “ontologise” at least parts of collaborative applications • It is beneficial to keep argumentations from ontology-engineering processes for reference • Semantic Web based applications represent “future proof”

17. RESULTS AND CONCLUSION (II) • Semantic Web and Wiki dominate current work • Applications and tools currently are centralized and organization based. • However methodologies propose distributed approaches

18. OPEN ISSUES IDENTIFIED • Added value from application of semantic technologies cannot be pin-pointed today • Further semantic technologies and collaboration styles have to be explored (semantic blogs, semantic mindmaps, etc.) • Semantic Interoperability is not taken into account sufficiently, therefore  inter-organizational semantic collaboration is not enabled so far

19. Ontology Alignment (Bi Chen) IkiWiki (Sebastian Schaffert) Enriching Group Profiles (Ivan Cantador) RapidOWL (Sören Auer) DILIGENT (Michael Engler) VIMethCOE (Ernesto Jiménez) Memetic (Danius Michaelides) COLLABORATION BETWEEN WORKS • Collaborations amongst presented projects explored for workshop report

20. STICA 2007? • Depends on the Organization… • Union with other WETICE Workshop • Questions? • Robert Tolksdorf (tolk@inf.fu-berlin.de)
