Tools Applications Methodologies Summary of the Best Workshop Paper

Results and Conclusions Open Issues Identified Collaboration between works

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

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

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.

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.

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…

VIMethCOE METHODOLOGY (I)

Need for new methodologies that consider new dimensions in the development of Ontologies

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.

VIMethCOE METHODOLOGY (III)

Proposed Requirements: Modularization Local Adaptation Knowledge Abstraction Definition of Personal Modules: Views Argumentation and Consensus

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

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.

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

VIMethCOE METHODOLOGY (VII)

In VIMethCOE we propose the coexistence of several overlapped knowledge spaces:

STICA 2006

Results and Conclusions

Open Issues Identified

Collaboration between works

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”

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

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
