  Semantic Meeting Memory

  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 AuerRapidOWL - 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 SureA
  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
COLLABORATION BETWEEN WORKS

• Collaborations amongst presented projects
  explored for workshop report

20
STICA 2007?

• Depends on the Organization
• Union with other WETICE Workshop
• Questions?
