07/12/02 (Competence Ontology)

Topic: DFKI-KM Competence Ontology

• 2 Papers on Competence Modeling and Organizational Memories (see reading list)
• AL presents state of the DFKI-KM competence model ( ppt-Slides , zipped Protégé-Project )
  Basic design decisions:
  * The objects where the competencies relate to are instances (of "software" or "technology").
  * A specific competency holds the information whether it is an "wants to learn" competency or not, and whether it is an "avoid" competency or not.
• LvE presents his first sketch for competence modeling ( zipped Protégé-Project )
  Basic design decisions:
  * The objects where the competencies relate to are modeled as classes (namely "SoftwareArtifact"-subclasses and "Topic"-subclasses.
  * A competency relates a competence object (software or abstract topic) to a competence level (which is discretely described and may also include some "outdated" marker ("Having used Perl heavily a long time ago").
  * A person has actual competencies and desired competencies (remark LvE: it may be more appropriate to model the "outdated" info here at the person, not at the competence level).
• Discussion: mainly about the possible semantics of "avoid" and the general "ontology-instance line" problem
• Next meeting: LvE will not be present and asks for an ersatzchair to co-oordinate the next meeting (LvE's wish: postpone the "onto basics" topic until I´m back!). BK volunteers to co-ordinate the next meeting (Friday, 26th).
