SemTalk EON2003 Semantic Web Export / Import Interface Test

SemTalk
  • MS-Visio based generic graphical modeling tool
  • Main application areas (all of them use ontologies)
    • Business Process Modeling
    • Product Configuration
    • Ontology Modeling
  • Open meta model defines other graphical methods
  • Generates
    • HTML
    • MS Word
    • MS PowerPoint
    • MS Project

Simple SemTalk Ontology

SemTalk Engine
  • Consistency is maintained by a built-in engine within each document


  • Expressiveness is somewhere between RDFS and OWL
    • multiple inheritance
    • instances
    • object and data property types

  • UML-style object notation


  • Covers most ontology / taxonomy modeling requirements related to BPM and Knowledge-Management.

OWL Stencil
6
Interfaces to Inference Engines
  • F-Logic based interface to Ontobroker / OntoEdit from Ontoprise GmbH (we have also used DAML)


  • Cerebra Construct is 100% compatible with SemTalk.
    • OWL & Visio drawing
    • Construct is integrated with the Cerebra Engine of Network Inference Ltd.

Summary
  • SemTalk failed to import DAML models with complex expressions
  • This issue has already been fixed for the OWL template
  • SemTalk succeeded in importing taxonomies from all tools, which support DAML or RDFS
  • From a business point of view, the inability to import models that have axioms and rich logical expressions is not very relevant since those expressions are not included in the other SemTalk methodologies such as Business Process Modeling.  Being able to import taxonomies with subclassing and properties is the main requirement of our current customers.
