prot g 2000
Protégé-2000
  • Supports modeling of ontologies and use of ontologies to guide acquisition of content knowledge from domain experts
  • Allows developers to “plug in” new components easily to add new functionality
prot g 20001
Protégé-2000
  • Knowledge model
    • Frame-based
    • OKBC compatible
  • Features
    • Editors for browsing, building and maintaining knowledge bases (KBs)
    • API for programmatic access to the KB
    • Extensible GUI (via Java beans)
    • Multiple output formats for archival storage

prot g 200 plugins
Protégé-200 plugins
  • Domain-specific user-interface plugins
  • Alternative back ends for archival storage
  • Utility programs for knowledge-acquisition tasks
  • End-user applications
resource description framework
Resource Description Framework
  • A standard under development by the World-Wide Web Consortium to encode rich “metadata” within Web pages
  • Designed for use by future e-commerce applications
  • RDF provides a meta-ontology and an ontology language and with XML-based syntax
rdf support in prot g 2000
RDF support in Protégé-2000
  • Reads and writes
    • ontologies as RDF-schema documents
    • knowledge-base instances as RDF files
  • Currently supports RDF semantics compatible with those of OKBC
  • Handles creation and parsing of RDF syntax completely transparently
summary
Summary
  • Protégé provides:
    • An extensible knowledge-base development environment
    • A methodology for building knowledge-based solutions
    • A clear specification of its representational semantics A variety of persistent storage options
