Prot g 2000
Protégé-2000 Environment

  • 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 Environment

  • 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


Building knowledge bases the prot g methodology
Building knowledge bases: EnvironmentThe Protégé methodology

Protégé

Domain ontology

to provide domain

of discourse

Knowledge-acquisition tool

for entry of detailed content

Prot g 200 plugins
Protégé-200 plugins Environment

  • 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 Environment

  • 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 Environment

  • 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 Environment

  • 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
