Abstract

The OQAFMA Query Agent for the Foundational Model of Anatomy (OQFMA) was designed to enhance the capabilities of an earlier server and to provide more rapid access to a large knowledge base than the Protégé knowledge acquisition tool. The system architecture was optimized using indexes for the most common classes of queries. Additional performance benefits were gained by pre-computing the transitive closure of appropriate relationships. Flexible, random access of the data is provided via a declarative query language, derived from StruQL, a language for querying semi-structured data. The poster provides several examples of queries supported by OQAFMA.
