AQUAINT: Meaning-Oriented Question-Answering with Ontological Semantics

This project is from a team consisting of New Mexico State University's Computing Research Laboratory (CRL) of Las Cruces, NM, the Institute for Language and Information Technologies, University of Maryland Baltimore County (ILIT), and CoGenTex.

The CRL/ILIT/CoGenTex team proposes a comprehensive system-level effort covering all three main technical areas:

  • question understanding and interpretation;
  • determining the answer;
  • presenting the answer.
The first complete version of the proposed system will concentrate on answering questions about travel and meetings, and will use two kinds of data sources:
  • open text (in English, Arabic and one of Persian, Russian or Spanish, selected in consultation with ARDA);
  • a structured database, called a fact database (Fact DB), whose entries are instances of concepts in the system's ontology, or world model.
The Fact DB, the ontology and the lexicons for the three languages, together with the working memory that includes the intermediate results of the system's operation, are the major static knowledge sources in the proposed system.
