Natural Language Processing â€“ NL/DB Interfaces, Machine Translation, Speech Prosody
Professor: Cercone, Nick
Research Area: Natural Language Processing
SYSTEMX, our prototype natural language interface (English to SQL translator) to relational databases resulted in several state-of-the-art advances. These advances include design and implementation of an HPSG parser for multiple domains, inheritance reasoning for HPSG, learning of semantic & syntactic information through dialog, computing & utilizing correct navigation (join path) information during interface usage, and portability. We stimulate â€śtechnology transferâ€ť with Rogers Cablesystems Ltd. (customer service), Environment Canada (information holdings), SaskTel (marketing) and NSERC (grants information database). We applied SYSTEMX technology in cooperation with Sask Health; this collaboration resulted in the HERMES database interface to a simulated Sask health database.
