Knowledge Based Question Answering,
Abstract
The natural language database query system incorporated in the KNOBS interactive planning system comprises a dictionary driven parser, APE-II, and script interpreter which yield a conceptual dependency conceptualization as a representation of the meaning of user input. A conceptualization pattern matching production system then determines and executes a procedure for extracting the desired information from the database. In contrast to syntax driven X-A systems, e.g., those based on ATN parsers, APE-II is driven bottom-up expectations associated with word meanings. The processing of a query is based on the contents of several knowledge sources.
