Improving query-answers from domain knowledge
Troels Andreasen · 2002
The paper introduces an approach to open knowledge-based query evaluation and describes a preliminary prototype taking this approach. A knowledge-base (KB), complementing the primary information base, that defines and relates words and concepts and exploits similarities between concepts, is used to improve answers. The knowledge base may introduce common and/or domain specific knowledge. The overall approach is to apply the KB in combination with a highly parameterised matching and aggregation, such that queries are transformed and expanded through the KB and parameters are resolved from the KB.
