Title
Question answering from frequently asked question files : experiences with the FAQ Finder System
Source
AI magazine. 18(1997) no.2, S.57-66
Year
1997
Abstract
Describes FAQ Finder, a natural language question-answering system that uses files of frequently asked questions as its knowledge base. Unlike information retrieval approaches that rely on a purely lexical metric of similarity between query and document, FAQ Finder uses a semantic knowledge base (Wordnet) to improve its ability to match question and answer. Includes results from an evaluation of the system's performance and shows that a combination of semantic and statistical techniques works better than any single approach
