Title Web-Based List Question Answering
Venue International Conference on Computational Linguistics
Session Main Conference
Year 2004

While research on question answering has be- come popular in recent years, the problem of ef- ficiently locating a complete set of distinct answers to list questions in huge corpora or the Web is still far from being solved. This paper ex- ploits the wealth of freely available text and link structures on the Web to seek complete answers to list questions. We introduce our system, FADA, which relies on question parsing, web page classification/clustering, and content extrac- tion to find reliable distinct answers with high re- call.
