Flexible Query Answering Systems: Third International Conference, FQAS'98, Roskilde, Denmark, May 13-15, 1998, Proceedings (Lecture Notes in Computer Science, 1495)

This Book Constitutes The Thoroughly Refereed Post-workshop Proceedings Of The Third International Conference On Flexible Query Answering Systems, Fqas'98, Held In Roskilde, Denmark, In May 1998. The 32 Revised Papers Presented Were Carefully Reviewed And Went Through Two Rounds Of Selection For Inclusion In The Proceedings. This Book Is The First One Focused On Flexible Query Answering Systems; This Emerging Area Of Research And Development Builts On Results From Mathematical Logic, Fuzzy Logic, Various Database Paradigms, Information Retrieval, Linguistics, And Human Computer-interaction. The Papers Deal With Issues Occuring In Querying Databases And The Internet.
