About the Book
These proceedings of the Fourth International Conference on Flexible Query Answering Systems covers the whole array of fields related to users posing flexible queries and (electronic) systems producing answers. The FQAS 2000 Conference has been the premier conference focusing on one of the key issues the information society is facing, namely that of providing easy, flexible, intuitive access to information to everybody. In targeting this issue, the conference draws on several research areas such as databases, querying, information retrieval, knowledge representation, soft computing, cyberspace, multimedia systems, human-computer interaction.This volume provides a unique opportunity for researchers, developers and practitioners to explore new ideas and approaches in a multidisciplinary forum.
