ThisvolumeconstitutestheproceedingsoftheFifthInternationalConferenceon Flexible Query Answering Systems, FQAS 2002, held in Copenhagen, Denmark on October 27-29, 2002. FQAS is the premier conference for researchers and practitioners concerned with the vital task of providing easy, ? exible, and intuitive access to information for every type of need. This multidisciplinary conference draws on several re- arch areas, including databases, information retrieval, knowledge representation, soft computing, multimedia, and human-computer interaction. Previous FQAS events were held in 1994, 1996, 1998, and 2000. The overall theme of the FQAS conferences is innovative query systems - medatprovidingeasy, ? exible, andintuitiveaccesstoinformation. Suchsystems are intended to facilitate retrieval from information repositories such as data- ses, libraries, andtheWorld-WideWeb. Theserepositoriesaretypicallyequipped with standard query systems which are often inadequate, and the focus of FQAS is the development of query systems that are more expressive, informative, c- perative, and productive. These proceedings contain 29 original papers that relate to the topic of users posing queries and systems producing answers. The papers cover the ? elds: - tabase Management, Information Retrieval, Domain Modeling, Knowledge - presentation and Ontologies, Knowledge Discovery and Data Mining, Arti? cial Intelligence, Classical and Non-classical Logics, Computational Linguistics and Natural Language Processing, Multimedia Information Systems, and Human- Computer Interaction. We wish to thank the contributors for their excellent papers and the referees, publisher, and sponsors for their e? ort. Special thanks also to the invited sp- kers, members of the Advisory Board, and members of theProgram Committee. They made the success of FQAS 2002 possible.
