Résumé

Information retrieval, IR, the science of extracting information from any potential source, can be viewed in a number of ways: logical, probabilistic and vector space models are some of the most important. In this book, the author, one of the leading researchers in the area, shows how these views can be reforged in the same framework used to formulate the general principles of quantum mechanics. All the usual quantum-mechanical notions have their IR-theoretic analogues, and the standard results can be applied to address problems in IR, such as pseudo-relevance feedback, relevance feedback and ostensive retrieval. The relation with quantum computing is also examined. To keep the book self-contained appendices with background material on physics and mathematics are included. Each chapter ends with bibliographic remarks that point to further reading. This is an important, ground-breaking book, with much new material, for all those working in IR, AI and natural language processing.

L'auteur - Keith van Rijsbergen

Keith van Rijsbergen's research has, since 1969, been devoted to information retrieval (IR), covering both theoretical and experimental aspects. His current research is concerned with the design of appropriate logics to model the flow of information and the application of Hilbert Space theory to content-based IR. This is his third book on IR; his first is now regarded as the classic text in the area. In addition he has published over 100 research papers and is a regular speaker at major IR conferences.

He is a fellow of the IEE, BCS, ACM, and the Royal Society of Edinburgh. In 1993 he was appointed Editor-in-Chief of The Computer Journal, an appointment he held until 2000. He is an associate editor of Information Processing and Management, on the editorial board of Information Retrieval, and is on the advisory board of the Journal o/Web Semantics. He has served as a programme committee member and editorial board member of the major IR conferences and journals. He is a nonexecutive director of a start-up: Virtual Mirrors Ltd.
