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. 606 $aComputer science$xMathematics 606 $aInformation storage and retrieval systems$xMathematics 615 0$aComputer science$xMathematics. 615 0$aInformation storage and retrieval systems$xMathematics. 676 $a025.04 700 $aVan Rijsbergen$b C.
