- Abstract
- Das Information Retrieval steht in theoretischer und praktischer Hinsicht im Zentrum der Informationswissenschaft. Das Buch vereinigt beide Bereiche, indem es seinen praktischen Ausgang von realen Situationen der Online-Informationsvermittlung nimmt und zugleich einen wichtigen Beitrag zu einer Theorie der Frageformulierung in Information Retrieval an sich leistet. Mit 'realen Situationen' sind mitprotokollierte Online-Sitzungen bzw. CD-ROM Recherchen gemeint. Diese Recherchen wurden teils kooperativ, d.h. zusammen mit den Endbenutzern, oder nicht-kooperativ, d.h. alleine von professionellen Informationsvermittlern, durchgeführt und in der Arbeit ausgewertet. Die Studie ist damit der sog. verhaltensanalytischen Richtung des Information Retrieval zuzurechnen

- Abstract
- This book discusses many of the key design issues for building search engines and emphazises the important role that applied mathematics can play in improving information retrieval. The authors discuss not only important data structures, algorithms, and software but also user-centered issues such as interfaces, manual indexing, and document preparation. They also present some of the current problems in information retrieval that many not be familiar to applied mathematicians and computer scientists and some of the driving computational methods (SVD, SDD) for automated conceptual indexing
