Exploration of a Geometric Model of Data Fusion.
Ibraev, Ulukbek; Ng, Kwong Bor; Kantor, Paul B. – Proceedings of the ASIST Annual Meeting, 2002
Explores aspects of data fusion (DF) for information retrieval (IR) using a set of data from the Fifth International Conference on Text Retrieval (TREC5). Derives an equation for effective DF based on a geometric model and shows that the performance of a pair of IR schemes may be approximated by a quadratic polynomial. (Author/LRW)

Measurement of Information.
Peer reviewed Peer reviewed
Hayes, Robert M. – Information Processing and Management, 1993
Presents and discusses implications of a set of measures of information. Definitions of relevant terms, including fact, data, representation, information, and knowledge, are given; four levels of processing data are explained (i.e., data transfer, data selection, data analysis, and data reduction); and relationships between information and…

Development of a Responsive Library Acquisitions Formula. Final Report.
Evans, Glyn T.; And Others – 1978
The major accomplishments in the development of a management system for academic library collection development were (1) the development of translation tables which express HEGIS (Higher Education General Information Survey) taxonomy terms as sets of LC (Library of Congress) class numbers; (2) the use of these tables to compare library…

Complex View Support for a Library Database System.
Peer reviewed Peer reviewed
Nishimoto, Hideki; Ura, Shoji – Information Processing and Management, 1989
Describes an interface mechanism called "complex view support" to be used with a relational database system (RDBS) in supporting increasingly complex distributed environments in automated library systems. The interface system refers queries to multidimensional tables as well as to flat tables on RDBS and is shown to efficiently support…

A Hyperknowledge Framework of Decision Support Systems.
Peer reviewed Peer reviewed
Chang, Ai-Mei; And Others – Information Processing and Management, 1994
Presents a hyperknowledge framework of decision support systems (DSS). This framework formalizes specifics about system functionality, representation of knowledge, navigation of the knowledge system, and user-interface traits as elements of a DSS environment that conforms closely to human cognitive processes in decision making. (Contains 52…

Experiments in Automatic Library of Congress Classification.
Peer reviewed Peer reviewed
Larson, Ray R. – Journal of the American Society for Information Science, 1992
Presents the results of research into the automatic selection of Library of Congress Classification numbers based on the titles and subject headings in MARC records from a test database at the University of California at Berkeley Library School library. Classification clustering and matching techniques are described. (44 references) (LRW)
