Peer reviewedNishimoto, 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…

Peer reviewedOstroff, Daniel; Shneiderman, Ben – Information Processing and Management, 1988
Describes a study that measured the speed, error rates, and subjective evaluation of arrow jump keys, a jump mouse, number keys, and a touch screen in an interactive encyclopedia. The results of previous studies are discussed as well as the findings of this study. Improvements in selection devices are suggested. (41 references) (Author/CLB)

Peer reviewedSrinivasan, Padmini – Information Processing and Management, 1989
Describes rough sets theory and discusses the advantages it offers for information retrieval, including the implicit inclusion of Boolean logic, term weighting, ranked retrieval output, and relevance feedback. Rough set formalism is compared to Boolean, vector, and fuzzy models of information retrieval and a small scale evaluation of rough sets is…

Peer reviewedSalton, G. – Information Processing and Management, 1988
Describes a new Boolean retrieval environment in which an extended soft Boolean logic is used to automatically construct queries from original natural language formulations provided by users. Experimental results that compare the retrieval effectiveness of this method to conventional Boolean and vector processing are discussed. (27 references)…

Peer reviewedFox, Edward A.; Koll, Matthew B. – Information Processing and Management, 1988
Provides an overview of methods for improving the effectiveness of Boolean retrieval systems, including document clustering, relevance feedback, weighted term searching, ranked output, and fuzzy set theory. The discussion of experimental studies with the SMART and SIRE systems focuses on the implementation and results of these methods. (69…

Peer reviewedMenou, Michael J. – Information Processing and Management, 1985
Describes information system being developed by Unesco's General Information Program and Brazilian Institute for Information Science and Technology to overcome lack of timely, relevant data to support national information decision making. Principles and examples of practical applications of the system are presented. Prospects and requirements for…
