Nageswara Rao, S. V.; And Others – Information Processing and Management, 1985
Discusses properties of multiple attribute tree (MAT) and inverted file structures; establishes suitability of MAT data structure for bibliographic files using worst-case performance measures; provides arguments to establish MAT average case superiority; and proposes an efficient adaptation of MAT data structure to exploit special features of MAT…
Descriptors: Algorithms, Comparative Analysis, Data Processing, Databases

Danilowicz, Czeslaw – Information Processing and Management, 1994
Discusses end-user searching in Boolean information retrieval systems considers the role of search intermediaries and proposes a model of user preferences that incorporates a user's profile. Highlights include document representation; information queries; document output ranking; calculating user profiles; and selecting documents for a local…
Descriptors: Algorithms, Comparative Analysis, Databases, Information Retrieval

Wilbur, W. John; Coffee, Leona – Information Processing and Management, 1994
Compares two methods of information retrieval--one that rates documents according to a query and another that uses relevant documents to find further relevant documents (i.e., neighboring documents). Highlights include experiments at the National Library of Medicine; feedback; vector cosine retrieval; and a measure of retrieval effectiveness…

Chen, Zhengxin – Information Processing and Management, 1993
Describes a conceptual model for integrating short scientific texts, which extends classical text storage and retrieval. A brief comparison with related approaches such as case-based reasoning and classification-based reasoning is also provided. (13 references) (Author/KRN)

Cooper, Randolph B. – Information Processing and Management, 1988
Organizes, describes, and evaluates management information systems research from 1981 to 1985 to provide an understanding of what constitutes management information systems research and to indicate areas for future research. (210 references) (Author/CLB)
Descriptors: Comparative Analysis, Decision Making, Evaluation Criteria, Literature Reviews

Wong, Wai Yee Peter; Lee, Dik Lun – Information Processing and Management, 1993
Discussion of search strategies in information retrieval systems focuses on the implementation of document ranking based on inverted files. Highlights include descriptions of three heuristic methods for implementing a weighting strategy and a comparison of two methods for estimating retrieval accuracy, including document movement and linear…

Rousseau, Ronald – Information Processing and Management, 1994
Discussion of informetric distributions shows that generalized Leimkuhler functions give proper fits to a large variety of Bradford curves, including those exhibiting a Groos droop or a rising tail. The Kolmogorov-Smirnov test is used to test goodness of fit, and least-square fits are compared with Egghe's method. (Contains 53 references.) (LRW)

Doreian, Patrick – Information Processing and Management, 1994
Discusses the use of citation networks for constructing measures of the relative standing of journals in scientific journal-to-journal networks. Topics addressed include eigenvectors; measuring the standing of national scientific communities; and an empirical comparison of two measures of standing, one considering the environment and one without…

Doreian, Patrick – Information Processing and Management, 1988
Presents a measure of the relative standing of professional journals in an aggregated journal citation matrix. The results of the application of the measure to a network of geographic journals during two time periods are reported and discussed. (35 references) (Author/CLB)

Eastman, Caroline M. – Information Processing and Management, 1988
Summarizes the similarities between classification systems for catalog selection and information retrieval systems, and discusses system characteristics that allow the use of measures such as recall and precision in system evaluation. (27 references) (Author/CLB)
Descriptors: Classification, Comparative Analysis, Evaluation Criteria, Evaluation Methods

Oberhofer, Cecilia M. A. – Information Processing and Management, 1993
Discussion of the use of scientific information disseminated in primary subject literature focuses on a study that developed a methodology for hypothesis testing that measured document obsolescence by means of citation analysis and content obsolescence by expert opinions and then compared the results. Information validity and information utility…

Szabo, Jozsef; Dienes, Istvan – Information Processing and Management, 1988
Examines trends in labor and capital resources and the production of the information economy in Hungary, and compares them to trends experienced in other market-oriented countries. A model that considers regional differences in the demand, supply, and life cycle of goods is used to explain secular information sector changes. (Author/CLB)

Morrissey, J. M.; And Others – Information Processing and Management, 1986
Proposes a "Model of Querying" for users of office filing facilities and discusses its motivation, aspects, attributes, and advantages. A review of current information systems and attempts to combine information retrieval, artificial intelligence, and database management techniques leads to conclusion that no resultant system is adequate…
