The Cobb-Douglas model applied to value added as a function of labor, capital, purchases of information services, and purchases of other input is used to investigate the use of information by the industrial sector of Croatia, Yugoslavia. It is concluded that less than an optimal amount of information resources is being used. (13 references)…

Describes a generic software tool, Objective-C, that detects and corrects data inconsistency in databases. In this study, heterogeneous bibliographic information is integrated by using the message-object model to implement data abstraction methodologies. Citation translation problems are discussed and future directions for research are suggested.…

Discussion of the interpretation of user queries in information retrieval highlights theoretical models that utilize user characteristics maintained in the form of a user profile. Various query/profile interaction models are identified, and an experiment is described that tested the relevance of retrieved documents based on various models. (29…

Discusses the problems of compressing a large textual database for storage on CD-ROM. A text-compression algorithm is presented, new algorithms for compression of indices are described, and the ARTFL (American and French Research on the Treasury of the French Language) database is used as an example. (14 references) (LRW)

Illustrates that the Poisson-lognormal model provides good fits to a diverse set of distributions commonly studied in bibliometrics and scientometrics. Topics discussed include applications to the empirical data sets related to the laws of Lotka, Bradford, and Zipf; causal processes that could generate lognormal distributions; and implications for…

Describes a study which focused on the application of magnitude estimation, an open-ended scaling technique developed in the field of sensory psychophysics, to the task of measuring relevance judgments. The discussion covers potential biases found in magnitude estimation and in commonly used category rating scaling processes. (23 references)…

Investigates applicability of inverted file processing in magnetic bubble memories by presenting four magnetic bubble memory models as storage mediums: one based on a major-minor loop configuration; one utilizing a decoder design on a magnetic bubble memory chip; and two based on different structural configurations of the first two. (MBR)

Describes a project aimed at developing a system to support managers of business software projects by incorporating knowledge acquisition and emphasizing the integration of the manager's tasks. The discussion covers the knowledge acquisition methodology, the architecture of an integrated system, and an overview of project management tasks. (15…

Discusses possibility of using expert systems to develop new model in cataloging theory made necessary by technological progress, rising user expectations, and economic pressures. A data structure for bibliographic information required by Anglo American Cataloging Rules, 2nd edition, (AACR2) is suggested, and possible heuristics for interpreting…

Discusses current use of psychological theory in software science and reviews recent developments in cognitive psychology relevant to programing (human information processing, expert-novice differences). Critique of Maurice Halstead's model of cognitive aspects of programing and a structured data flow perspective (control flow and data flow…

Formulates a model to accommodate the hypothesis that, if the content representation items of documents in a database are neither totally independent nor highly correlated, combining them in a certain way may increase information retrieval effectiveness. The results of a small experiment that tested this hypothesis are presented. (Author/JD)

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…

Presents an attempt to develop an integrated overall management information system growth and integration theory for small organizations. The three dimensions that facilitate information integration progress (i.e., electronic data processing evolution, computerized tools, and user types) are presented, analyzed, and characterized. Guidelines for…

Discusses the shift of information access from a data-centered to a user-centered model and describes the Daltext system, a prototype user-centered information system that allows the user to determine how the data will be viewed (i.e., within a datastream model, a set model, a relational model, and/or a hierarchical model). (Contains 30…

Reports information retrieval experiments comparing the performance of a probabilistic retrieval model that incorporates interdocument links with the simpler spreading activation strategy. Results indicated that the overall improvement obtained by including hypertext links in the retrieval model was low. (30 references) (EA)
