Presents the state-of-the-art of information systems monitoring, addressing historical and current approaches and manual and automated techniques; develops the concept of automated monitoring into a well-defined methodology; formulates methodologies/techniques/theoretical foundations for analyzing monitored data; and discusses computer based…

Proposes a method for correcting spelling errors found in electronic documents which is derived from a logical analysis of the problem. Similarity relations and character string matching are discussed, the use of PROLOG is described, suggestions for further research are made, and a literature review is included. (47 references) (Author/LRW)

Discusses the United States economy and reviews National Income Accounting concepts and evidence about future of an information economy. It is concluded that information economy growth will be in products, not services, and that it will not continue at same rate it has in past. Thirty-six references are cited. (EJS)

Discussion of data quality examines five approaches to defining data in the literature; considers criteria of adequacy; proposes a modeling activity; discusses the most important dimensions of data quality, including accuracy, precision and reliability, currentness, completeness, and consistency; and suggests further research. (Contains 44…

Examines journal influence in communicating management information systems (MIS) research over a nine-year period using citation analyses, researcher perceptions, and publishing patterns of MIS research universities. A core group of MIS journals is identified, and ranking according to journal influence is discussed. (37 references) (LRW)

Describes a study that was conducted to explore the potential of text analysis as a tool in full-text search and design improvement. A review of pertinent literature is included, and a trial analysis performed in the domain of family history literature is described. (Contains 49 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 the linguistic phenomenon of anaphora; surveys the approaches to anaphora undertaken in theoretical linguistics and natural language processing (NLP); presents results of research conducted at Syracuse University on anaphora in information retrieval; and discusses the future of anaphora research in regard to information retrieval tasks.…

Describes and organizes the variables affecting display presentation format (i.e., tables and graphs) in information systems into a classification scheme and creates a framework for research in this area. Two-factor studies are discussed; research recommendations are presented; and Cognitive Match Interface Design is explained. (Contains 31…

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)

Discusses the need for knowledge gateway systems to provide access to scattered information and the use of technologies in gateway building, including artificial intelligence and expert systems, networking, online retrieval systems, optical storage, and natural language processing. The status of four existing gateways is described. (20 references)…

Review of office filing facility filing and retrieval mechanisms for unstructured and mixed media information focuses on free text methods. Also discussed are the state of the art in handling voice and image data, problems with searching text surrogates to implement free text content retrieval, and work of Project Minstrel. (Author/MBR)

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…

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)

Identifies a set of objects that is genuinely indigenous to management information systems and constructs a simple model based on them. The model's four basic entities, which define the scope of information theory, are data, information, knowledge, and wisdom. (Contains 46 references.) (KRN)
