Martella, G.; Gobbi, G. – Information Processing and Management, 1981
Proposes a microprocessor-based architecture that makes large use of parallelism both in processing and in retrieval operations. The proposed system consists of three functional blocks: the query processor, simple query executers, and the answer composer. Twenty-one references are listed. (FM)

Watters, C. R.; Shepherd, M. A. – Information Processing and Management, 1987
Discusses the potential of recent work in artificial intelligence, especially expert systems, for the development of more effective information retrieval systems. Highlights include the role of an expert bibliographic retrieval system and a prototype expert retrieval system, PROBIB-2, that uses MicroProlog to provide deductive reasoning…

Teskey, F. N. – Information Processing and Management, 1989
Presents a model that distinguishes between data as directly observable facts, information as structured collections of data, and knowledge as methods of using information. The discussion covers the likely benefits of the use of the model for a semantic information retrieval system using the concept of semantic categories. (28 references)…

Danilowicz, Czeslaw – Information Processing and Management, 1983
Presents principles for determining profile of a system user based on analysis of co-occurrence of index terms in queries and pertinent documents. A procedure for determining index term weights, the information value of which depends on the degree of homogeneity of system users, is introduced. Three references are cited. (EJS)

Nath, Ravinder – Information Processing and Management, 1989
Describes a study that examined whether increased usage of computer based information systems (CBIS) results in improved end-user satisfaction. The results indicate that both the frequency of CBIS use and the proportion of total time spent using CBIS are positively correlated with end-user satisfaction. The implications for designing measures of…

Rybinski, Henryk; Szymanski, Boleslaw – Information Processing and Management, 1981
Discusses the multilevel information system (MLIS), a retrieval system that integrates functions typical for database management systems and retrieval-oriented systems and provides several levels of data accessing, each developed for a different class of users. Twenty-two sources are cited. (FM)

Bates, Marcia J. – Information Processing and Management, 1990
Examines various ways of dividing the labor of an information search between the person and the system. Different configurations of two dimensions--degree of system involvement in searching and types of search activity carried out by the person or system--are discussed. Recommendations for further research and development are offered. (49…

Yannakoudakis, E. J.; Fawthrop, D. – Information Processing and Management, 1983
This paper describes an intelligent spelling error correction system for use in a word processing environment. The system employs a dictionary of 93,769 words and, provided the intended word is in the dictionary, it identifies 80 percent to 90 percent of spelling and typing errors. Nine references are cited.

Chen, H.; And Others – Information Processing and Management, 1994
Reports on two empirical studies that examined the nature and causes of information management indeterminism in an online research environment. A knowledge-based design for alleviating indeterminism which contains a system-generated thesaurus and an inferencing engine is proposed. (Contains 63 references.) (JLB)

Cooper, David; Lynch, Michael F. – Information Processing and Management, 1984
Suggests new method of external distribution called tree partitioning that involves use of binary tree to split incoming file into successively smaller partitions for internal sorting. Number of disc accesses during a tree-partitioning sort were calculated in simulation using files extracted from British National Bibliography catalog files. (19…

Kampfner, Roberto R. – Information Processing and Management, 1985
Presents a formal model for specification of logical requirements of computer-based information systems that incorporates structural and dynamic aspects based on two separate models: the Logical Information Processing Structure and the Logical Information Processing Network. The model's role in systems development is discussed. (MBR)

Rao, V. Venkata; Zunde, Pranas – Information Processing and Management, 1982
Brief discussion of state-of-the-art of modeling complex information systems distinguishes between macrolevel and microlevel modeling of such systems. Network layout and hierarchical system models, simulation, information acquisition and dissemination, databases and information storage, and operating systems are described and assessed. Thirty-four…

Forgionne, Guisseppi A. – Information Processing and Management, 1988
Presents an organizational strategy for effective delivery of required computer technology to management. The nature of the technology is identified, the relationship between technology and information resources management is examined, and the shortcomings of traditional systems approaches are discussed.

Hawkins, Donald T. – Information Processing and Management, 1985
Current awareness services at AT&T Bell Laboratories are described: bulletins announcing over 80,000 externally published items/year; production of four commercial machine-readable databases and camera-ready bulletin copy by Bell Laboratories Publication, Alerting, and Retrieval System (BELLPAR); photocopy service. Improvements in service are…
