Presents and discusses implications of a set of measures of information. Definitions of relevant terms, including fact, data, representation, information, and knowledge, are given; four levels of processing data are explained (i.e., data transfer, data selection, data analysis, and data reduction); and relationships between information and…

These two articles introduce a new model of probablistic information retrieval (PIR) that is based on the statistical technique of the combination of expert opinion (CEO), which in this model is the opinions of indexers and users. Part 1 presents the conceptual basis, while Part 2 explains the mathematical details. (73 references) (LRW)

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…

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.

Describes a study of 11 large firms that identified difficulties that organizations encounter in matching current information technologies with business needs. The main problems are discussed, including high costs of new technology, lack of computer literacy among senior management, and lack of time in the information systems department. (Contains…

Two studies of the cognitive processes involved in online document-based information retrieval were conducted. These studies led to the development of five computational models of online document retrieval which were incorporated into the design of an "intelligent" document-based retrieval system. Both the system and the broader implications of…

Built using a distributed architecture, this prototype distributed information retrieval system uses statistical ranking techniques to provide better service to the end user. Distributed architecture was shown to be a feasible alternative to centralized or CD-ROM information retrieval, and user testing of the ranking methodology showed both…
