Formal Specification of Information Systems Requirements.
Peer reviewed Peer reviewed
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)

End-User Information-Seeking in the Energy Field: Implications for End-User Access to DOE/RECON Databases.
Peer reviewed Peer reviewed
Case, Donald; And Others – Information Processing and Management, 1986
The U.S. Department of Energy (DOE) software research and development project described explores information seeking behavior of end-user energy experts and develops software offering tutorials on front-end use of DOE/RECON databases and active help in performing online searches. Software development is described and results of prototype testing…

On the Value of Information in System Design: A Framework for Understanding and Aiding Designers.
Peer reviewed Peer reviewed
Rouse, William B. – Information Processing and Management, 1986
Discusses what designers do, information they need, and how they might be aided, as background information for developing useful computer-aided decision systems to enhance designers' productivity. It is concluded that effectiveness of computer-assisted design systems depends on the value of the information and the flexibility of the support they…

Retrieval Hierarchies in Hypertext.
Peer reviewed Peer reviewed
Rada, Roy; And Others – Information Processing and Management, 1993
Describes a collaborative, reuse hypertext system, called MUCH (Many Using and Creating Hypertext). The novel browsing and retrieval characteristics of the system are based on a semantic net connecting documents, thesauri, and discussions. Word patterns are documented for reuse, creating and reorganizing network traversal according to user…

Semantics of User Interface for Image Retrieval: Possibility Theory and Learning Techniques.
Peer reviewed Peer reviewed
Crehange, M.; And Others – Information Processing and Management, 1989
Discusses the need for a rich semantics for the user interface in interactive image retrieval and presents two methods for building such interfaces: possibility theory applied to fuzzy data retrieval, and a machine learning technique applied to learning the user's deep need. Prototypes developed using videodisks and knowledge-based software are…
