Presents model of algorithm design (activity in software development) based on analysis of protocols of two subjects designing three convex hull algorithms. Automation methods, methods for studying algorithm design, role of discovery in problem solving, and comparison of different designs of case study according to model are highlighted.…

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.…

Describes the Case Hierarchy, a model of the case system of unconstrained natural language, and ways in which the case system is specialized in a restricted domain. Results of a feasibility study which examined the utility of the Case Hierarchy and the Case Hierarchy Tool (an intelligent editor supporting the domain analysis process) are…

This description of the development of expert systems designed to solve management problems focuses on the issue of corporate divestment as an example. Software needs are discussed, and an example of a management expert system for divestment analysis at James Madison University is briefly described. (Author/LRW)

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 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…

Library usage study of OCLC network-provided software and services indicates most users make local modifications to standard practices. Findings are discussed in terms of network models for decision making in software use; methodology of software user studies; and diffusion of innovation processes in postimplementation stages of transaction…

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…
