Reviews what information and software sciences have thus far accomplished in search for empirical regularities and laws and examines what theories have been developed to explain and account for regularities and laws. Specific laws and theories of information highlighted are those of Zipf, Bradford, Lotka, Mandelbrot, and Simon. (Forty references)…

Summarizes various linguistic approaches proposed for document analysis in information retrieval environments. Topics discussed include syntactic analysis; use of machine-readable dictionary information; knowledge base construction; the PLNLP English Grammar (PEG) system; phrase normalization; and statistical and syntactic phrase evaluation used…

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.…

Discusses the interpretation of nominal compounds in the context of natural language processing for information retrieval. Knowledge-intensive algorithms that can successfully interpret compounds found in technical documents are described, and experiments are reported that indicate these algorithms may be unnecessary for improving retrieval…

Discusses methods of textual documentation that can be used for software documentation. Highlights include measurement of text comprehensibility; methods for the measurement of documentation quality, including readability and the Cloze Procedure; tools for the measurement of text readability; and the development of the Reading Measurability…

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…

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…

Examines current activities in subject analysis of large bibliographic databases to assist database managers in making cost-effective decisions. Issues addressed include manual indexing aids, automatic indexing, and connecting indexing terms. Several software packages are described, and future research directions are suggested. (58 references)…

This paper reviews the progress made so far in the development and use of expert systems for library and information services in the areas of online information retrieval, including gateway software and intelligent front-ends; cataloging, including bibliographic utilities and machine-aided cataloging; abstracting; reference work; and indexing and…

Description of a Canadian research and development project that involved the development of a library information system which would satisfy the needs of a variety of libraries focuses on the technological aspects of the system. Data manipulation is discussed, software is described, standards are considered, and customer requirements are examined.…
