Discussion of the notion of readability focuses on predicting readability with computerized readability formulas. Semantic and syntactic factors are discussed, the development of readability formulas is described, and five commercially available computer readability formulas are reviewed, including the Readability Estimator, Readability Formulas,…

Describes the Constituent Object Parser (COP), a domain independent syntactic parser developed for use in information retrieval and similar applications. The syntactic structure of natural language entities is discussed, and the mechanisms by which COP handles the problems of conjunctions, ellipsis, and discontinuous constituents are explained.…

This article argues for the development of a framework through which to describe children's multimodal texts. Such a shared discourse should be capable of including different modes and media and the ways in which children integrate and combine them for their own meaning-making purposes. It should also acknowledge that multimodal texts are not…

Examines problems encountered when setting up a hypertext link, called an identity link, for moving between bibliographic and full text databases. MEDLINE and CCML (Comprehensive Core Medical Library) are used as examples, BRS/SEARCH text retrieval software is explained, and problems with syntax are discussed. (two references) (LRW)

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…

Discusses problems encountered with the syntactic analysis of free text documents in indexing. Postcoordination and precoordination of terms is discussed, an automatic indexing system call COPSY (context operator syntax) that uses natural language processing techniques is described, and future developments are explained. (60 references) (LRW)

Discussion of problems in computer assisted instruction focuses on poorly written software and the role of computer programing. Use of computers without programing knowledge is discussed, and pragmatics is emphasized as the discipline needed to supplement syntax and semantics in the field of computer science. (seven references) (LRW)

Noting that expert computer systems respond to various contexts in terms of knowledge representation, this paper explains that heuristic rules of production, procedural representation, and frame representation have been adapted to such areas as medical diagnosis, signal interpretation, design and planning of electrical circuits and computer system…

Describes the development of a software system, SIMPR (Structured Information Management: Processing and Retrieval), that will process documents by indexing them and classifying their subjects. Topics discussed include information storage and retrieval, file inversion techniques, modelling the user, natural language searching, automatic indexing,…

Describes principles underlying ILLICO, a generic natural-language software tool for building larger applications for performing specific linguistic tasks such as analysis, synthesis, and guided composition. Shows to what extent this approach is relevant to the development of computer-assisted language-learning systems. (Author/VWL)

Compares artificial intelligence and information retrieval paradigms for natural language understanding, reviews progress to date, and outlines the applicability of artificial intelligence to question answering systems. A list of principal artificial intelligence software for database front end systems is appended. (CLB)
