The semantic web or Web 3.0 makes information more meaningful to people by making it more understandable to machines. In this article, the author examines the implications of Web 3.0 for education. The author considers three areas of impact: knowledge construction, personal learning network maintenance, and personal educational administration.…

Describes the inability of traditional subject index terms to represent relational information among concepts, and the development of frame based knowledge representation methods that provide relational semantic representations of documents and user queries. The discussion covers research in user interfaces and automatic document classifications,…

Reports preliminary results of a research project that investigated the effectiveness of a new technique for information retrieval interfaces called colinked descriptors, based on the concept of cocited references in the field of bibliometrics. Examples of colinked descriptors from the "Thesaurus of ERIC Descriptors" are presented.…

Unlike conventional information retrieval systems, natural language processing (NLP) systems translate queries automatically into the language of the system. This paper discusses the potential impact of NLP on both the indexing and retrieval of text and examines some current NLP projects and systems that have established knowledge bases in narrow…

Discusses the impact of research in artificial intelligence and human computer interaction on the design of bibliographic information retrieval systems, and presents design principles of a prototype system that uses semantically based searches and a knowledge base consisting of conceptual frames. (10 references) (CLB)

Discusses the design of interfaces for online systems and suggests requirements that must be met to offer maximum aid to inexperienced users. Highlights include the online search process, user data, query processing, database descriptors, semantic links, multilingual processing, search strategies, and distributed systems. A 20-page bibliography…

Describes the components and capabilities of expert systems, discusses the use of such systems in library information applications, and outlines research being done in this area. A project aimed at the development of an expert system for referral services is described in detail, and implications for future research are discussed. (CLB)

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)

Individual papers discussing various facets of human relationships with interactive computer systems present an analysis of direct manipulation interfaces; discuss notion of conceptual models shared by system and user and propose a design methodology for delivering models to users; and address the intelligibility of systems and importance of…

Identifies problems that undergraduate searchers encountered in a search of the ERIC database on CD-ROM. Results of participant observation, questionnaires, and interviews are reported; a taxonomy of user problems is proposed that includes syntactic errors and semantic errors; and recommendations for menu selection systems, online help, and…
