Discusses hypermedia as an appropriate medium for supporting collaborative work and describes hypermedia systems in general and NoteCards in particular. Experiences of collaborators working with NoteCards are presented, the resulting development of two tools is described, and future developments for NoteCards and these tools are discussed. (17…

Discusses the design and implementation of database management systems for low-organized and natural language text on small computers. Emphasis is on the efficient storage and access of primary (text) and secondary (dictionary) files. Possible expansions to the system to increase its use in linguistic research are considered. (six references)…

Discusses the role of hypertext as a communications medium and factors that must be considered in hypertext design and applicability. Implications of the division of labor in knowledge work and for our conception of literacy are addressed. (MES)

This updated bibliography on information retrieval covers the period from late 1986 through mid-1988. The 1,059 references are organized in 11 subject sections. Author and permuted title indexes are included. (MES)

Discussion of natural language processing components of information retrieval systems focuses on a full-text system called TOPIC (Text-Oriented Procedures for Information Management and Condensation of Expository Texts) that is based on text parsing. Highlights include design rationales for semantic parsing; text coherence; and a semantic model of…

This overview outlines important databases providing relevant articles and information for professionals conducting research in the fields of blindness and disability. (Author/DB)

This introduction to a special issue devoted to modeling data, information, and knowledge briefly describes the origins of the papers presented and the topics covered, which include: Boolean logic; probability theory; artificial intelligence; organizing and encoding information and data; and characteristics of users of retrieval systems. (12…

Investigates the role of information retrieval in the enhancement from database management to knowledge base management and considers the relationship between information retrieval and artificial intelligence. Highlights include unstructured databases; storage of internal forms of documents; an example with relational database operations; and…

Explains aspects of an Internet gopher developed by the National Institute of Standards and Technology's (NIST) Standard Reference Data (SRD) program. The gopher lists SRD projects and data centers and enables users to find and contact the researchers associated with these projects. Delivery of scientific information is also discussed. (LRW)

A theoretical framework of working memory is proposed in which cognitive processes are viewed as a sequence of stable states representing end products of processing. In skilled activities, acquired memory skills allow these end products to be stored in long-term memory and kept accessible through short-term memory retrieval cues. (SLD)

Discussion of information retrieval focuses on theoretical and empirical advances in knowledge-based information retrieval. Topics discussed include the use of natural language for queries; the use of expert systems; intelligent tutoring systems; user modeling; the need for evaluation of system effectiveness; and examples of systems, including…

Results of investigations into associative priming are summarized and the relative strengths of spreading activation and nonspreading activation theories of priming are assessed. The explanatory power of spreading-activation theories is at least as great as that of nonspreading-activation theories. (SLD)

Distinguishes between document-oriented and user-oriented indexing and discusses the advantages and disadvantages of request-oriented and automated indexing. Request-oriented indexing is difficult to implement with human, a priori indexing. Automated indexing can be tailored to individual requests, but most research in this area focuses on global…

Describes Z39.50, a standard prepared by the National Information Standards Organization (NISO) for information retrieval that allows two computer systems connected to a network to exchange messages for the purpose of searching databases and receiving records. Canada's involvement is discussed, and possible library applications are described. (LRW)

Reports on the validity of the Multiple Poisson (nP) model of word distribution in full-text document collections. A practical algorithm for determining whether a certain word is distributed according to an nP distribution and the results of a test of this algorithm in three different document collections are described.
