Discusses the feasibility of building intelligent rule- or weight-based algorithms into general-purpose software for interactive thesaurus navigation. Previous research is surveyed; practical investigations in thesaurus navigation and query enhancement are described; and implications for automatic or intelligent thesaurus navigation are…

Describes the design of a classification scheme for reusable software and the implementation of an information retrieval system for reusable software using the SMART system. Highlights include a review of other systems for reusable software; system design; reorganization of software documentation; and system testing, including recall and…

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…

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.…

Explores potential of mathematical theory of communication for information science and examines question of how to encode a message at time it is encountered for subsequent recall. Examples of problem, a prototype computer program and experiment, coding as embedding in associational nets, and nature of information are discussed. (Nine references.)…

Discussion of electronic image processing focuses on the need for indexing to ensure adequate retrieval. Highlights include icons, i.e., reduced pictorial surrogates; file staging; indexing languages, including examples of thesauri; and pictorial languages, including a HyperCard system. (Contains eight references.) (LRW)

In the last issue, this journal asked a question on many librarians' minds, and it was pleased with the depth and variety of responses. As suggested by this journal editorial board member Oliver Pesch, readers were asked, "Many libraries have gone to federated searching to win users back from Google. Is it working?" Respondents approached the…

Reviews the conceptual foundations of hypertext as developed by Vannevar Bush and discusses current applications of hypertext as information vision, database technique, and computer user interface. Criticisms of this indexing technique, its technological limitations, and possible future applications are discussed. (two references) (CLB)

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 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)

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)

Discusses design, applications, advantages, disadvantages, users, and future trends of two types of natural language programs: menu-driven where commands are constructed from lists of words, and English-command-driven which translate your words into commands recognized by the computer. Several specific computer programs are described, including…

This review of public domain software (written by individuals who release programs for free copying and distribution) focuses on disk utility programs which deal with the manipulation of files on disks (finding, moving, changing, viewing, organizing, storing). Sources for identifying programs and three addresses for software distribution are…

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 CD-ROM and its use as a new form of instructional technology. Topics discussed include the role of software in searching databases; benefits of CD-ROM over traditional materials; the need for adequate instruction on searching, including examples of necessary skills for effective searching; and guidelines for search strategies.
