Presents specifications for software that is designed to support manual development and maintenance of information retrieval thesauri. Evaluation of existing software and design of custom software is discussed, requirements for integration with larger systems and for the user interface are described, and relationships among terms are discussed.…

This last article in a series which reported results of a software evaluation project done by the Netherlands Association of Users of Online Information Systems (VOGIN) focuses on how to select appropriate software. Topics discussed include price considerations; user needs; and types and quality of information. (Contains 11 references.) (LRW)

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.…

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)

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)

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…

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 the use of thesauri in automatic indexing and describes the development of a prototype computerized abstractor's assistant. Topics addressed include TEXNET, a text network management system; the use of TEXNET for abstracting; the structure and use of a thesaurus for abstracting in TEXNET; and weighted terms. (Contains 26 references.)…

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. (LRW)

Describes some of the problems encountered in full text searching and suggests ways to overcome them. Areas discussed include differences between online and offline versions of full text; lack of precise and flexible indexing; software inadequacies; record displays; typographical errors; and problems with both global and source searching.
