Describes a new graphical method of storing and retrieving concept relations of various kinds. (Author/PF)

A brief history of bibliographic activities of the U.S. Geological Survey, including development of a computerized publishing system is given. Also described is the design of the bibliographic search system, application of the Generalized Information Processing System (GIPSY) to storage and retrieval of earth sciences literature, and preliminary…

The Clinical Documentation Section of Schering Corporation's Medical Information Center has developed an automated document storage and retrieval system capable of generating indexes to all documents in the system, summaries, and reports for management by computer. (MF)

Highlights the advantages of using holography for information storage, character recognition, file security systems, and other applications. (FM)

An algorithm is proposed to solve the problem of sequential indexing which does not use any grammatical or semantic analysis, but follows the principle of emulating human judgement by evaluation of machine-recognizable attributes of structured word assemblies. (Author)

The authors advocate a systematic procedure involving the identification of: fixed parameters, variable options for each variable parameter, factors affecting a choice among available options, factors affected by a choice among available options, and the optimum sequence in which decisions should be made during the design process. (Author/MF)

The main conclusions are: the human factor appears to be the main variable in all components of an information retrieval system; length of indexes affects performance considerably more than indexing languages; question analysis and search strategies affect performance to a great extent - as much, if not more than indexing. (Author/MF)

Reviews the state of information technologies involving teletext, viewdata, interactive graphics, videodisc, audio synthesis, and holography, and discusses the current understanding of access schemes and cognitive processing. Sixteen suggested readings and nine references are cited. (FM)

Describes the utility and applications of information retrieval thesauri and the development of the thesaurus for the DISCLOSURE data base. (PF)

Proposes a new conceptual basis for visualizing the organization of information, or knowledge, which differentiates between the concept "vectors" for a field of knowledge represented in a multidimensional space, and the state "vectors" for a person based on his understanding of these concepts, and the representational…

The direct-chaining technique of hash coding is generalized in a manner that is useful for storing records on the basis of non-unique search keys. Two hash functions are used, a process implying a tree structure. Two models, one involving unique and the other non-unique keys, are presented. (7 references) (Author/KE)

Methods to improve bringing the ERIC knowledge base to the attention of practitioners emphasizing the use of informal communication are suggested. (NH)

A new technique, known as discrimination value analysis, ranks the text words in accordance with how well they are able to discriminate the documents of a collection from each other. (Author/PF)

Defines a hash coding model for non-unique search keys and derives the expected number of accesses needed to retrieve all desired records from a computer storage device. (Author)

Proposes a solution to the problem of loading repetitive bibliographic information in a microcomputer-based relational database management system. The alternative design described is based on a representational redundancy design and normalization theory. (12 references) (Author/CLB)
