Proposes a microprocessor-based architecture that makes large use of parallelism both in processing and in retrieval operations. The proposed system consists of three functional blocks: the query processor, simple query executers, and the answer composer. Twenty-one references are listed. (FM)

Describes an online microcomputer-based system called Reference Librarian Enhancement System (REFLES) which stores factual information. Examples of data in the system and uses of the service are presented, as well as considerations for the future. Twelve (12) references are included. (Author/BK)

Discusses the potential of recent work in artificial intelligence, especially expert systems, for the development of more effective information retrieval systems. Highlights include the role of an expert bibliographic retrieval system and a prototype expert retrieval system, PROBIB-2, that uses MicroProlog to provide deductive reasoning…

Describes the construction (input preparation, computer processing, and presentation) of Classaurus, a vocabulary control tool used for indexing according to the Postulate-based Permuted Subject Indexing (POPSI) language. The efficiency of an online classaurus with facilities for direct accessing and updating is discussed. (MBR)

Describes three major features of treatment of paradigmatic thesaural information in microcomputer-based concept network management system: use of simple graphic displays of thesaural or paradigmatic information (linktypes); use of thesaural information to generate indirect entries; capability of customizing index displays, including thesaural…

Describes Reflink, a system based on sophisticated information retrieval techniques which is housed in a small microcomputer, and its predecessor, Reference Librarian Enhancement System (REFLES). The systems are placed in a conceptual framework involving stable and dynamic information, and several illustrations of multiple uses are presented. Four…

Describes a microcomputer software system designed at British Library which will interface with existing BLAISE services; e.g., offline editing of records retrieved online, stored search, and data preparation facilities. A technical description, features of system, applications programs, and the CORTEX interface with the mainframe system are…

Describes two experiments that were conducted at the University of Illinois to determine how cognitive abilities of users of information retrieval systems and specific design features combine to create system usability. Logical reasoning and perceptual speed are examined, and reliability and validity are discussed. (Contains 12 references.) (LRW)
