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…

Following a discussion of derivative versus assignment indexing, use of roles, and concept behind Preserved Concept Indexing System, features of PERMDEX (microcomputer program to assist in creation of permuted printed index) are described including indexer input and prompts, the shunting algorithm, and sorting and printing routines. Fourteen…

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…

Analyzes computer terminal memory performance in terms of overflow probability and average queueing delay, and presents new method to derive a closed expression for data arrivals with Erlangly distributed interarrival times and an approach to derive steady state probability expressions of the terminal memory content process. Twenty references are…

Presents a system model for transmission of input data that is coming from terminals of users in a limited user resource-sharing environment. Performance of a mini/microcomputer receiving mixture of picture-phone terminal data is analyzed with constant service times, synchronous transmission, and single-server interruptions through first-order…

Describes study of manual and experimental automated circulation systems in a university library in Nigeria. Data were collected for eight circulation activities in order to calculate the direct labor costs of circulating a book on each system. Automated system's book circulation costs were higher although direct labor costs were less. (MBR)
