Discusses the probabilistic nature of information retrieval, and describes a front end system designed to permit searchers to attach probabilistically interpreted weights to query terms, which could be adapted for conventional information retrieval systems without requiring radical changes in current indexing procedures. (37 references) (CLB)

Provides an overview of methods for improving the effectiveness of Boolean retrieval systems, including document clustering, relevance feedback, weighted term searching, ranked output, and fuzzy set theory. The discussion of experimental studies with the SMART and SIRE systems focuses on the implementation and results of these methods. (69…

This paper reviews the services provided by the ERIC system and suggests ways to broaden its scope through coordination with other existing education databases. The first of four major sections chronicles the evolution of ERIC and explains why it has not been able to exercise true bibliographic control over the literature of education. The second…

Presents a new model of searching in online and other information systems, and reviews the literature of manual information seeking behavior for suggestions of capabilities users might like in online systems. Based on the model--called "berrypicking"--and research, suggestions are made for how new search capabilities could be implemented…

Discusses the advantages of maintaining local numeric databases, and describes the activities involved in creating a local database. The acquisition of files, user support, data storage and access, database management, costs, and planning strategies are discussed. (5 notes with references) (CLB)

Identifies two types of applications software for microcomputers: (1) communications, file transfer, and search assistance software, which facilitates intelligent access to external databases; and (2) software to support local database creation and searching. Functions of each type of software are described and examples of commercial packages are…

Describes a pilot project by the University of California to provide access to biomedical and health sciences literature through the integration of the MEDLINE database into the University's MELVYL online union catalog. The discussion covers the design, implementation and evaluation of the system, current planning efforts, and key technical and…

Reviews developments and products in the information industry that are aimed at the end user and identifies impediments to end user searching that may explain why end user access has not supported these products. Suggestions for overcoming these impediments are offered. (eight references) (CLB)

An automated library routine management system was developed in-house to create system unique to the Library and Information Center, Lunar and Planetary Institute, Houston, Texas. A modular approach was used to allow continuity in operations and services as system was implemented. Acronyms and computer accounts and file names are appended.…

Eleven articles introduce expert systems applications in library and information science, and present design and implementation issues of system development for reference services. Topics covered include knowledge based systems, prototype development, the use of artificial intelligence to remedy current system inadequacies, and an expert system to…

Discusses the issues influencing the design, implementation, and promotion of the Towers Perrin in-house text retrieval system. The discussion of factors influencing system design includes the organizational culture, the existing computer and communications network, and the availability of text retrieval software. Suggestions for in-house systems…

Describes the development of a bibliographic information system designed to assist architecture/engineering firms under contract to the Army Corps of Engineers in locating regulations or guidelines for the planning, design, or construction of army facilities. A sample search of the system is appended. (Author/CLB)

The first of two papers describes the rewriting of the DIALOG system software for DIALOG Version 2, and discusses both software and user interface issues. The second describes the development of Canadian produced scientific and technical databases and discusses issues concerning user training. (CLB)

Discusses the motivation for integrating information retrieval and database management systems, and proposes a probabilistic retrieval model in which records in a file may be composed of attributes (formatted data items) and descriptors (content indicators). The details and resolutions of difficulties involved in integrating such systems are…

Describes the development of a machine readable reference information file at the University of California at Los Angeles. The discussion covers factors affecting the database structure, the use of a sophisticated text management system to enter data onto microcomputers, and possible future implementations of the reference information system.
