    Abstract
    Discusses the need for facilities for online vocabulary control and standardization of terms, codes, etc., so as to secure consistency in naming of subjects, objects, countries, languages, etc., in databases at data entry stage. Most information storage and retrieval packages for microcomputers including MicroIsis provide for online vocabulary control in formulating search expressions for information retrieval, but not at the data entry stage. VOCON.PAS is a Pascal interface program for use with MicroIsis software for (a) online selection of term(s) and/or code(s) from vocabulary control tool, such as, thesaurus, subject heading list, classification scheme, nomenclature list(s)

    Abstract
    Natural Language Processing (NLP) is an area of research and application that explores how computers can be used to understand and manipulate natural language text or speech to do useful things. NLP researchers aim to gather knowledge an how human beings understand and use language so that appropriate tools and techniques can be developed to make computer systems understand and manipulate natural languages to perform desired tasks. The foundations of NLP lie in a number of disciplines, namely, computer and information sciences, linguistics, mathematics, electrical and electronic engineering, artificial intelligence and robotics, and psychology. Applications of NLP include a number of fields of study, such as machine translation, natural language text processing and summarization, user interfaces, multilingual and cross-language information retrieval (CLIR), speech recognition, artificial intelligence, and expert systems. One important application area that is relatively new and has not been covered in previous ARIST chapters an NLP relates to the proliferation of the World Wide Web and digital libraries.

    Abstract
    The Internet and related information services attract increasing interest from information retrieval researchers. A survey of recent publications shows that frequent topics are the effectiveness of search engines, information validation and quality, user studies, design of user interfaces, data structures and metadata, classification and vocabulary based aids, and indexing and search agents. Current research in these areas is briefly discussed. The changing balance between CD-ROM sources and traditional online searching is quite important and is noted

    Abstract
    Farradane's theory of relational analysis has wide applications in information retrieval. The major areas of application cover their use in retrospective searches, semantic analysis of information, concept organisation and control, efficiency as an information retrieval tool, multilingual indexing tool, in SDI term relations in thesauri, study of nature of subjects, computerised indexing systems, analysis and measuring of information and organisation of current information. Most of the applications were in scientific subjects and the data bases considered were too small to generalise. Suggests 5 new areas of research on relational indexing: compilations of a detailed manual; application in scientific, social sciences, and humanities literature; application in study of the nature of subject literature; comparative efficiency of relational indeximg; and a compilation of a relational thesaurus.

    Abstract
    Discusses the issues involved in the development of data formats for computerized information retrieval systems. Integrated databases capable of holding both bibliographic and factual information, in a single database structure, are more convenient for searching and retrieval by end users. Several bibliographic formats have been developed and are used for these bibliographic control puposes. Reviews features of 6 major bibliographic formats: USMARC, UKMARC, UNIMARC, CCF, MIBIS and ABNCD are reviewed. Only 2 formats: CCF and ABNCD are capable of holding both bibliographic and factual information and supporting the design of integrated databases. The comparison suggests that, while CCF makes more detailed provision for bibliographic information, ABNCD makes better provision for factual information such as profiles of institutions, information systems, projects and human experts

    Abstract
    Design aspects of bibliographic databases are of utmost importance for effective resource sharing and for providing better information retrieval services in libraries. Standard formats such as the Common Communication Format (CCF) may be adapted for the design of databases. Experience shows that some modifications to the CCF format may be more useful for manipulation of data for various libray operations. Proposes the design of a bibliographic database based on CCF for use in Micr-CDS/ISIS. Almost all the mandatory CCF fields have been adopted and a few new fields added for achieving better results. Formats for display of records conform to AACR2. Provides ample catalogue entries and sample indexes to illustrate how the proposed design helps perform various information retrieval operations in libraries. Modifications in the display of records may be achieved with little effort
