    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)

    1. Introduction Web search engines and digital libraries usually expect the users to use search terms that most accurately represent their information needs. Finding the most appropriate search terms to represent an information need is an age old problem in information retrieval. Keyword or phrase search may produce good search results as long as the search terms or phrase(s) match those used by the authors and have been chosen for indexing by the concerned information retrieval system. Since this does not always happen, a large number of false drops are produced by information retrieval systems. The retrieval results become worse in very large systems that deal with millions of records, such as the Web search engines and digital libraries. Vocabulary control tools are used to improve the performance of text retrieval systems. Thesauri, the most common type of vocabulary control tool used in information retrieval, appeared in the late fifties, designed for use with the emerging post-coordinate indexing systems of that time. They are used to exert terminology control in indexing, and to aid in searching by allowing the searcher to select appropriate search terms. A large volume of literature exists describing the design features, and experiments with the use, of thesauri in various types of information retrieval systems (see for example, Furnas et.al., 1987; Bates, 1986, 1998; Milstead, 1997, and Shiri et al., 2002).
