    Abstract
    This study is an attempt to assess the potential for automatic vocabulary switching from a thesaurus to LCSH. Terms from the 'Laborline Thesaurus' were manually mapped to LCSH, with the degree of match indicated by a code from 1 to 19, representing the nature of the match from exact match to no match. Am INMAGIC database for the amp was created in order to permit analysis of the aptterns of matches to see whether there were regularities that could be exploited to improve the performance of switching interfaces. Searches of the database by match codes reveal ranges of 21,98% for no matches to 0,06% for translation matches, with 16,3% for exact matches. It is estimated that a maximum of 61%, but a more realistic figure of 41,5%, of the terms coulc be successfully switched automatically using currently proposed or available strategies. As long as LCSH is used for subject descriptions in online catalogs, it would appear that intelligent interfaces for vocabulary switching can only be partially successful, and it is suggested that manual mapping, while labor-intensive, is a feasible alternative

    Abstract
    In this era of the Internet and distributed, multimedia computing, new and emerging classes of information systems applications have swept into the lives of office workers and people in general. From digital libraries, multimedia systems, geographic information systems, and collaborative computing to electronic commerce, virtual reality, and electronic video arts and games, these applications have created tremendous opportunities for information and computer science researchers and practitioners. As applications become more pervasive, pressing, and diverse, several well-known information retrieval (IR) problems have become even more urgent. Information overload, a result of the ease of information creation and transmission via the Internet and WWW, has become more troublesome (e.g., even stockbrokers and elementary school students, heavily exposed to various WWW search engines, are versed in such IR terminology as recall and precision). Significant variations in database formats and structures, the richness of information media (text, audio, and video), and an abundance of multilingual information content also have created severe information interoperability problems -- structural interoperability, media interoperability, and multilingual interoperability.
