- 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
