    Abstract
    Specifications are presented for software designed to support manual development and maintenance of information retrieval thesauri. The specifications are intended to support both evaluation of existing packages for acquisition and design of custom software. Specialized requirements of thesaurus support are emphasized over more general database management requirements. Requirements for integration with larger systems and for the user interface are summarized. Relationships specified by the ANSI standard should be supported, and the relationships should be validated to avoid introduction of conflicting relationships. Flexibility in availability of note and date fields is important, and where required, term classifications should be available. Maintenance procedures should include provision for feedback on the impact of changes, as well as appropriate levels of approval for changes. A wide variety of online displays and printed reports are required, including but not limited to alphabetical, hierarchical, and rotated. In addition, it is desirable to be absle to search the thesaurus database with such capabilities as Boolean logic and proximity operators

    Abstract
    Relationships between the terms in thesauri and Indexes are the subject of national and international standards. The standards for thesauri enumerate and provide criteria for three basic types of relationship: equivalence, hierarchical, and associative. Standards and guidelines for indexes draw an the thesaurus standards to provide less detailed guidance for showing relationships between the terms used in an Index. The international standard for multilingual thesauri adds recommendations for assuring equal treatment of the languages of a thesaurus. The present standards were developed when lookup and search were essentially manual, and the value of the kinds of relationships has never been determined. It is not clear whether users understand or can use the distinctions between kinds of relationships. On the other hand, sophisticated text analysis systems may be able both to assist with development of more powerful term relationship schemes and to use the relationships to improve retrieval.
