    Abstract
    Despite early claims to the contemporary, thesauri continue to find use as access tools for information in the full-text environment. Their mode of use is changing, but this change actually represents an expansion rather than a contrdiction of their utility. Thesauri and similar vocabulary tools can complement full-text access by aiding users in focusing their searches, by supplementing the linguistic analysis of the text search engine, and even by serving as one of the tools used by the linguistic engine for its analysis. While human indexing contunues to be used for many databases, the trend is to increase the use of machine aids for this purpose. All machine-aided indexing (MAI) systems rely on thesauri as the basis for term selection. In the 21st century, the balance of effort between human and machine will change at both input and output, but thesauri will continue to play an important role for the foreseeable future

    Abstract
    Report on a subject analysis review undertaken to aid managers of databases in determining if new and little-known capabilities would improve the cost-effectiveness of subject analysis operations. Operational machine-aided and automatic indexing systems were found to form a continuum. Commercial automatic indexing packages were also reviewed. The primary obstacle to development of automatic indexing is the lack of machine understanding of natural language. Recommendations for action include: increasing the power of the indexer interface, studying indexing policies, enrichment of thesauri, and considering the development of machine-aided indexing

    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
