In a vocabulary information system it is important to have a controlled vocabulary for information retrieval. However, when searching the data base of the National Technical Information Service (NTIS) for environmental research reports, one is faced with using search keywords from four thesauri as well as free language terms. These keyword sources are: The Department of Defense thesaurus, Energy Research and Development Administration thesaurus, National Aeronautic and Space Administration thesaurus, the thesaurus used by NTIS, and controlled free language terms. This microthesaurus integrated hierarchically the vocabulary of these five sources to allow easier retrieval for environmental terms. Generic relationships and thesaural origins are maintained for each term.
