Energy microthesaurus: a hierarchical listing of energy indexing terms used in the NTIS data base
In a computerized 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 'energy' research reports, one is faced with using search keywords from four thesauri as well as free language terms. These keyword sources are the following: The Department of Defense thesaurus, the Energy Research and Development Administration thesaurus, the National Aeronautic and Space Administration thesaurus, the thesaurus used by NTIS, and controlled free language terms used by NTIS to describe concepts not covered in any of the above thesauri. This microthesaurus integrates hierarchically the vocabulary of these five sources so as to allow easier retrieval of the NTIS data base and to act as an indexing vocabulary for energy terms. Generic relationships and thesaural origins are maintained for each term. Over 600 terms were chosen for their usage in expressing energy concepts including those for fuels, fuel sources, energy demand, conservation, electric power generation, heating, energy conversion, and fuel processing.
