NOPQRSTUVWXYZ Introduction

The Rotated Term Display is made available as a ready–reference tool to provide better access to the terms in NASA Thesaurus, Volume 1 – Hierarchical Listing With Definitions. The Rotated Term Display is essentially a key-word-in-context (KWIC) index that provides access to every word in postable terms and nonpostable USE references. Once the desired postable term has been located, the complete hierarchical information for that term should be consulted in the Hierarchical Listing.

USE References

Full cross references from nonpostable to postable terms are provided as part of the rotated display; for example, the USE reference leading to the term launch vehicles below:

carrierĄrockets use launch vehicles

Stopwords

Certain words having questionable access value (such as and, of, in, etc.) are not included in the rotated term sort. For the same reason, purely numeric strings and non–alphanumeric characters are not included in the sort.

Glosses

A gloss is a word or words enclosed in parentheses at the end of a term. Glosses serve to disam- biguate homographs (i.e., terms that are spelled alike but have dif ferent meanings), as in outliers (landforms) and outliers (statistics). In addition, glosses may indicate the general scope of a term, for example activity cycles (biology).

In the Rotated Term Display, parentheses are ignored in the basic sort so that gloss words are displayed with similar words, as in the following example:

geometrical theory of diffraction analytic geometry angles (geometry) Bose geometry chords (geometry) variable geometry structures

Uppercase and Lowercase Authority

As with Volume 1, the Rotated Term Display provides upper/lowercase authority for all of its terms and cross references.

16. Abstract The NASA Thesaurus contains the authorized subject terms by which the documents in the NASA Aeronautics and Space Database are indexed and retrieved. The scope of this controlled vocabulary includes, not only aerospace engineering, but all supporting areas of engineering and physics, the natural space sciences (astronomy, astrophysics, planetary science), Earth sciences, and to some extent, the biological sciences. It contains over 18,300 subject terms and approximately 4,500 USE references. Volume 2 – Rotated Term Display, is made available as a ready-reference tool to provide better access to the terms in the Hierarchical Listing With Definitions (Volume 1). The Rotated Term Display is essentially a key-word-in-context (KWIC) index that provides access to every word in postable terms and nonpostable USE references. It provides approximately 52,000 additional ‘access points’ to the thesaurus terminology.
