Indexing problems and some of their solutions

American Documentation, 1966, vol. 17, issue 1, 17-25

Abstract: This paper concerns problems of redundancy and inaccuracy in the indexing of technical information, illustrated by the coordinate indexing scheme employed in the NASA Information System. A proposal is made for the elimination of “panacea” or “catch‐all” terms, and a rule for uniform grammatical negation is given. The effects of synonyms, antonyms, and negations on the overall efficiency of the information system are illustrated. Merits are discussed and rules are given for indexing under acronyms whenever possible. Finally, the concept of a “pictorial thesaurus” is proposed to exhibit hierarchy and connectivity of terms as an aid to indexing and retrieving of information.
