Title

All the right descriptors : a test of the strategy of unlimited aliasing

Source

Journal of the American Society for Information Science. 44(1993) no.3, S.137-147

Abstract

The study tested the 'strategy of unlimited aliasing', an indexing method that places the alternative terms suggested by several indexers for the same information object into one index. The study aggregated the descriptors given to 21 bibliographic records from 3 databases: LISA (Library and information Science Abstracts); ISA (Information Science Abstracts); and ERIC. The subjects matched the records with descriptors in 7 different indexes that ranged from impoverished to enriched. No support for the strategy of unlimited aliasing was found
