Salton, Gerard; Buckley, Chris
It is customary to use single terms (words) or terms in context (phrases) as indexing units for the representation of natural-language text content.

This note presents an evaluation of the expected usefulness of automatic term phrase generation systems involving syntactic processing compared with methods based only on the statistical co-occurance characteristics between individual text words.
