Following up on the OpenRefine suggestion, here's a blog post I wrote last year that describes using it to consolidate terms. http://acrl.ala.org/techconnect/?p=3276

Subject: [CODE4LIB] tool for finding close matches in vocabular list

Hi folks,

I'm looking for a tool that can look at a list of all of subject terms in a poorly-controlled index as possible candidates for term consolidation. Our student newspaper index has about 16,000 subject terms and they include a lot of meaningless typographical and nomenclatural difference, e.g.:

Irwin, Ken
Irwin, Kenneth
Irwin, Mr. Kenneth
Irwin, Kenneth R.

Basketball - Women
Basketball - Women's
Basketball-Women
Basketball-Women's

I would love to have some sort of pattern-matching tool that's smart about this sort of thing that could go through the list of terms (as a text list, database, xml file, or whatever structure it wants to ingest) and spit out some clusters of possible matches.

Does anyone know of a tool that's good for that sort of thing?

The index is just a bunch of MySQL tables - there is no real controlled-vocab system, though I've recently built some systems to suggest known SH's to reduce this sort of redundancy.

Any ideas?

Thanks!
Ken
