[Sigia-l] crosswalks thesauri - does context matter?

[Eric Scheid]

When conducting a crosswalk from one thesauri to another, does context
matter?

For example: I have an arts journal publisher client, they are tagging their
journal indexes with terms from their private (specialist) thesauri, and
also tagging the articles with terms from LCSH. They want to do a cross walk
from LCSH to DDC, and have the corresponding DDC terms automatically
included when they export articles tagged with LCSH terms.

If another journal publisher wants to do the same thing, and assuming they
have an overlap in LCSH terms (eg. metal-work arts and glass-work arts both
use furnaces), would it be sensible for the second publisher to just assume
the cross walk results of the first publisher, or would their different
contexts result in different cross walks?
