Relating multiple ontologies? "TBOX", "ABOX", multiple files, etc.
I have a task to "map" a few related class-hierarchies to each other. Essentially, we have a few similar database-models, and need to "harmonize" them. The emphasis is on the taxonomy aspects (TBOX: classes/entities).
Say, for example, I had 3 similar data-models describing the information used within a major organization. All 3 try to cover the entire organization, but they use different terms, and modeled the organization *quite* differently. Hence the problem.
In general, does anyone have any tips re:
* Doing the "mapping" between the 3 data-models at the TBOX (class/entity) or ABOX (property) level?
* Having everything in a single file, or having multiple files (ontologies)?
