Transitivity, categories and semantic links

There is a problem with transitivity: if article A belongs to category B and category B is included in category C, this should (could) mean that A is a C, or that A has a close relationship with C. The problem is that we lose meaning when we go deeper in the category tree: for example, we may have Category Law>Category Judges>Category makers of judge's wigs>Category Smith (a maker of wigs)>Category Smith's shop. Smith is not a judge, and his shop has little to do with law. So categories don't give us a "is a" relation nor transitive relations or transitive sets. Apokrif 14:29, 11 August 2006 (UTC)
