Extended Faceted Taxonomies for Web Catalogs
Quote: “Which would be easier to remember: one thousand individual terms or three facets of ten terms each?…A faceted taxonomy is actually a set of taxonomies, called facets, each of which is a set of terms structured by a specialisation/generalisation relation. Using a faceted taxonomy, the indexing of objects is done by associating each object with a compound term, ie with a combination of terms coming from different facets.”
