If a document is about mammals, it is about animals. sorry to jump in, but I don't think so: a document about mammals is not about animals, it is about a special kind of animals. If you're searching for information about the concept "animal", you're probably not interested with a document about platypus. When searching, it should be up to the user to decide whether she wants all documents about all kinds of animals, or just documents about the concept "animal". Semanlink for instance (which uses skos in a tagging system) give both results: http://www.semanlink.net/tag/animal.html http://www.semanlink.net/tag/animal.html?mode=1 Regards, fpsReceived on Friday, 6 June 2008 13:51:45 GMT
