Talk:Semantic network

From Wikipedia, the free encyclopedia

This article needs a short discussion of (and links to) the Semantic Web [[1]] and RDF [[2]] entries.

Also, DAML+OIL, Cyc and other existing ontologies.

[edit] semantic net = directed graph? really?

An Antonymy relationship is not directed. But if that is an important relationship of semantic nets, it anyways belongs to such a net. Thus, the semantic net cannot be directed. Correct?

Hence, I apply for the deletion of "directed" of "directed graph". --80.135.165.18 13:38, 25 February 2006 (UTC) (gneer, currently not logged in, since I don't have my pwd at hand)

[edit] Incorrect use of "Vertebrate" in image

"Vertebrate" in the image used as an illustration of a symantic network, base on the stated relation "has an", should be "Vertebra" because a vertebrate IS an animal with a spine--an animal with a spine is not something a mammal HAS--and a vertebra, which a mammal does have, is a bone of the spine. Alternatively, although it would reduce the number of types of relationships illustrated, the relation between Mammal and Vertebrate could be rewritten as "is a" rather than "has a" to indicate that a mammal is a vertebrate. In this latter case, the concept Animal could further be pointed to by the concept Vertebrate since the concept Vertebrate also has the semantic relation "is an" with respect to the concept Animal.--71.142.61.168 17:50, 17 June 2007 (UTC)

Thanks for pointing that out. I will try to correct the diagram changing Vertebrate->Vertebra (I think your second proposal would just look too cluttered - the diagram should just provide an illustration of semantic nets rather than a detailed structure on animals).--Konstable 12:08, 18 June 2007 (UTC)

[edit] Unclear

I don't understand this sentence: "Such networks involve fairly loose semantic associations that are nonetheless useful for human browsing." I think it is too judgmental about WordNet and it doesn't add information. Why "fairly loose"? —Preceding unsigned comment added by Sandman2007 (talk • contribs) 18:03, 27 November 2007 (UTC)
