Main Page | See live article | Alphabetical index A Semantic feature is a notational method which can be used to to express the existence or non-existence of semantic properties by using plus and minus signs. Man is [+HUMAN], [+MALE], [+ADULT] Woman is [+HUMAN], [-MALE], [+ADULT] Boy is [+HUMAN], [+MALE], [-ADULT] Girl is [+HUMAN], [-MALE], [-ADULT] Intersecting semantic classes share the same features. Some features need not be specifically mentioned as their presence or absence is obvious from another feature. This is a redundancy rule. This article is from Wikipedia.
