Key Word
a meaningful word in a text; used in coordinate indexing of the text. Each key word, like a descriptor, designates a class into which all texts with this word as a component of the basic meaning and content may fit. Unlike descriptors, key words are lexical units of a natural language: the same key word may have many meanings, and many key words may have the same meaning. In information retrieval a list of key words is used as a retrieval mark of a document or a retrieval requirement. Want to thank TFD for its existence?
