Title: PC analysis of key words — And key key words
Abstract: Taking as its starting point the category text (as opposed to clause, collocation span, sentence etc.) this paper proposes and illustrates a method of identifying key words in text, and leads from this to the notion of key key words (words that are key in many texts). A key key word is shown to have associates: words that are key in the same texts as a given key key word. Finally, these associates can be grouped together in clumps, which themselves are revealing about text schemata and stereotype. The number of clumps in which any key key word participates relates not to ambiguity but to a diversity of perceived roles; the members of the clump describe and illuminate these stereotypical roles.
