Abstract. Categorization dynamics as the clustering of words in word relation is studied by a constructive approach which is suited to inquire evolutionary linguistics with dynamical view on language. Word meaning is represented by relationship among words. Tthe relationship should be derived from usage of language. Being founded on this usage­based view, we define an algorithm to evaluate word relationship. Using the algorithm, cluster structure and its dynamics of words are shown in a model with communicating artificial agents. The relevance of clustering with linguistic categorization is discussed.
1 Dynamical View on Language There are two ways of viewing language: structurally and dynamically. The structural view is a static one in which language structure, for example, syn­ tax, dictionaries, or pragmatic rules, o#ers idealized approaches to language. The alternative view is dynamic. It concentrates on the actual use of language rather than abstract notions of how language ought to be. It is possible to better understand the value of the second approach by thinking of metaphor. Metaphor­ icalexpressions are creative and dynamic precisely because they can ``bend'' or ``break'' the rules of conventionally structured language. By producing or un­ derstanding metaphorical expressions, especially creative or unique metaphors, our internal models should change. We can not say valid or not valid for such creative expressions, since the expressions are so novel that it is not valid for a conventional language structure. We should consider whether the expressions are to be accepted or not. If we accept them, our internal structure changes and language structure might also come to be modified. In the dynamical view, the whole system of ...
