A major concern in genre analysis is to answer the question how language varies when we use it fordifferent purposes in different situations. This paper begins with a brief review of Hasans theoreticalframework for generic structuring of texts (1984), which is based on Hallidays semantically drivenmodel of language description (1989). It then considers some options in the network representation onthe semantic level and exemplifies the notion of semantic networks, as postulated by Hasan and Cloran(1994), with an analysis of blogs.
