Abstract—We propose a new dialogue management model that incorporates contextual and linguistic features of utterances. Our model is based on the use of a systemic functional linguistic resource, the Semiotic Base, which enables the unified systematic treatment of contextual, semantic and lexicogrammatical features of language. The Semiotic Base is used to identify the situation type of a user's input text, to set up resources in accordance with the situation type, and to analyze and generate the text. The result of the analysis is represented with a set of linguistic features, which is used by the plan module to identify the stage in a dialogue, and to select the following moves of the system. In this paper, we explain how our dialogue management model with the Semiotic Base is applied to an intelligent secretary agent system that helps a user manipulating application software, and discuss the expected advantages of our approach.
