Joining contextual information to the intervention in natural language interfaces

We present a dialogue model which has as its main goal to place in context the utterance generated by the speaker. The dialogue model considers that an intervention generates one or more illocutionary acts which are handled as functions. These functions subcategorize to or are subcategorized by other functions in the dialogue. The model uses an exchange schema with the purpose of expressing the different functional subcategorizations. These schemas have properties close to the semantic forms of the verbs in a lexical-functional context
