Context construction as subtask of dialogue processing - the VERBMOBIL case

In particular, it describes the Dialogue Memory which has been developed to represent contextual information acquired during dialogue processing. Information is stored both chronologically, i.e. in the order of appearance (in the Sequence Memory) and conceptually (in the Thematic Structure). We show how the Dialogue Memory is used to draw contextual inferences, some of which serve as basis for the detection of indirect speech acts. 1 Introduction This paper presents an approach for the representation of contextual information that was implemented as part of the face-to-face speech translation system verbmobil.
