scope:

Utterances in interactive discourse, such as spoken dialogue, have one or more communicative functions that characterize the type of communicative action which the participants are performing; these functions carry an essential part of the meaning of dialogue utterances. An adequate characterization of this aspect of meaning requires a coherent system of well-defined communicative functions. This standard provides empirically as well as theoretically well-motivated concepts for defining communicative functions, for identifying dimensions of interaction that dialogue acts may address, and for functional dialogue segmentation. The standard specifies data categories for a set of core communicative functions for multidimensional dialogue act annotation, starting from proposals made jointly by the LIRICS project and the TC 37/SC 4 ad-hoc Thematic Domain Group (TDG) 3 on Semantic Content.
