People proceed in their conversations through a series of dialogue acts to yield some specific communicative intention.

Abstract

People proceed in their conversations through a series of dialogue acts to yield some specific communicative intention. In this paper, we study the task of automatic labeling dialogues with the proper dialogue acts, relying on empirical methods and simply exploiting lexical semantics of the utterances. In particular, we present some experiments in both a supervised and an unsupervised framework on an English and an Italian corpus of dialogue transcriptions. In the experiments we consider the settings of dealing with or without additional information from the dialogue structure. The evaluation displays good results, regardless of the used language. We conclude the paper exploring the relation between the communicative goal of an utterance and its affective content.
