Abstract
The driving vision for our work is to provide intelligent, automated assistance to users in understanding the status of their email conversations. Our approach is to create tools that enable the detection and connection of speech acts across email messages. We thus require a mechanism for tagging email utterances with some indication of their dialogic function. However, existing dialog act taxonomies as used in computational linguistics tend to be too task- or application-specific for the wide range of acts we find represented
in email conversation. The Verbal Response Modes (VRM) taxonomy of
speech acts, widely applied for discourse analysis in linguistics and psychology, is distinguished from other speech act taxonomies
by its construction from crosscutting principles of classification, which ensure universal applicability across any domain of discourse. The taxonomy categorises on two dimensions, characterised as literal meaning and pragmatic meaning. In this paper, we describe a statistical classifier that automatically identifies the literal meaning category of utterances using the VRM classification. We achieve an accuracy of 60.8% using linguistic features
derived from VRM’s human annotation guidelines. Accuracy is improved to 79.8% using additional features.
