This research studies the text genre of mes- sage board forums, which contain a mix- ture of expository sentences that present fac- tual information and conversational sentences that include communicative acts between the writer and readers. Our goal is to create sentence classifiers that can identify whether a sentence contains a speech act, and can recognize sentences containing four different speech act classes: Commissives, Directives, Expressives, and Representatives. We con- duct experiments using a wide variety of fea- tures, including lexical and syntactic features, speech act word lists from external resources, and domain-specific semantic class features. We evaluate our results on a collection of mes- sage board posts in the domain of veterinary medicine.
