An Integrated Dialogue Analysis Model for Determining Speech Acts and Discourse Structures

Abstract: Won Seug CHOI †a) , Harksoo KIM †b) , and Jungyun SEO † †c) , Members SUMMARY Analysis of speech acts and discourse structures is essential to a dialogue understanding system because speech acts and discourse structures are closely tied with the speaker's intention. However, it has been difficult to infer a speech act and a discourse structure from a surface utterance because they highly depend on the context of the utterance. We propose a statistical dialogue analysis model to determine discourse structures a… Show more

“…Lee [3] designed a speech-act classification method using the hidden Markov model (HMM) to estimate speech-act probabilities and this method was improved upon by using smoothed class probabilities from a decision tree. Choi [4] proposed a maximum entropy model (MEM) to determine the speech-act of current utterances using previous utterances as contextual information. Song [5] recommended a support vector machine (SVM) model to preferentially analyze classes with lower distribution when training among a set of classes.…”

“…Recently, statistical speech act classification using a tagged dialogue corpus has be en proposed in order to solve such problems (Kim et al, 2004;Lee and Seo, 2002;Choi et al, 2005). Most previous works on speech act classification have used two feature types: sentential features and contextual features.…”

“…The second component is a mandatory element of the Interchange Format representation, and sometimes an utterance may be assigned a speech act with no concepts or arguments (e.g. utterance (2) in Table 1). The third component, a concept sequence, is a set of domain-dependent concepts and may contain zero or more concepts.…”
