Analysis System of Speech Acts and Discourse Structures Using Maximum Entropy Model
نویسندگان
چکیده
We propose a statistical dialogue analysis model to determine discourse structures as well as speech acts using maximum entropy model. The model can automatically acquire probabilistic discourse knowledge from a discourse tagged corpus to resolve ambiguities. We propose the idea of tagging discourse segment boundaries to represent the structural information of discourse. Using this representation we can effectively combine speech act analysis and discourse structure analysis in one framework.

An Integrated Dialogue Analysis Model for Determining Speech Acts and Discourse Structures
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 m...
متن کاملDiscourse Structures of Condolence Speech Act
Condolence is part of Austin’s expressive speech act and is related to Searle’s behabitives illocutionary act. Although a theoretically sound issue in pragmatics, condolence speech act has not been investigated as much as other speech acts in discourse-related studies. This paper aims at investigating interjections and intensifiers while performing condolence speech act among Persian and Englis...
متن کاملDialog Act Modeling for Conversational Speech
We describe an integrated approach for statistical modeling of discourse structure for natural conversational speech. Our model is based on 42 ~dialog acts’ (e.g., Statement, Question, Backchannel, Agreement, Disagreement, Apology), which were hand-labeled in 1155 conversations from the Switchboard corpus of spontaneous human-to-human telephone speech. We developed several models and algorithms...
متن کاملMaximum Entropy Model for Punctuat
In this paper we develop a maximum-entropy based method for annotating spontaneous conversational speech with punctuation. The goal of this task is to make automatic transcriptions more readable by humans, and to render them into a form that is useful for subsequent natural language processing and discourse analysis. Our basic approach is to view the insertion of punctuation as a form of taggin...
متن کاملAn Analysis of speeches of Hussein ibn Ali (AS) in the first step toward the incident of Karbala (Departing Medina to Mecca) based on John Searle’s Speech Acts
Linguistic theories can open new doors to historical analysis. This paper seeks to analyze the speeches of Hussein ibn Ali in the first step toward the incident of Karbala which was his departure from Medina to Mecca. The Speech Acts theory which roots in Discourse Analysis focuses on the role of language. It sees speech as an act that brings about actions in this world. Searle introduces only...
