چکیده

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 as well as speech acts using a maximum entropy model. The model can automatically acquire probabilistic discourse knowledge from an annotated dialogue corpus. Moreover, the model can analyze speech acts and discourse structures in one framework. In the experiment, the model showed better performance than other previous works. key words: speech act analysis, discourse structure analysis, maximum entropy model, statistical dialogue analysis model

Analysis System of Speech Acts and Discourse Structures Using Maximum Entropy Model

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 representati...

A Dialogue Analysis Model With Statistical Speech Act Processing For Dialogue Machine Translation

In some cases, to make a proper translation of an utterance in a dialogue, the system needs various information about context. In this paper, we propose a statistical dialogue analysis model based on speech acts for Korean-English dialogue machine translation. The model uses syntactic patterns and N-grams reflecting the hierarchical discourse structures of dialogues. The syntactic pattern inclu...

Discourse 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...

Modeling Lateral Communication in Holonic Multi Agent Systems

Agents, in a multi agent system, communicate with each other through the process of exchanging messages which is called dialogue. Multi agent organization is generally used to optimize agents’ communications. Holonic organization demonstrates a self-similar recursive and hierarchical structure in which each holon may include some other holons. In a holonic system, lateral communication occurs b...

Towards Learning Dialogue Structures from Speech Data and Domain Knowledge: Challenges to Conceptual Clustering using Multiple and Complex Knowledge Source

This paper introduces an engineering-oriented approach towards dialogue modelling. While dialogue models in existing dialogue systems usually are manually coded, or at least the data on which they are based is manually labeled, we investigate the possibility of learning dialogue models from a large set of example dialogues using real data in a spoken dialogue system. We assume the dialogue syst...
