Speech Act Modeling of Written Asynchronous Conversations with Task-Specific Embeddings and Conditional Structured Models
نویسندگان
چکیده
This paper addresses the problem of speech act recognition in written asynchronous conversations (e.g., fora, emails). We propose a class of conditional structured models defined over arbitrary graph structures to capture the conversational dependencies between sentences. Our models use sentence representations encoded by a long short term memory (LSTM) recurrent neural model. Empirical evaluation shows the effectiveness of our approach over existing ones: (i) LSTMs provide better task-specific representations, and (ii) the global joint model improves over local models.

متن کاملDialogue Act Recognition in Synchronous and Asynchronous Conversations
In this work, we study the effectiveness of state-of-the-art, sophisticated supervised learning algorithms for dialogue act modeling across a comprehensive set of different spoken and written conversations including: emails, forums, meetings, and phone conversations. To this aim, we compare the results of SVM-multiclass and two structured predictors namely SVMhmm and CRF algorithms. Extensive e...
متن کاملThe Impact of Deductive, Inductive, and L1-Based Consciousness-Raising Tasks on EFL Learners' Acquisition of the Request Speech Act
The necessity and importance of teaching pragmatics has come to light by many researchers (e.g. Rose & Kasper, 2001). Due to the consensus over the need to teach pragmatic competence, the main issue now centers on the question of how we should teach this competence in the most effective way. Consistent with this line of research, the present study aimed to investigate the effectiveness of deduc...
متن کاملThe Effect of Output-based Task Repetition on EFL Learners’ Speech Act Production
This study investigated the effects of different output-based task repetition conditions on EFL learners’ speech act production. Three intact classes of English-major students constituted three instructional groups: (1) the explicit task-repetition (ETR) group, (2) the implicit task-repetition (ITR) group, and (3) the no-input task repetition (NTR) group. All the three groups engaged in t...
متن کاملThe Effects of Collaborative Translation Task on the Apology Speech Act Production of Iranian EFL Learners
The present study aims to investigate the relative effectiveness of different types of pragmatic instruction including two collaborative translation tasks and two structured input tasks with and without explicit pragmatic instruction on the production of apologetic utterances by low-intermediate EFL learners. One hundred and fifty university students in four experimental groups and one control ...
