Cue-based dialogue act classification
Cue-Based Dialogue Act Classification Nick Webb Supervisors: Yorick Wilks & Mark Hepple In this thesis, we will address three research questions relating to the discovery and use of cue phrases for Dialogue Act classification. Cue phrases are single words, or combinations of words in phrases, that can serve as reliable indicators of some discourse function. In our case, we are looking to automa...
متن کاملDialogue Act Recognition using Cue Phrases
Dialogue acts play an important role in modelling discourse phenomena in several components of modern dialogue systems. Many different features have been so far proposed for dialogue act recognition. In this report, we take a cue-based model approach, and use N grams in utterances in dialogue as cue phrases. In our experiment with the switchboard corpus, we obtained 57.1% classification accurac...
متن کاملCue Phrase Selection In Instruction Dialogue Using Machine Learning
The purpose of this paper is to identify e ective factors for selecting discourse organization cue phrases in instruction dialogue that signal changes in discourse structure such as topic shifts and attentional state changes. By using a machine learning technique, a variety of features concerning discourse structure, task structure, and dialogue context are examined in terms of their e ectivene...
متن کاملDynamic Bayesian networks and variable length genetic algorithm for designing cue-based model for dialogue act recognition
The automatic recognition of dialogue act is a task of crucial importance for the processing of natural language dialogue at discourse level. It is also one of the most challenging problems as most often the dialogue act is not expressed directly in speaker’s utterance. In this paper, a new cue-based model for dialogue act recognition is presented. The model is, essentially, a dynamic Bayesian ...
متن کاملDialogue Act Recognition for Text-based Sinhala
This paper discusses the application of classical machine learning approaches to the task of Dialogue Act Recognition for text-based Sinhala. A study was carried out to identify a dialogue act tag set for Sinhala. A new corpus using Sinhala subtitles for English movies was created and was annotated with the selected dialogue acts. Evaluation of the dialogue act recognition system was performed ...
