Unsupervised topic modelling for multi-party spoken discourse
2006
Proceedings of the 21st International Conference on Computational Linguistics and the 44th annual meeting of the ACL - ACL '06
Preserved Fulltext
We present a method for unsupervised topic modelling which adapts methods used in document classification (Blei et al., 2003; Griffiths and Steyvers, 2004) to unsegmented multi-party discourse transcripts ...
We show how Bayesian inference in this generative model can be used to simultaneously address the problems of topic segmentation and topic identification: automatically segmenting multi-party meetings ...
We thank Elizabeth Shriberg and Andreas Stolcke for providing automatic speech recognition data for the ICSI corpus and for their helpful advice; John Niekrasz and Alex Gruenstein for help with the NOMOS ...

In this paper, we describe a method for leader detection in multiparty spoken discourse that relies on unsupervised topic modeling to segment the discourse automatically. ...
Latent Dirichlet allocation is applied to sliding temporal windows of utterances, resulting in a topic model which captures the fluid transitions from topic to topic which occur in multi-party discourse ...
SUMMARY In this paper, we hypothesized that topics shifts occurring during multi-party spoken discourse could lend important clues towards leader detection. ...

This chapter discusses the task of topic segmentation: automatically dividing single long recordings or transcripts into shorter, topically coherent segments. ...
We then explain the most influential approaches -generative and discriminative, supervised and unsupervised -and discuss their application in particular domains. ...
While the distinction between two-party and multi-party dialogue can be very useful in some contexts, we intend the term dialogue to cover both here. ...
