Title:

Unsupervised and Constrained Dirichlet Process Mixture Models for Verb
Clustering

Speaker:

Andreas Vlachos
Computer Laboratory
Cambridge University

Abstract:

In this work we apply Dirichlet Process Mixture Models (DPMMs) to a
learning task in natural language processing (NLP): lexical-semantic
verb clustering. Furthermore, we propose a novel method of guiding the
DPMM towards a particular clustering solution using pairwise
constraints. The quantitative and qualitative evaluation performed
highlights the benefits of both standard and constrained DPMMs
compared to previously used approaches
