In this paper, we propose a joint model for unsupervised Chinese word segmentation (CWS). Inspired by the " products of experts " idea, our joint model firstly combines two generative models, which are word-based hierarchical Dirichlet process model and character-based hidden Markov model, by simply multiplying their probabilities together. Gibbs sampling(More)

Unlike previous work, our research introduces a layer of hidden concepts and view senses as mixtures of concepts. We believe that concepts generalize the contexts, allowing(More)
