Unsupervised Language Model Adaptation Incorporating Named Entity Information

  title={Unsupervised Language Model Adaptation Incorporating Named Entity Information},
  author={Feifan Liu and Yang Liu},
Language model (LM) adaptation is important for both speech and language processing. It is often achieved by combining a generic LM with a topic-specific model that is more relevant to the target document. Unlike previous work on unsupervised LM adaptation, this paper investigates how effectively using named entity (NE) information, instead of considering all the words, helps LM adaptation. We evaluate two latent topic analysis approaches in this paper, namely, clustering and Latent Dirichlet… CONTINUE READING
