Latent Maximum Entropy Approach for Semantic N-Gram Language Modeling

Full Text: latent-maximum-entropy-approach.pdf PDF

In this paper, we describe a uni ed prob- abilistic framework for statistical language modeling|the latent maximum entropy principle|which can e ectively incorporate various aspects of natural language, such as local word interaction, syntactic structure and semantic document information. Unlike previous work on maximum entropy methods for language modeling, which only allow ex- plicit features to be modeled, our framework also allows relationships over hidden features to be captured, resulting in a more expres- sive language model. We describe eÆcient algorithms for marginalization, inference and normalization in our extended models. We then present promising experimental results for our approach on the Wall Street Journal corpus.
