  • Bayesian Topic Models have been used in different fields of natural language processing to help extract information from unstructured text. Specifically previous research on topic model based retrieval methods has shown significant performance improvements. This paper deals with more complex models of information extraction, namely Question/Answering (QA) models. For any given question posed in natural language, QA systems are designed to extract possible answer as a semantic group or a pre… CONTINUE READING
