Answer Validation is a topic of significant in- terest within the Question Answering commu- nity. In this paper, we propose the use of language modeling methodologies for Answer Validation, using corpus-based methods that do not require the use of external sources. Specifi- cally, we propose a model for Answer Credibil- ity which quantifies the reliability of a source document that contains a candidate answer and the Question’s Context Model.
