Question answering systems (like watson) initially generate a lot of possible candidate answers in order to increase the recall. The candidate answers are, then, scored using various techniques to increase the precision. Many times the single document may contain the evidences for the candidate answer, but it may not be contiguous thus resulting into low score given to the answer. The proposal is to score a candidate answer using the projection of a document with respect to a given set of concepts (derived from question analysis and candidate answers).
