Analyzing and Answering Questions

A computer-implemented method comprising:

• receiving, at a computer system, a question;
• identifying, by the computer system, one or more first semantic elements in the question;
• selecting, from one or more electronic documents, a plurality of candidate responses to the question based on comparison of the one or more first semantic elements to second semantic elements that have been identified in the plurality of candidate responses;
• determining completeness scores for the plurality of candidate responses, wherein each of the completeness scores indicates how completely a corresponding candidate response from the plurality of candidate responses answers the question;
• determining relevance scores for the plurality of candidate responses, wherein each of the relevance scores indicates how relevant a corresponding candidate response from the plurality of candidate responses is to the question;
• and
• providing, by the computer system, at least a portion of the plurality of candidate responses based, at least in part, on the completeness scores and the relevance scores.
