Passages and relevancy training are very important features of WDS to provide short and accurate answers to questions. But as relevancy training works only at document level, and the ranking of documents and passages are different, the value of these two important features can not be combined, what for me doesn't makes too much sense. If passages is the way to go to have short and accurate answers for a cognitive system, relevancy training should work at passage level.
Why is it useful?
