Corpus Management Based on Question Affinity

摘要

Mechanisms are provided for managing a corpus of content. A question is processed by a Question Answering (QA) system to generate an answer to the question and a supporting evidence passage. A corpus value metric is calculated for the supporting evidence passage based on a determined number of times the supporting evidence passage is used to generate a high ranking answer to questions submitted to the QA system. A first corpus management operation is performed on the supporting evidence passage in response to determining that the corpus value metric meets or exceeds a first threshold, the first corpus management operation increasing a relative importance of the supporting evidence passage within the corpus. A second corpus management operation on the supporting evidence passage is performed in response to determining that the corpus value metric meets or falls below a second threshold, the second corpus management operation decreasing the passage's relative importance.
