Cognitive Interactive Search Based on Personalized User Model and Context

摘要

Mechanisms, in a Question and Answer (QA) system, are provided for performing a personalized context based search of a corpus of information. A question is received, by the QA system, from a first user via a source device. A first user profile associated with the first user, which specifies a personality trait of the first user, is retrieved. First candidate answers to the original question are generated based on a search of a corpus and second users having a similar personality trait to the personality trait of the first user are identified. Similar questions to that of the original question, which were previously submitted to the QA system by the one or more second users are identified. Second candidate answers based on the one or more similar questions are generated by the QA system. A final answer based on the first candidate answers and the second candidate answers is generated and output to the user via the source device.
