A system includes a question processing circuit, an answer processing circuit, a mining circuit, and a question determination circuit. The question processing circuit is configured to receive a first question. The answer processing circuit is configured to generate a first answer set corresponding to the first question. The first answer set corresponds with one or more evidence passages. The mining circuit is configured to mine the evidence passages to identify a geospatial or temporal modifier. The question determination circuit is configured to generate a second question based on the first question and the geospatial or temporal modifier. The answer processing circuit is further configured to generate a second answer set corresponding to the second question and return a question answer set based on the second answer set to a user.
