A question relating to an individual is received and context from the question is extracted. Subject matter criteria can be identified from the context of the question. A database containing history data that includes recorded positional data for physical objects relative to the location of the individual at the time of recording can be accessed and relevant physical objects from the history data can be identified based upon the subject matter criteria. A set of answers can be generated for the question from a corpus of data and ranked based upon the identified physical objects and physical distance between the individual and the relevant physical objects.
