11. A system comprising: a processor; and a non-transitory computer-readable medium having encoded thereon a sequence of instructions which, when loaded and executed by the processor, causes the processor to implement: a structure generation module configured to retrieve, from a memory, a global structure and a plurality of candidate answers therein; a computation module including: (i) a first computation unit configured to compute a first probability of a candidate answer based on a local structure of the candidate answer within the global structure; (ii) a second computation unit configured to compute a second probability of the candidate answer based on content of the candidate answer given content of a query; and (iii) a third computation unit configured to compute a third probability of the candidate answer based on context of the candidate answer given the content of the query; and a combination module configured to provide a combined probability for the candidate answer as a function of the first probability, second probability, and third probability.
