1. A method for responding to a query, the method comprising: performing the following with a processor: receiving an original query for information related to an action affecting a public population; extracting a first semantic query and a second semantic query from the original query, the first semantic query comprising a quantitative action term; transforming, based upon semantic analysis of the quantitative action term, the first semantic query into a numeric model query; determining semantic response data for the second semantic query based upon semantic analysis of unstructured data sources that comprise unstructured data pertaining to behaviors of the public population to determine response information for the original query; determining numeric response data for the numeric model query based upon at least one mathematical model incorporating numeric data associated with the public population to determine response information for the original query; and integrating the semantic response data and the numeric response data into an answer for the original query.
