1. A computer-implemented method for returning temporally aware results for a query, comprising:

  • identifying a first set of results for a query, the first set of results non-temporally based;

    classifying whether the query is temporally based by inputting one or more features of the query into a trained classifier to assign a classification to the query;

    if the query is classified as temporally based, determining an alternate set of results for the query different than the first set of results; and

    updating the classification based upon user interaction with the alternate set of results, comprising;

    representing the one or more features of the query as a vector of coordinates in feature space, the vector of coordinates assigned a temporally based label if the query is classified as temporally based; and

    if the user interaction with the alternate set of results indicates the query is non-temporally based and the vector of coordinates is assigned the temporally based label, then;

    modifying the temporally based label assigned to the vector of coordinates to a non-temporally based label; and

    updating a margin separating a temporally-based query region and a non-temporally based query region in the feature space, at least some of at least one of the identifying, the classifying, the determining, and the updating the classification implemented at least in part via a processor.
