1. A method for scalable user intent mining, comprising:

  • detecting named entities from a plurality of query logs in a public query log dataset;

    based on the detected named entities, generating corresponding features of the plurality of query logs;

    applying a multimodal restricted boltzmann machine (RBM) on the corresponding features of the plurality of query logs to train a public multimodal RBM;

    generating a plurality of public query representations;

    receiving a search query from a user;

    determining whether there are a plurality of history queries of the user;

    when there is no history query of the user, predicting user intent using the public multimodal RBM; and

    when there are the plurality of history queries of the user, applying the public multimodal RBM on the plurality of history queries of the user to train a personalized multimodal RBM, and predicting the user intent using the personalized multimodal RBM.
