1. A method comprising:

  • tracking user behavior across multiple modalities for interacting with a device;

    storing representations of the user behavior in a log as descriptors, each descriptor associated with a modality, the descriptors comprising a first descriptor associated with a first modality and a second descriptor associated with a second modality, wherein the first modality and the second modality are distinct modalities;

    normalizing the descriptors, wherein the first descriptor and the second descriptor are normalized based on;

    (1) the first modality, (2) the second modality, (3) the device, and (4) a format associated with the device, to yield normalized descriptors;

    merging the normalized descriptors into a unified click stream;

    generating a behavioral model by analyzing the unified click stream; and

    upon receiving user input associated with modifying a presentation of search results associated with a search, dynamically modifying the presentation by using the behavioral model to generate the search results.
