  • processing media content and a plurality of user generated profiles to extract keywords;

    generating a corpus of keywords using the extracted keywords;

    identifying which keywords from the corpus commonly co-occur in the user generated profiles and media content; and

    expanding a search query with additional search terms related to the search query, where the additional search terms are determined using one or more of the identified co-occurring keywords and by determining a correlation index between one or more terms of the search query and one or more keywords from the corpus, wherein the additional search terms have a correlation index above a threshold.
