1. A computer-implemented method comprising:

  • identifying, by a computer, in one or more document corpora of a data source, a topic of interest based upon one or more concurring topics identified in the one or more document corpora;

    automatically extracting, by the computer, from a document corpus, data associated with a plurality of co-occurring topics based on the topic of interest;

    in response to automatically extracting the data associated with the plurality of co-occurring topics, extracting, by the computer, a plurality of topic identifiers from the plurality of co-occurring topics;

    generating, by the computer, a periodic topic model comprising a set of one or more term vectors by comparing topic significance among the plurality of topic identifiers;

    periodically creating, by the computer, new topic ID models using data content in the periodic topic model by identifying a similarity of topics, wherein the new topic ID models are stored in an in-memory database; and

    linking, by the computer, data in the in-memory database for automated discovery of new topics.
