Abstract: Discovering topics of interest from the content received from multiple sources. Content from multiple sources is aggregated and stored in a database along with the content's metadata. Phrases are extracted from the content and scored based on at least a time window for each phrase. The high ranking phrases are presented to a user via a user interface. When a user selects a particular phrase, content corresponding to the selected phrase is presented to the user. The content may include a list of ranked documents or a specific document. The phrases presented to the user can also be topic specific.
