Abstract: A computer-based method for generating intelligence from social media data, such as blog data, that is publicly available on the Internet. A server is provided that runs a tribe analysis tool, and the method includes accessing a set of the social media data with the tribe analysis tool. The social media data is associated with a plurality of network users or authors. The method continues with operating the tribe analysis tool to identify members of a tribe from the authors by processing the set of social media data to determine the authors having associated portions of the social media data that satisfies tribe membership criteria. Common interests for the identified members of the tribe are determined by processing the social media data associated with the tribe authors. A report is generated for the tribe that includes information related to the set of common interests and additional generated tribe-based intelligence.
