System And Method For Providing Orientation Into Subject Areas Of Digital Information For Augmented Communities

A computer-implemented system for providing orientation into subject areas of digital information for augmented communities, comprising:

• a memory;
• a processor operatively couple to the memory and configured to execute computer executable program modules, comprising:
• an information collection module configured to obtain a plurality of topics for each subject area in a plurality of subject areas, each subject area being associated with an augmented community, each topic being hierarchically organized under a fine-grained topic category in a topic hierarchy;
• an information storage module configured to maintain a plurality of evergreen indexes, each evergreen index comprising a plurality of topic models that are each matched to one of the topics in the topic hierarchy associated with each augmented community;
• an interrelatedness module configured to determine interrelatedness of the plurality of evergreen indexes by identifying the topics found in the topic hierarchy for each evergreen index that are shared;
• a social network module configured to arrange a social network comprising neighbors made up of each augmented community associated with each of the plurality of evergreen indexes that are interrelated;
• an interest module configured to determine a user interest in digital information for a subject area;
• an evaluation module configured to evaluate each of the plurality of topic models for the evergreen indexes against the digital information, comprising;
• a best matching module configured to identify one of the evergreen indexes quantitatively best matched to the digital information;
• and
• a neighbor matching module configured to identify the other evergreen index associated with each augmented community that is a neighbor of the augmented community with the identified evergreen index;
• and
• an evergreen index access module configured to provide access to the digital information of the subject area via at least one of the identified best matched evergreen index and the identified other evergreen index.
