a topic model matcher evaluating each of the patterns for the identified topic models against the digital information;
a visual display providing access to the digital information organized according to each of the topics in the subject area;
a query evaluator receiving a query comprising topic search terms and to match the topic search terms to the topics in the topic hierarchy; and
a characteristic word evaluator designating at least one of the chosen topics and the topic search terms as characteristic words, examining all of the evergreen indexes, and identifying those evergreen indexes in the visual display that comprise the characteristic words.
2. A system according to claim 1 , further comprising:
a textual content evaluator identifying textual content found in an article in the visual display, and matching the textual content to the topics in the topic hierarchy.
3. A system according to claim 1 , further comprising:
a user interface associating a ranking with each of the topics in the subject area of the at least one evergreen index as assigned by the online community, identifying the topics corresponding to the topic models identified and ranking the at least one evergreen index based upon the rankings associated with the topics identified, and biasing the topics provided in the visual display based on the ranking of their respective evergreen indexes.
4. A system according to claim 1 , wherein presentation of the at least one evergreen index based upon the closest matching of the topics to the user interest.
5. A system according to claim 4 , further comprising:
a user interface presenting the evergreen indexes visually separated in the display by associated augmented community.
6. A system according to claim 1 , wherein a guide is generated on demand comprising the article and the topics for each of the topic models identified.
7. A system according to claim 1 , wherein the digital information comprises one or more of printed documents, Web pages, and material written in a digital media.
8. A system according to claim 1 , further comprising:
a topic evaluator choosing the topics in the topic hierarchy based upon a topic of interest selected from at least one such topic hierarchy.
9. A system according to claim 8 , further comprising:
a scent indexer defining a fixed-size sliding window comprising textual content found in each of the articles comprised in the matching digital information, expanding the topic search terms, determining co-occurrences of the expanded topic search terms within the sliding window, applying a spreading activation to the topics in the topic hierarchy corresponding to the topic models that match the articles comprised in the matching digital information, and highlighting those topics in the visual display in the spreading activation.
10. A computer-implemented apparatus for providing orientation into digital information, comprising:
a memory; and
a processor operatively coupled to the memory and configured to execute computer executable program modules, including:
means for maintaining a plurality of evergreen indexes on a server for topically-limited subject areas, each of the subject areas comprising electronically-stored digital information and, for each of the evergreen indexes, comprising:
means for specifying a hierarchy of topics; and
means for pairing a topic model to each of the topics in the topic hierarchy, each of the topic models comprising a pattern evaluable against the digital information, wherein the pattern identifies such digital information matching the topic model's topic;
means for receiving a user interest in the digital information for the subject area of at least one of the evergreen indexes; and
means for evaluating each of the patterns for the identified topic models against the digital information;
means for providing access through a visual display to the digital information organized according to each of the topics in the subject area;
means for receiving a query comprising topic search terms and means for matching the topic search terms to the topics in the topic hierarchy;
means for designating at least one of the chosen topics and the topic search terms as characteristic words;
means for examining all of the evergreen indexes; and
means for identifying those evergreen indexes in the visual display that comprise the characteristic words.
11. A computer-implemented method for providing orientation into digital information, comprising:
maintaining a plurality of evergreen indexes on a server for topically-limited subject areas, each of the subject areas comprising electronically-stored digital information and, for each of the evergreen indexes, comprising:
specifying a hierarchy of topics; and
pairing a topic model to each of the topics in the topic hierarchy, each of the topic models comprising a pattern evaluable against the digital information, wherein the pattern identifies such digital information matching the topic model's topic;
receiving a user interest in the digital information for the subject area of at least one of the evergreen indexes;
evaluating each of the patterns for the identified topic models against the digital information;
providing access through a visual display to the digital information organized according to each of the topics in the subject area;
receiving a query comprising topic search terms and matching the topic search terms to the topics in the topic hierarchy;
designating at least one of the chosen topics and the topic search terms as characteristic words;
examining all of the evergreen indexes; and
identifying those evergreen indexes in the visual display that comprise the characteristic words.
12. A method according to claim 11 , further comprising:
identifying textual content found in an article in the visual display; and
matching the textual content to the topics in the topic hierarchy.
13. A method according to claim 11 , further comprising:
associating a ranking with each of the topics in the subject area of the at least one evergreen index as assigned by the online community;
identifying the topics corresponding to the topic models identified and ranking the at least one evergreen index based upon the rankings associated with the topics identified; and
biasing the topics provided in the visual display based on the ranking of their respective evergreen indexes.
14. A method according to claim 11 , further comprising:
biasing presentation of the at least one evergreen index based upon the closest matching of the topics to the user interest.
15. A method according to claim 14 , further comprising:
presenting the evergreen indexes visually separated in the display by associated augmented community.
