Abstract

A system and method for indexing content. The system includes a crawler, a crawl database, an indexer, a classification application, and an indexed data server. The crawler is configured to crawl the internet for content objects. The crawl database is coupled to the crawler and configured to cache the content objects. The indexer is coupled to the crawl database and configured to perform feature extraction on the content objects and cluster the content objects by generating an object vector. The classification application is coupled to the indexer and configured to cluster the object vectors and generate a summary vector. The indexed data server is coupled to the indexer and configured to communicate the content objects with a client.

Claims

1. A system for indexing content, the system comprising:

a crawler to crawl the internet for content objects;

a crawl database coupled to the crawler, the crawl database to cache the content objects;

an indexer coupled to the crawl database, the indexer to perform feature extraction on the content objects and cluster the content objects by generating an object vector;

a classification application coupled to the indexer, the classification application to cluster the object vectors and generate a summary vector; and

an indexed data server coupled to the indexer, the indexed data server to communicate the content objects with a client.

2. The system of claim 1, wherein the object vector comprises a vector of numbers representative of a frequency of a superset of features potentially found in the content object.

3. The system of claim 1, wherein the indexer pre-processes the content object with a form of scaling selected from the group consisting of Term Frequency Scaling, Inverse Document Frequency scaling, and Term Frequency Inverse Document Frequency scaling.

4. The system of claim 1, wherein the summary vector comprises a weighted sum of a plurality of object vectors.

5. The system of claim 1, wherein the indexer clusters object data into static modules for distribution to clients.

6. The system of claim 1, further comprising a template of an interest tagged with a pre-defined set of positive and negative examples.

7. The system of claim 1, further comprising an accordion interface application coupled to the client, the accordion interface application to selectively open and close portions of a user interface mechanism in response to a set of restrictions.

8. The system of claim 1, further comprising a user relevance application coupled to the client, the user relevance application to infer a user preference based upon at least one browsing characteristic selected from the group consisting of gaps in user activity, length of time spent on a particular page, interaction with a page, content objects clicked on a particular page, and how a user navigates away from a particular page.

9. The system of claim 1, further comprising a negative examples application coupled to the client, the negative examples application to improve a user preference by generating negative examples when a user has not identified any content objects as negative.

10. The system of claim 1, further comprising a smart scrolling application coupled to the client, the smart scrolling application to scroll lists in an infinite tape loop fashion and having buttons to enable play, stop, fast forward, and rewind functionality.

11. The system of claim 1, further comprising:

a web application server coupled to the internet, the web application server to execute a plurality of functions other than user interface functions at a client; and

a client database coupled to the web application server, the client database to store data related to the plurality of functions of the web application server.

12. A computer program product comprising a computer useable storage medium to store a computer readable program that, when executed on a computer, causes the computer to perform operations for indexing content, the operations comprising:

crawl the internet for content objects;

cache the content objects;

perform feature extraction on the content objects and cluster the content objects by generating an object vector;

cluster the object vectors and generate a summary vector; and

communicate the content objects with a client.

13. The computer program product of claim 12, wherein the computer readable program, when executed on the computer, causes the computer to perform an operation to pre-process the content object with a form of scaling selected from the group consisting of Term Frequency Scaling, Inverse Document Frequency scaling, and Term Frequency Inverse Document Frequency scaling.

14. The computer program product of claim 12, wherein the computer readable program, when executed on the computer, causes the computer to perform an operation to sum a plurality of object vectors.

15. The computer program product of claim 12, wherein the computer readable program, when executed on the computer, causes the computer to cluster object data into static modules for distribution to clients.

16. The computer program product of claim 12, wherein the computer readable program, when executed on the computer, causes the computer to selectively open and close portions of a user interface mechanism in response to a set of restrictions.

17. The computer program product of claim 12, wherein the computer readable program, when executed on the computer, causes the computer to infer a user preference based upon at least one browsing characteristic selected from the group consisting of gaps in user activity, length of time spent on a particular page, interaction with a page, content objects clicked on a particular page, and how a user navigates away from a particular page.

18. The computer program product of claim 12, wherein the computer readable program, when executed on the computer, causes the computer to improve a user preference by generating negative examples when a user has not identified any content objects as negative.

19. The computer program product of claim 12, wherein the computer readable program, when executed on the computer, causes the computer to scroll lists in an infinite tape loop fashion and having buttons to enable play, stop, fast forward, and rewind functionality.

20. A method for indexing content, the method comprising:

crawling the internet for content objects;

caching the content objects;

performing feature extraction on the content objects and cluster the content objects by generating an object vector;

clustering the object vectors and generate a summary vector; and

communicating the content objects with a client.

21. The method of claim 20, further comprising pre-processing the content object with a form of scaling selected from the group consisting of Term Frequency Scaling, Inverse Document Frequency scaling, and Term Frequency Inverse Document Frequency scaling.

22. The method of claim 20, further comprising selectively opening and closing portions of a user interface mechanism in response to a set of restrictions.

23. The method of claim 20, further comprising inferring a user preference based upon at least one browsing characteristic selected from the group consisting of gaps in user activity, length of time spent on a particular page, interaction with a page, content objects clicked on a particular page, and how a user navigates away from a particular page.

24. The method of claim 20, further comprising improving a user preference by generating negative examples when a user has not identified any content objects as negative.

25. The method of claim 20, further comprising scrolling lists in an infinite tape loop fashion and having buttons to enable play, stop, fast forward, and rewind functionality.
