SYSTEM AND METHOD FOR A PURPOSEFUL SHARING ENVIRONMENT

1 . An information sharing system comprising:

a content storage system configured to store user content in a database, the content storage system comprising:

a user interface;

a search engine configured to retrieve content from the database based upon a query; and

a categorization engine configured to automatically categorize the user content into one or more partitions based on a weighted term vector;

a sharing system in communication with the content storage system, the sharing system configured to partition the user content into one or more partitions so that the one or more partitions may be shared with another user of the purposeful sharing system; and

a recommendation system in communication with the sharing system and the content storage system, the recommendation system configured to:

organize the user content into one or more cluster lists;

compute a measure of strength of a piece of content using a clustering algorithm across the one or more cluster lists;

compute a similarity score between one or more cluster lists by summing the reciprocal of the difference between the weights of matching clusters;

recommend the piece of content based on the similarity score.

2 . The system of claim 1 , wherein the content storage system is further configured to convert the user content to a format that enables non-destructive alteration to the user content.

3 . The system of claim 1 , wherein the content storage system is accessible via a web browser.

4 . The system of claim 1 , wherein the user interface is configured to present the user content as one or more categories.

5 . The system of claim 1 , wherein the user interface allows a user to apply a tag to at least a portion of the user content.

6 . The system of claim 1 , wherein the user content is categorized using the MoreLikeThis class in Lucene.

7 . The system of claim 1 , wherein categorization is based on a minimum threshold before being categorized.

8 . The system of claim 1 , wherein the categorization engine categorize the user content into a sub-category.

9 . The system of claim 1 , wherein the sharing system is permission based.

10 . The system of claim 1 , wherein a partition is only shared with a subset of the users of the purposeful sharing system.

11 . The system of claim 1 , wherein the similarity score incorporates the date the piece of content was added to the content storage system.

12 . The system of claim 1 , wherein the similarity score incorporates the date the user last viewed the piece of content.

13 . The system of claim 1 , wherein the similarity score incorporates negative information into the computation.

14 . The system of claim 13 , wherein the negative information is a reciprocal of non-matching clusters and is subtracted from the similarity score.

15 . The system of claim 1 , wherein the recommendation system is further configured to insert the piece of content into a particular user's content storage.

16 . The system of claim 1 , wherein the recommended content is a blog.

17 . A method for sharing information among a plurality of users comprising the steps of:

storing a user content in a database;

organizing the user content into discrete partitions;

sharing the partitions;

indexing the user content based on a weighted term vector;

organizing the user content into one or more cluster lists;

computing a measure of strength of a piece of content using a clustering algorithm across the one or more cluster lists;

computing a similarity score between one or more cluster lists by summing the reciprocal of the difference between the weights of matching clusters;

recommending the piece of content based on the similarity score.

18 . The method of claim 17 , further comprising the steps of: uploading the user content into the content storage system and converting the content into a format that enables non-destructive alteration to the user content.

19 . The method of claim 17 , presenting through a user interface the user content as one or more categories.

20 . The method of claim 17 , further comprising the step of tagging to at least a portion of the user content.

21 . The method of claim 17 , further comprising the step of categorizing the user content using the MoreLikeThis class in Lucene.

22 . The method of claim 17 , wherein categorization is based on a minimum threshold before being categorized.

23 . The method of claim 17 , further comprising the step of categorizing the user content into one or more sub-categories.

24 . The method of claim 17 , wherein sharing the content is permission based.

25 . The method of claim 17 , wherein further comprising the step of sharing a partition with a subset of the users of the purposeful sharing system.

26 . The method of claim 17 , further comprising the step of incorporating the date the piece of content was added to the content storage system into the similarity score.

27 . The method of claim 17 , further comprising the step of incorporating the date the user last viewed the piece of content into the similarity score.

28 . The method of claim 17 , further comprising the step of incorporating negative information into the similarity score.

29 . The method of claim 28 , wherein the negative information is a reciprocal of non-matching clusters and is subtracted from the similarity score.

30 . The method of claim 17 , further comprising the step of automatically inserting the recommended piece of content into a particular user's content storage.
