Sharing content based on extracted topics
Examples of techniques for sharing content based on topics are described herein. A method includes extracting a content topic from a piece of content. The method includes extracting a user topic based on a user activity. The method also includes matching the content topic with the user topic and generating a user score based on a detected number activities a user performs that include a matched user topic. The method further includes generating a sorted list of users with matched user topics, the list to be sorted by the user score.
1. A computer-implemented method of distributing digital content, comprising:
extracting a plurality of content topics from a piece of digital content created by a first user;
identifying, for each of a plurality of users in a social network including the first user, user topics based on user activities for each respective one of the plurality of users;
generating a user score, for each of the plurality of users, based upon:
one of the user topics matching one of the plurality of content topics,
a type of user activity associated with the one of the user topics, and
a number of user activities associated with the one of the user topics;
generating a social score for a particular user of the plurality of users from a social graph that includes the first user and the plurality of users;
modifying the user score, for each of the plurality of users, with the social score respectively associated with each user to generate a modified user score;
sorting the plurality of users using the modified users scores for the plurality of users; and
sending the digital content to particular ones of the plurality of users based upon the sorting.
2. The method of claim 1 , wherein
the sorting and the sending is performed automatically without user intervention.
3. The method of claim 1 , wherein
the digital content is sent to the particular ones of the plurality of users based upon the particular ones of the plurality of users having user scores that exceed a threshold user score.
4. The method of claim 1 , wherein
the plurality of content topics and the user topics are normalized.
5. The method of claim 1 , wherein
the sorting creates a sorted list, and
the sorted list expires after a predetermined amount of time.
6. The method of claim 1 , wherein
the user activities include at least one of a status update, a wiki edit, and a browsing activity.
7. A computer-hardware system configured to distribute digital content, comprising:
a hardware processor configured to initiate the following executable operations:
extracting a plurality of content topics from a piece of digital content created by a first user;
identifying, for each of a plurality of users in a social network including the first user, user topics based on user activities for each respective one of the plurality of users;
generating a user score, for each of the plurality of users, based upon:
one of the user topics matching one of the plurality of content topics,
a type of user activity associated with the one of the user topics, and
a number of user activities associated with the one of the user topics;
generating a social score for a particular user of the plurality of users from a social graph that includes the first user and the plurality of users;
modifying the user score, for each of the plurality of users, with the social score respectively associated with each user to generate a modified user score;
sorting the plurality of users using the modified users scores for the plurality of users; and
sending the digital content to particular ones of the plurality of users based upon the sorting.
8. The system of claim 7 , wherein
the sorting and the sending is performed automatically without user intervention.
9. The system of claim 7 , wherein
the digital content is sent to the particular ones of the plurality of users based upon the particular ones of the plurality of users having user scores that exceed a threshold user score.
10. The system of claim 7 , wherein
the plurality of content topics and the user topics are normalized.
11. The system of claim 7 , wherein
the sorting creates a sorted list, and
the sorted list expires after a predetermined amount of time.
12. The system of claim 7 , wherein
the user activities include at least one of a status update, a wiki edit, and a browsing activity.
13. A computer program product, comprising:
a hardware storage device having stored therein program code,
the program code, which when executed by a computer hardware system, causes the computer hardware system to perform:
extracting a plurality of content topics from a piece of digital content created by a first user;
identifying, for each of a plurality of users in a social network including the first user, user topics based on user activities for each respective one of the plurality of users;
generating a user score, for each of the plurality of users, based upon:
one of the user topics matching one of the plurality of content topics,
a type of user activity associated with the one of the user topics, and
a number of user activities associated with the one of the user topics;
generating a social score for a particular user of the plurality of users from a social graph that includes the first user and the plurality of users;
modifying the user score, for each of the plurality of users, with the social score respectively associated with each user to generate a modified user score;
sorting the plurality of users using the modified users scores for the plurality of users; and
sending the digital content to particular ones of the plurality of users based upon the sorting.
14. The computer program product of claim 13 , wherein
the sorting and the sending is performed automatically without user intervention.
15. The computer program product of claim 13 , wherein
the digital content is sent to the particular ones of the plurality of users based upon the particular ones of the plurality of users having user scores that exceed a threshold user score.
16. The computer program product of claim 13 , wherein
the plurality of content topics and the user topics are normalized.
17. The computer program product of claim 13 , wherein
the sorting creates a sorted list, and
the sorted list expires after a predetermined amount of time.
18. The computer program product of claim 13 , wherein
the user activities include at least one of a status update, a wiki edit, and a browsing activity.
