Apparatus and method for measuring contents similarity based on feedback information of ranked user and computer readable recording medium storing program thereof
First Claim
1. An apparatus for measuring contents similarity based on feedback information from ranked users, comprising:
- at least one processor to provide;
a user ranking unit configured to receive from a database information on users as contents creators and feedback information on posts as contents and rank the users based on the received information;
a user grouping unit configured to classify the users into a plurality of ranked user groups based on the ranking result;
a sequence modeling unit configured to obtain feedbacks from the plurality of ranked user groups and model the contents as sequences of data points based on the feedbacks, each of said data points comprising a preference for the contents of one of said posts as a function of a group ranking of a respective said user group; and
a post similarity calculation unit configured to measure similarity between the modeled sequences to obtain similarity of the posts.

Abstract
An apparatus for measuring contents similarity based on feedback information from ranked users includes: a user ranking unit for receiving from a database information on users as contents creators and feedback information on contents and ranking the users based on the received information; and a user grouping unit for classifying the users into a plurality of groups based on the ranking result. The apparatus further includes: a sequence modeling unit for receiving from the database the contents and the feedback information and modeling the number of feedbacks as sequences based on the ranked user groups; and a post similarity calculation unit for measuring similarity between the modeled sequences.

9. A method for measuring contents similarity based on feedback information of ranked users, comprising:
-
receiving, by a processor, information on users as contents creators and feedback information on posts as contents from a database of a contents similarity measuring apparatus and ranking the users based on the received information; classifying, by a processor, the users into a plurality of ranked user groups based on the ranking result; obtaining feedbacks from the plurality of ranked user groups and modeling, by a processor, the contents as sequences of data points based on the feedbacks, each of said data points comprising a preference for the contents of one of said posts as a function of a group ranking of a respective said user group; and measuring, by a processor, similarity between the modeled sequences to obtain similarity between the posts. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A computing device storing a program for performing a method for measuring contents similarity via a wire/wireless communication network, the program including stored instructions executable by the computing device for:
-
receiving information on users as contents creators and feedback information on posts as contents from a database of a contents similarity measuring apparatus and ranking the users based on the received information; classifying the users into a plurality of ranked user groups based on the ranking result; obtaining feedbacks from the plurality of ranked user groups and modeling the contents as sequences of data points based on the feedbacks, each of said data points comprising a preference for the contents of one of said posts as a function of a group ranking of a respective said user group; and measuring similarity between the modeled sequences to obtain similarity between the posts.
