Abstract

An information processing apparatus includes a communication unit and a control unit. The control unit is configured to control the communication unit to receive a plurality of pieces of post information sent from a first user, to obtain a plurality of pieces of evaluation information of another user with respect to the received plurality of post information, to classify the plurality of pieces of post information into a plurality of clusters, and to determine, as an advantage cluster of the first user, a cluster with the highest evaluation in the plurality of pieces of evaluation information out of the plurality of clusters.

First claim

What is claimed is:

1. An information processing apparatus, comprising:
a communication unit;
a memory configured to store instructions; and
one or more processors configured to execute the instructions stored in the memory, wherein the one or more processors are further configured to:
control the communication unit to receive a plurality of pieces of first post information sent from a first user;
obtain a plurality of pieces of evaluation information of a second user with respect to the received plurality of pieces of the first post information;
classify the received plurality of pieces of the first post information into a plurality of clusters;
determine, as an advantage cluster of the first user, a cluster with a highest evaluation value in the plurality of pieces of evaluation information among the plurality of clusters;
obtain evaluation of the first user with respect to second post information sent from the second user,
classify the second post information into one of the plurality of clusters; and
increase an evaluation value represented by the evaluation of the first user based on a determination that the one of the plurality of clusters into which the second post information is classified and the advantage cluster are the same.

2. The information processing apparatus according to claim 1 , wherein the one or more processors are further configured to classify the plurality of pieces of evaluation information sent from the second user into the plurality of clusters, and determine, as a first favorite cluster of the second user, a cluster with the highest evaluation value out of the plurality of clusters.

3. The information processing apparatus according to claim 2 , wherein the one or more processors are further configured to control the communication unit to send information that represents the first favorite cluster of the second user based on a request from an apparatus used by the first user.

4. The information processing apparatus according to claim 2 , wherein the one or more processors are further configured to control the communication unit to send, to an apparatus used by the second user, recommendation information that recommends to continuously receive the plurality of pieces of the first post information sent from the first user in a based on a determination that the advantage cluster of the first user and the first favorite cluster of the second user are the same.

5. The information processing apparatus according to claim 2 , wherein the one or more processors are further configured to classify the received plurality of pieces of the first post information into one of the plurality of clusters, and control the communication unit so that the received plurality of pieces of the first post information are received by an apparatus used by a user who has a second favorite cluster that is the same as the one of the plurality of clusters into which the second post information is classified.

6. The information processing apparatus according to claim 2 , wherein the one or more processors are further configured to classify commodity information on a determined commodity into one of the plurality of clusters, and output, as an evaluation value of the commodity information, a value obtained by applying weights to evaluation information of different users with respect to the commodity information by a degree of taste of the different users with respect to the one of the plurality of clusters into which the second post information is classified.

7. The information processing apparatus according to claim 2 , wherein the one or more processors are further configured to:
classify one of each of a plurality of pieces of commodity information and each of a plurality of pieces of article information into one of the plurality of clusters,
extract evaluation information, sent from a user whose favorite cluster is the same as the one of the plurality of clusters into which the second post information is classified, out of evaluation information of a plurality of users with respect to one of the plurality of pieces of commodity information and the plurality of pieces of article information, and
generate recommendation information that recommends one of commodity information and article information based on the extracted evaluation information among the one of the plurality of pieces of commodity information and the plurality of pieces of article information.

8. The information processing apparatus according to claim 2 , wherein the one or more processors are further configured to specify a user group as a spam group based on a determination that evaluation in a plurality of pieces of evaluation information with respect to post information sent from a plurality of users belonging to the user group is higher in the user group among a plurality of user groups, the user group including the plurality of users, the plurality of users having a common favorite cluster.

9. The information processing apparatus according to claim 2 , wherein the one or more processors are further configured to generate recommendation information that recommends, for the second user, post information sent from a user, the post information belonging to a second favorite cluster, a determined number or more of users having the second favorite cluster, the second favorite cluster being different from the first favorite cluster of the second user.

10. The information processing apparatus according to claim 2 , wherein the one or more processors are further configured to generate display information that displays number of users for each favorite cluster, the number of users having a common favorite cluster.

11. The information processing apparatus according to claim 2 , wherein the one or more processors are further configured to detect a correlation between a relationship between the first favorite cluster and a second favorite cluster with respect to the first post information, and a relationship between a third favorite cluster and a fourth favorite cluster with respect to the second post information.

12. The information processing apparatus according to claim 1 , wherein the one or more processors are further configured to control the communication unit to send information that represents the advantage cluster of the first user based on a request from an apparatus used by the second user.

13. The information processing apparatus according to claim 1 , wherein the one or more processors are further configured to generate recommendation information that recommends a community based on evaluation value in evaluation information with respect to post information sent from a user belonging to the community, the community including a plurality of users whose favorite clusters are the same.

14. The information processing apparatus according to claim 1 , wherein the plurality of pieces of evaluation information of the second user with respect to the received plurality of pieces of the first post information is obtained based on at least a scroll operation performed by the second user with respect to displayed post information.

15. The information processing apparatus according to claim 14 , wherein the plurality of pieces of evaluation information is measured based on at least one of a scroll speed of the scroll operation or a duration for which the second user stops a scroll on the displayed post information.

16. The information processing apparatus according to claim 1 , wherein the one or more processors are further configured to evaluate the first user based on a combination of overall evaluation of the plurality of pieces of the fir
