Abstract

An electronic apparatus is configured to: obtain through the communicator characteristic data of each of the external apparatuses regarding a plurality of user characteristics, classify the plurality of external apparatuses into a plurality of groups, whose user characteristic are similar, based on the obtained characteristic data, in response to designating one or more first external apparatuses among the plurality of external apparatuses, calculate similarity of the user characteristic between the first external apparatus and a plurality of second external apparatuses of the group in which the first external apparatus is included among the plurality of groups, and select one or more second external apparatuses whose similarity are relatively high among the plurality of second external apparatuses.

First claim

The invention claimed is:

1. An electronic apparatus comprising:
a communicator configured to communicate with a plurality of external apparatuses, wherein the plurality of external apparatuses are used by a plurality of users respectively having a plurality of user characteristics; and
a processor configured to:
obtain, through the communicator, characteristic data regarding user characteristic of each of the plurality of users from the plurality of external apparatuses,
classify the plurality of external apparatuses users into a plurality of groups based on the obtained characteristic data, wherein user characteristics of users in each of the plurality of groups are similar to each other,
receive a designation of one or more user characteristics among the plurality of user characteristics,
in response to the designation being received, select a group including one or more first users among the plurality of groups, the one or more first users having the one or more user characteristics,
calculate similarity of the user characteristic between the one or more first users and a plurality of remaining users included in the selected group, and
select one or more external apparatuses used by one or more second users whose similarity is relatively high among the plurality of remaining users.

2. The electronic apparatus according to claim 1 , wherein the user characteristic indicates a behavior pattern which is obtained from a use history of a user of an external apparatus among the plurality of external apparatuses.

3. The electronic apparatus according to claim 1 , wherein the characteristic data includes a plurality of unit items regarding a preset plurality of behaviors of a user and an item value which indicates whether the user conducts a behavior of the preset plurality of behaviors.

4. The electronic apparatus according to claim 3 , wherein the processor is further configured to compare item values among a plurality of characteristic data at a preset plurality of bit position, and determine whether the user characteristics are similar among the plurality of characteristic data based on a number of bits which indicate a same value.

5. The electronic apparatus according to claim 1 , wherein the processor is further configured to calculate the similarity of the user characteristic between the one or more first users and the one or more second users by obtaining a centroid of the characteristic data of the one or more first users and calculating similarity to the centroid for each of the characteristic data of the plurality of remaining users.

6. The electronic apparatus according to claim 5 , wherein the processor is further configured to calculate a Euclidean distance between the characteristic data of the plurality of remaining users and the centroid, and select one or more second users whose Euclidean distance is smaller than a threshold as the one or more second users whose similarity is relatively high.

7. The electronic apparatus according to claim 5 , wherein the centroid is an average of coordinate values of the characteristic data of the one or more first users.

8. A method of controlling an electronic apparatus, comprising:
obtaining characteristic data regarding user characteristic of each of a plurality of users from a plurality of external apparatuses, wherein the plurality of external apparatuses are used by the plurality of users respectively having a plurality of user characteristics,
classifying the plurality of users into a plurality of groups based on the obtained characteristic data, wherein user characteristics of users in each of the plurality of groups are similar to each other,
receiving a designation of one or more user characteristics among the plurality of user characteristics,
in response to the designation being received, selecting a group including one or more first users among the plurality of groups, the one or more first users having the one or more user characteristics,
calculating similarity of the user characteristic between the one or more first users and a plurality of remaining users included in the group, and
selecting one or more external apparatuses used by one or more second users whose similarity is relatively high among the plurality of remaining users.

9. The method according to claim 8 , wherein the user characteristic indicates a behavior pattern which is obtained from a use history of a user of an external apparatus among the plurality of external apparatuses.

10. The method according to claim 8 , wherein the characteristic data includes a plurality of unit items regarding a preset plurality of behaviors of a user and an item value which indicates whether the user conducts a behavior of the preset plurality of behaviors.

11. The method according to claim 10 , comparing item values among a plurality of characteristic data at a preset plurality of bit position, and determining whether the user characteristics are similar among the plurality of characteristic data based on a number of bits which indicate a same value.

12. The method according to claim 8 , calculating the similarity of the user characteristic between the one or more first users and the one or more second users by obtaining a centroid of the characteristic data of the one or more first users and calculating similarity to the centroid for each of the characteristic data of the plurality of remaining users.

13. The method according to claim 12 , calculating a Euclidean distance between the characteristic data of the plurality of remaining users and the centroid, and selecting one or more second users whose Euclidean distance is smaller than a threshold as the one or more second users whose similarity is relatively high.

14. The method according to claim 12 , wherein the centroid is an average of coordinate values of the characteristic data of the one or more first users.
