Abstract

A method of classifying contents comprising configuring one or more categories in a hierarchical structure, mapping one or more contents and the one or more categories based on at least one piece of information on the one or more contents and information on the one or more categories, and updating the hierarchical structure of the categories based on a preset condition when content-related information of each category determined according to the mapping meets the preset condition.

First claim

What is claimed is:

1. A method of classifying at least one image in an electronic device having an electronic processor, a display, and a memory storing one or more contents comprising the at least one image, one or more contents, the method comprising:
storing, in the memory, information related to a plurality of categories forming a hierarchical structure;
mapping via the electronic processor, each of the at least one image from the memory to one among the plurality of categories based on at least one piece of information on the at least one image and information on the plurality of categories;
when content-related information of a specific category of a plurality of categories determined according to the mapping meets a preset condition related to a number of images mapped to the specific category, modifying, via the electronic processor, the hierarchical structure associated with the specific category, wherein modifying the hierarchical structure of the categories comprises:
merging the specific category into a higher category in the hierarchical structure when a number of contents of the specific category is less than a first preset number, and
classifying the specific category into one or more lower categories in the hierarchical structure when the number of contents of the specific category is greater than a second preset number; and

in response to a request for displaying the at least one image, displaying, via the display, the at least one image based on the modified updated hierarchical structure,
wherein the updated hierarchical structure reduces deviation of a number of images mapped to one or more categories of the plurality of categories after reclassifying the categories in the updated hierarchical structure.

2. The method of claim 1 , further comprising displaying lists of the one or more images based on the modified hierarchical structure of the categories.

3. The method of claim 1 , wherein the content-related information of each category is at least one selected from a number of contents mapped to each category, capacities of contents mapped to each category, and proportions of one or more objects included in the contents mapped to each category.

4. The method of claim 1 , wherein the preset condition further comprises at least one selected from a condition in which a number of contents mapped to each category is different from a preset number, a condition in which the number of contents mapped to each category is greater than the preset number, a condition in which the number of contents mapped to each category is less than the preset number, a condition in which capacities of contents mapped to each category are larger than preset capacities, a condition in which the capacities of the contents mapped to each category are smaller than the preset capacities, a condition in which proportions of one or more objects included in the contents mapped to each category are greater than preset proportions, and a condition in which the proportions of the one or more objects included in the contents mapped to each category are less than the preset proportions.

5. The method of claim 4 , wherein the preset number varies depending on each of the one or more categories, and is configured based on at least one selected from a total number of contents mapped to the one or more categories, a total number of categories, and a number of user accesses to the one or more categories.

6. The method of claim 1 , further comprising:
receiving analysis information on one or more contents from a second electronic device; and
identifying categories of the contents based on the analysis information.

7. The method of claim 6 , further comprising:
transmitting one or more contents to the second electronic device; and
receiving analysis information on the transmitted contents from the second electronic device.

8. The method of claim 6 , further comprising receiving the one or more contents and analysis information on the one or more contents from the second electronic device.

9. An electronic device comprising:
a display configured to display at least one image;
a memory configured to store one or more contents comprising the at least one image and information related to a plurality of categories configured in a hierarchical structure; and
a controller configured to:
map each of the at least one image from the memory to one among the plurality of categories based on at least one piece of information on the at least one image and information on the plurality of categories,
when content-related information of a specific category determined according to the mapping meets a preset condition related to a number of images mapped to the specific category, to modify the hierarchical structure associated with the specific category resulting in a different hierarchical structure of categories, wherein modifying the hierarchical structure of the categories comprises:
merging the specific category into a higher category in the hierarchical structure when a number of contents of the specific category is less than a first preset number, and
classifying the specific category into one or more lower categories in the hierarchical structure when the number of contents of the specific category is greater than a second preset number, and

in response to a request for displaying the at least one image, to display the at least one image based on the modified hierarchical structure,

wherein the updated hierarchical structure reduces deviation of a number of images mapped to one or more categories of the plurality of categories after reclassifying the categories in the updated hierarchical structure.

10. The electronic device of claim 9 , further comprising a display unit configured to classify the one or more images according to the modified hierarchical structure of the categories.

11. The electronic device of claim 9 , wherein the content-related information of each category is at least one selected from a number of contents mapped to each category, capacities of contents mapped to each category, and proportions of one or more objects included in the contents mapped to each category.

12. The electronic device of claim 9 , wherein the preset condition further comprises at least one selected from a condition in which a number of contents mapped to each category is different from a preset number, a condition in which the number of contents mapped to each category is greater than the preset number, a condition in which the number of contents mapped to each category is less than the preset number, a condition in which capacities of contents mapped to each category are larger than preset capacities, a condition in which the capacities of the contents mapped to each category are smaller than the preset capacities, a condition in which proportions of one or more objects included in the contents mapped to each category are greater than preset proportions, and a condition in which the proportions of the one or more objects included in the contents mapped to each category are less than the preset proportions.

13. The electronic device of claim 12 , wherein the preset number varies depending on each of the one or more categories, and is configured based on at least one selected from a total number of contents mapped to the one or more categories, a total number of categories, and a number of user accesses to the one or more categories.

14. The electronic device of claim 9 , wherein the controller is further configured to analyze the one or more contents and identify categories of the one or more contents according to the analysis.
