Abstract

An apparatus of analyzing a user preference about a domain is provided. The apparatus including a context structure creator configured to analyze a history of a context and to create a context structure that expresses a relationship between contexts, and a context structure matching unit configured to match a current context to the context structure and calculate a context matching value of the current context.

Claims

1. An apparatus of analyzing a user preference about a domain element, comprising:

a context structure creator executing on a hardware processor, the context structure creator being configured to analyze a history of the user'"'"'s contexts associated with the domain element and to create a context structure in a form of a hypercube that expresses a relationship between the user'"'"'s contexts; and

a context structure matching unit configured to match the user'"'"'s current context to the context structure and to calculate a context matching value of the user'"'"'s current context,

wherein the context matching value represents the user preference about the domain element and is calculated in consideration of a frequency of the context matching value being inaccurate by recursively adding a context matching value of a specific level with a context matching value of a parent level of the specific level.

2. The apparatus of claim 1, further comprising a context collector configured to collect the user'"'"'s current context and to store the user'"'"'s current context in a context storage.

3. The apparatus of claim 1, wherein the context structure is created for each element of a domain.

4. The apparatus of claim 1, further comprising a domain preference inquiring unit configured to request a controller to send a user preference value about an element of a domain, in response to a request from an application.

5. The apparatus of claim 4, wherein the controller controls the context structure matching unit to calculate the context matching value, in response to the request from the domain preference inquiring unit.

6. The apparatus of claim 1, wherein the hypercube multi-dimensionally and multi-layeredly representing a kind of context or two or more kinds of contexts associated with each other.

7. The apparatus of claim 6, wherein the context matching value is calculated by multiplying an occurrence frequency of context by a predetermined weight value.

8. The apparatus of claim 7, wherein the predetermined weight value is a level value of the current context.

9. The apparatus of claim 1, wherein the context matching value is calculated based on occurrence frequencies of the user'"'"'s contexts associated with the domain element and the user'"'"'s current context.

10. The apparatus of claim 1, wherein the contexts are expressed numerically.

11. The apparatus of claim 1, wherein the contexts are expressed non-numerically.

12. The apparatus of claim 1, wherein the current context is collected via a sensor, a system service, a user profile, or an Open API.

13. A method of analyzing a user preference about a domain element, comprising:

collecting user'"'"'s contexts associated with the domain element and storing the user'"'"'s contexts in a context storage;

analyzing histories of the user'"'"'s contexts associated with the domain element stored in the context storage and creating a context structure in a form of a hypercube that expresses a relationship between the user'"'"'s contexts; and

matching the user'"'"'s current context to the context structure and calculating a context matching value of the user'"'"'s current context about the domain element,

wherein the context matching value represents the user preference about the domain element and is calculated in consideration of a frequency of the context matching value being inaccurate by recursively adding a context matching value of a specific level with a context matching value of a parent level of the specific level.

14. The method of claim 13, wherein the hypercube multi-dimensionally and multi-layeredly representing a kind of context or two or more kinds of contexts associated with each other.

15. The method of claim 13, wherein the context matching value is calculated by multiplying an occurrence frequency of context by a predetermined weight value.

16. The method of claim 15, wherein the predetermined weight value is a level value of the current context.

17. The method of claim 13, wherein the context matching value is based on occurrence frequencies of the user'"'"'s contexts associated with the domain element and the user'"'"'s current context.

18. A device comprising:

an apparatus of analyzing a user preference about a domain element, comprising;

a context structure creator executing on a hardware processor, the context structure creator being configured to create a context structure in a form of a hypercube that expresses a relationship between the user'"'"'s contexts associated with the domain element; and

a context structure matching unit configured to match a current context of the user to the context structure and to calculate a context matching value of the current context of the user,

wherein the context matching value represents the user preference about the domain element and the context matching value is calculated in consideration of a frequency of the context matching value being inaccurate by recursively adding a context matching value of a specific level with a context matching value of a parent level of the specific level.
