Abstract

A method of providing a context based service is performed by a user terminal. The method includes: generating a user profile about at least one entity; providing user profile characteristic information obtained or inferred from the user terminal associated with the at least one entity; and controlling to provide a user description generated based on the user profile and the user profile characteristic information to a recommendation engine for a required service if a recommendation of a context based service is required to the at least one entity, the recommendation engine performing a service recommendation according to a situation of the at least one entity.

Claims

1. A context based system comprising:

a user description manager; and

a user terminal connected to the user description manager,

wherein the user description manager is configured to;

generate a user profile about at least one entity through the user terminal;

provide user profile characteristic information obtained or inferred from the user terminal associated with the at least one entity; and

generate a user description based on the user profile and the user profile characteristic information to provide the user description to a recommendation engine performing a service recommendation according to a situation of the at least one entity for a required service if a recommendation of a context based service is required for the at least one entity,

wherein generating the user profile comprises generating a corresponding user profile through a user terminal associated with other entity included in a plurality of heterogeneous entities or an external entity other than the plurality of the heterogeneous entities for a part of the plurality of the heterogeneous entities when the at least one entity comprises the plurality of the heterogeneous entities, and

wherein the user profile characteristic information comprises;

(1) a user usage history representing an action history on a specific domain for the at least one entity, wherein the action history comprises at least one of a content usage history, website usage pattern, and purchase record;

(2) a user preference comprising content consumption information by the at least one entity, wherein the content consumption information comprises a filtering, searching or reading record for a content;

(3) at least one of an audio presentation preference related to an audio play, a display presentation preference related to an image display, and a graphic presentation preference related to a graphic media expression according to the required service;

(4) a user emotion included in an emotion word set and generated based on input data directly inputted by the at least one entity or inference data inferred through sensing by the user terminal; and

(5) a user emotion group comprising a user emotion status of the at least one entity generated during a specific period, the user emotion status being defined as an emotion set representing a mixed emotion.

2. A context based system comprising:

a user description manager; and

a user terminal connected to the user description manager,

wherein the user terminal is configured to receive a user description generated by the user description manager based on a user profile and user profile characteristic information if a recommendation of a context based service is required for at least one entity, and

wherein the user description manager configured to perform a service recommendation according to a situation of the at least one entity for a service required based on the user description and generate the user profile, and

wherein generating the user profile comprises generating the user profile with respect to the at least one entity through the user terminal and the user profile characteristic information being obtained or inferred from the user terminal associated with the at least one entity, and generating a corresponding user profile through a user terminal associated with other entity included in a plurality of heterogeneous entities or an external entity other than the plurality of the heterogeneous entities for a part of the plurality of the heterogeneous entities when the at least one entity comprises the plurality of the heterogeneous entities,

wherein the user profile characteristic information comprises;

(1) a user usage history representing an action history on a specific domain for the at least one entity, wherein the action history comprises at least one of a content usage history, website usage pattern and purchase record;

(2) a user preference comprising content consumption information by the at least one entity, wherein the content consumption information comprises a filtering, searching or reading record for a content;

(3) at least one of an audio presentation preference related to an audio play, a display presentation preference related to an image display, and a graphic presentation preference related to a graphic media expression according to the required service;

(4) a user emotion included in an emotion word set and generated based on input data directly inputted by the at least one entity or inference data inferred through sensing by the user terminal; and

(5) a user emotion group comprising a user emotion status of the at least one entity generated during a specific period, the user emotion status being defined as an emotion set representing a mixed emotion.
