Abstract

The present invention relates to a content recommendation method in which pieces of information collected over an IP Multimedia Subsystem (IMS) network are analyzed through data mining, a semantic pattern is identified from the information and described based on ontology, the characteristics of content to be offered are recorded in ontology and language morphological pattern, and a recommendation filter in terms of various viewpoints and methods is operated in an integrated recommendation framework, thus enabling content recommendation suitable for various contexts to be performed.

The method includes the steps of receiving user information, creating personal preference information based on the user information, deciding a recommendation strategy based on the preference information for content, combining recommendation functions using the recommendation strategy and the content information, personalizing recommendation results with respect to the combination, and providing the personalized content information.

Furthermore, the method for recommending content with context awareness according to the present invention has an advantage in that it can offer more efficient and accurate content to mobile terminal users as a mobile communication network is expanded into an IMS basis and opened and therefore the types and number of content accessible by mobile terminals as well as mobile phones increase abruptly. Furthermore, the method for recommending content with context awareness according to the present invention is advantageous in that it can analogize the life pattern of a mobile terminal user, etc. based on the user'"'"'s current context information and offers content matching the inferred life pattern at the right time and place.

Claims

1. A method for recommending content with context awareness in an IP Multimedia Subsystem (IMS), the method comprising the steps of:

receiving user information;

creating personal preference information based on the user information;

deciding a recommendation strategy based on the preference information for content;

combining recommendation functions using the recommendation strategy and the content information;

personalizing recommendation results with respect to the combination; and

providing the personalized content information.

2. The method as claimed in claim 1, wherein the user information comprises one or more of static information, which is profile information registered when the user subscribes to a service, and dynamic information selected according to the user'"'"'s current context.

3. The method as claimed in claim 1, wherein the personal preference information comprises one or more of content information preferred by the user, and the user'"'"'s social relation network information.

4. The method as claimed in claim 1, wherein the recommendation strategy comprises one or more of a content-based recommendation method and an ontology-based recommendation method.

5. The method as claimed in claim 4, wherein the recommendation strategy comprises the steps of:

determining whether the personal preference information has been stored;

selecting a recommendation group according to the decision results;

assigning a weight to a recommended content according to the selected recommendation group; and

selecting one or more of the content-based recommendation method and the ontology-based recommendation method by analyzing the assigned weight.

6. The method as claimed in claim 5, wherein the recommendation group comprises:

a personal preference group including content information preferred by the user;

a representative preference group in which the user'"'"'s profile information and a similar user group'"'"'s content information are gathered statistically; and

a social relation group in which content information of one or more second users selected according to the user'"'"'s social relation network is gathered statistically.

7. The method as claimed in claim 4, wherein the content-based recommendation method comprises the steps of:

creating a content list preferred by the user based on the user information;

collecting content information corresponding to the content list;

matching the collected content information and the content list; and

deciding a priority of the matched results and providing content corresponding to the decided priority.

8. The method as claimed in claim 4, wherein the ontology-based recommendation method comprises the steps of:

collecting semantic content information, user ontology information and user context information;

performing rule-based inference based on the semantic content information, the user ontology information and the user context information;

creating a semantic rule through the rule-based inference;

creating preference results by inferring the semantic rule; and

deciding a priority of the preference results and providing content corresponding to the decided priority.
