Referring to FIG. 1, a multimedia content status information-based content search apparatus (hereinafter referred to as a "device") 100 receives content information corresponding to a search query as a search query is transmitted from various multimedia playback terminals 10 And provides a search result to the multimedia playback terminal 10. [

At this time, the search query may be composed of at least one keyword, and the search query may be in an incomplete form. For example, when the search query includes the keyword "A, B ", it is determined whether the search intention of the user is to search for contents containing both A and B at once or to search for a separate content It is important to know whether the That is, since the search query of the user can be composed of keywords in which important parts are omitted, in this case, information for accurately grasping the search intention of the user may be insufficient.

At this time, the apparatus 100 according to an exemplary embodiment of the present invention may supplement the search query of an incomplete user by using the stored information of the situation information. In other words, the device 100 does not merely transmit general content information corresponding to a search query of an incomplete user, but rather receives context information on the content in advance from the administrator terminal 20 and constructs the information as content information, Upon receiving a search request from the terminal 10, the terminal 10 searches for general context information as well as context information and transmits the search result to the multimedia playback terminal 10.

The multimedia playback terminal 10 receives a keyword from a user to retrieve a desired multimedia content, and transmits the keyword to the device 100. Also, the search result is received from the device 100 and is provided in a form that the user can view.

The administrator terminal 20 may be any terminal that is connected to the device 100 and is capable of storing the status information inputted from the administrator in the content information storage unit 110. [

The apparatus 100 includes a content information storage unit 110, a content information management unit 120, a search execution unit 130, and a search output unit 140.

The content information storage unit 110 may include an ontology and a knowledge base. The ontology means a schema region expressing the properties of the class and the relationship between the classes, and the knowledge base can mean a data region representing the actual data. According to an embodiment of the present invention, general information and context information of the multimedia contents are stored in an ontology form. That is, it may be an ontology extended to context information, rather than an ontology graph using general information.

FIG. 2 is a diagram illustrating an example of an ontology including context information according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 2, the general information of multimedia contents refers to attributes representing contents such as a content name, a genre, a director, and an actor. The context information of the multimedia contents includes the characteristics of the characters such as the names, occupations, abilities of the characters appearing in the contents and the relationship information between the characters.

Also, the content information can have a hierarchical structure, and the upper concept is a structure including a lower concept.

3 is a diagram illustrating an example of a hierarchical structure of multimedia contents according to the present invention.

Referring to FIG. 3, the upper concept, a sub-concept, may include various sub-items such as doctors, lawyers, politicians, entrepreneurs, teachers, and the like.

The content information management unit 120 receives status information on a specific content from the administrator terminal 20. The content information management unit 120 manages relevant content information when new multimedia contents are added periodically or existing multimedia contents are deleted periodically. That is, when new multimedia contents are added, the multimedia contents information (general information + situation information) is converted into an ontology form and added to the contents information storage, and related information is also deleted when the existing multimedia contents are deleted.

The content search execution unit 130 interprets the user search term inputted using the content information and generates a search result. The user search statement is composed of a series of keywords separated by a blank, and the search keyword can be composed of general information of contents and situation information.
