Abstract: A module and method for determining a named entity of a terminology using a named entity dictionary and a mining rule combined with an ontology schema is provided. The module includes a named entity dictionary and mining rule database storing the named entity dictionary and a mining rule database; a mining pattern generation unit recognizing a terminology from a text and converting the terminology into a mining pattern; a named entity and mining rule search unit searching for a corresponding named entity and a mining rule respectively from the named entity dictionary and the mining rule database using the recognized terminology and the mining pattern; and a names entity selection unit selecting, if two or more named entities corresponding to the recognized terminology are searched, a named entity matching to the concept configuring the RDF triple of the searched mining rule as a named entity of the terminology among the searched named entities.

Abstract: An apparatus and method for updating a named entity dictionary or a mining rule database using the named entity dictionary and a mining rule combined with an ontology schema is provided. The apparatus includes a named entity dictionary and mining rule database storage module storing the named entity dictionary and a mining rule database; a mining pattern generation module recognizing a terminology from a text and converting the terminology into the mining pattern; a named entity and mining rule search module searching for a corresponding named entity and a mining rule from the named entity dictionary and the mining rule database using the recognized terminology and the mining pattern; and a named entity dictionary update module estimating a named entity of the terminology using the mining rule and storing the estimated named entity of the terminology in the named entity dictionary depending on a user's selection.

Abstract: A personalized service system and method based on an ontology is provided, in which if a user selects a personalized service while a subject or an object in a user profile ontology of user's personal information is associated with a subject or an object of a personalized service ontology through a relationship name, the system and method searches for a personalized service ontology corresponding to the selected personalized service, acquires personal information of an instance form in the user profile ontology associated with the personalized service ontology, executes the personalized service by applying the acquired personal information, and provides the user with a result of the execution.

Abstract: RDF network construction device and method using an ontology schema having class dictionaries and mining rules are provided. The RDF network construction device includes an ontology schema storing module, a class managing module, a mining rule managing module, a mining pattern creating module, and an RDF triple creating module.

Abstract: Question-answer service system and method based on RDF search are provided. The question-answer service method includes: extracting a subject. a predicate, and an object from a text document composed of the unstructured sentences not having the structured format; creating RDF models composed of the extracted one subject, one predicate, and one object; determining whether there is semantic collision by comparing the RDF models; receiving a question including the subject S, the predicate P, or the object O from a user and being requested to search, on the basis of the constructed RDF network; creating a question for search by interpreting the input question;. searching an RDF model matching with the question for search through the RDF network; and providing a subject S, a predicate P, or an object O. which corresponds to an answer for the question from the searched RDF model.

Abstract: Related search service system and method based on the RDF network are provided. The related search service method includes: extracting a subject, a predicate, and an object from a text document composed of the unstructured sentences not having the structured format; creating RDF models composed of the extracted one subject, one predicate, and one object: determining whether there is semantic collision by comparing the RDF models; constructing an RDF network by separating the RDF models when there is semantic collision in the RDF models, and integrating the RDF models when there is no semantic collision; and providing service for searching the subjects or the objects which have the same predicate on the basis of the created RDF network.

Abstract: A button apparatus and a mobile appliance having the same are provided. A button cover plate having button areas forms an external portion of a case of the appliance. The button areas may be flat on the surface of the button cover plate 36, and include compression bosses on a rear side thereof that contact and manipulate corresponding switches mounted on a substrate. The button cover plate may be seated in a button recess formed on the case 10. When so arranged, the button apparatus does not project from an outer surface of the mobile appliance, and an external design of the mobile appliance may be varied.

Abstract: The present invention relates to a portable digital device. According to an embodiment, the method comprises a main unit including a display provided on the main unit and a terminal insertion portion; and an auxiliary unit including a terminal portion configured to be electrically connectable to the terminal insertion portion to allow communication between the main unit and the auxiliary unit, the auxiliary unit being configured to control operation of the main unit when being mounted to the main unit, the auxiliary unit being capable of independently reproducing audio and/or video data when being separated from the main unit.

Abstract: The present invention relates to a mobile device. In the present invention, a speaker is installed to a seating portion formed on a rear surface of a main body. The speaker is rotatably installed to the main body, so that the main body can be selectively stably supported on the ground. Also, an insertion portion is concavely formed in one surface of the main body, and a support plate is inserted into the insertion portion to support the main body on the ground. In addition, a hanger is coupled to an outside of the main body so that the main body is caught to an external article. According to the present invention, a better design for an external appearance is provided to the mobile device and convenience of a user is enhanced since the mobile device can stand by the speaker or the support plate. In addition, the main body can be caught to a collar of a user or a hook, whereby the user can easily carry the mobile device.
