Abstract: A method for social tagging using a property field of an ontology object includes: selecting an object in an ontology database storing therein objects in forms of classes; selecting a property field in a class corresponding to the selected object; and adding a social tag by storing user's input as a value of the selected property field. Classes stored in the ontology database may have property fields defined when instances of the classes are created, and specific values may be stored as values of the property fields also when the instances are created. The property fields defined when the instances are created are classified into data type property fields and object type property field, and the selected property field is a data type property field.

Abstract: Provided are an apparatus and method for post-processing a dialogue error in a speech dialogue system using multilevel verification, in which both of a user's current utterance and a whole dialogue flow are taken into account through the multilevel verification including speech recognition results analysis, linguistic analysis, discourse analysis and dialogue analysis. As a result, various errors that may occur in the speech dialogue system are detected, and error post-processing appropriate to a detected error type is performed, so that speech recognition errors may be reduced.

Abstract: Provided are a method and apparatus for providing information according to a user's request, and more particularly, an interactive information providing service method and apparatus for analyzing a user's request and providing information corresponding to the request on the basis of a dialog input received from the user.

Abstract: A data transmission method indicating data pending in a ZigBee network is provided, wherein the data transmission method is used to shorten a delay time for data transmission by setting a certain bit to indicate data pending in the ZigBee network to a ZigBee device, the certain bit indicating data pending to an acknowledge frame for acknowledging a data frame from the ZigBee device. The data transmission method according to the present invention includes broadcasting beacons so as to allow the ZigBee coordinator to maintain the connection of the ZigBee network; downloading a data frame from an assigned ZigBee device transmitting the data frame by receiving the beacons; and transmitting an acknowledge frame including a data pending bit indicating data pending to the assigned ZigBee device.

Abstract: The Zigbee device including: a memory storing the neighbor table for writing address information of a device; a controller acquiring the address information of the device present within electrical power enabling Zigbee communication according to a network connection type defined in a Zigbee alliance, writing the address information in the neighbor table, performing a connection to a network via the device, broadcasting the address information assigned through the network connection to the device, and controlling transmission of data to a destination device when address information of the destination device to which the data is to be transmitted is present in the neighbor table; and a transceiver performing the Zigbee communication according to control of the controller.

Abstract: An apparatus and a method for correcting a distorted image is capable of correcting an optical distortion of an image and misconvergence by prewarping an inputted image without using a convergence yoke, and an image displayer using the same. The apparatus for correcting an image distortion for an image displayer in which an image signal is inputted to display an image on a screen and an image distortion is corrected, includes: a reference image generator for generating a predetermined reference image; a camera for inputting the reference image and photographing an image outputted on the screen; and a distortion information extracting unit for comparing the photographed image outputted from the camera and the reference image outputted from the reference image generator, and generating distortion correction information to correct a distortion of the photographed image in case that the image has been distorted.

Abstract: Disclosed is a video display an auto-convergence error in a projection television receiver (TV) capable of preventing generation of an error when an auto-convergence is performed.

Abstract: A homepage searching method uses a similarity recalculation based on a URL substring relationship. An entry point of a homepage is searched among a plurality of web documents belonging to the homepage by using their substring relationships. The technical essence lies in that the present invention uses a principle that if a URL of a certain web document is a substring of a URL of another web document, the former is more likely to be an entry point of a homepage than the latter. Thus, the present invention improves a conventional information searching method and allows a page serving as an entry point of a homepage to be searched prior to other documents. Accordingly, a user can determine whether a searched web document is a homepage or not without visiting all the URLs of the searched web documents.
