Abstract: A method for providing an optimal path through a computer network includes predicting a subsequent action of a target user through an optimal path prediction model that is trained in a form of a graph representing a user action trajectory of a session unit and recommending a path of the predicted action as an optimal path. The recommendation includes identifying a user intent based on a previous action trajectory of the target user in a current session, and guiding a path corresponding to the user intent as one of the optimal paths.

Abstract: A method for providing an optimal path to achieve a user goal includes collecting user historical session data that includes a user action trajectory based on a session unit; and generating a model for optimal path prediction by representing the user historical session data as a path in a form of a graph and by learning the path.

Abstract: Provided is a method for displaying a wallpaper that includes setting a broadcast picture display function to display a specific broadcast picture as a wallpaper in response to a user's request; changing a standby mode to a digital broadcasting reception mode at preset time intervals to periodically capture a picture from a digital broadcast delivered on a specific channel if the broadcast picture display function is set; and displaying the captured picture as a wallpaper for the digital broadcasting reception terminal. The digital broadcasting reception terminal can periodically capture a picture from a digital broadcast program currently delivered and display the captured picture as a wallpaper even when the user does not view the digital broadcast program.

Abstract: An apparatus and method for acquiring a code image in a portable terminal includes an image recognizing unit for acquiring a picture including the code image and a code analyzing unit for verifying color information items for pixels with respect to the acquired picture, deleting a certain color information item according to a predetermined scheme when there are a plurality of color information items in order to recognize the code image having at least one of a QR code and a bar code.

Abstract: A method for displaying broadcasting channel information in a digital broadcasting reception apparatus includes receiving and storing digital broadcasting program guidance data including image information for digital broadcasting programs; generating a broadcasting program list including image information for digital broadcasting programs according to channels when a request for broadcasting channel information is received from a user, by means of the digital broadcasting program guidance data; and displaying the broadcasting program list according to channels, which includes the image information. In the method, it is possible to provide users with graphic-based broadcasting channel information instead of text-based broadcasting channel information. In the method, broadcasting channel information is provided to users together with contents of preview dynamic images or still images for digital broadcasting programs, so that the users view image information for broadcasting programs in advance.
