Abstract: Disclosed is a knowledge product trading method of an online store. The knowledge product trading method as an operation method of an online knowledge trading system includes providing a knowledge authoring application (app), collecting knowledge from a knowledge provider through the knowledge authoring app, providing a knowledge service app, receiving a knowledge query request from a knowledge consumer through the knowledge service app, and selling the knowledge collected through the knowledge authoring app in response to the knowledge query request.

Abstract: Disclosed herein is an apparatus and method for analyzing information about floating population. The apparatus includes an information collection unit, a data integration unit, a data mining analysis unit, and an interface unit. The information collection unit collects information about locations provided by mobile communication terminals of moving objects, information about attributes of the moving objects, and information about locations and attributes related to stationary objects. The data integration unit creates integrated data by integrating the information collected by the information collection unit, national statistical information, and map data registered previously. The data mining analysis unit extracts data, consistent with conditions input by a system user, from the integrated data, and searches the map data for based moving patterns of the moving objects using data mining analysis. The interface unit provides a map service in which search results have been applied to the map data.

Abstract: Provided are a system and method for providing a user-specific advertisement on the basis of machine-to-machine (M2M) communication, and a mobile terminal. The method includes: receiving an advertising message broadcasted from at least one mobile terminal; extracting an advertisement according to a user situation using profile information set by a user of the mobile terminal; and presenting and displaying the extracted advertisement.

Abstract: Disclosed herein are a server-sensor network cooperative spatial query processing method and a server using the method. The server-sensor network cooperative spatial query processing method includes the server detecting supplementary information for selecting sensor nodes to be excluded from among a plurality of sensor nodes by performing a preliminary spatial query, before starting a spatial query with the plurality of sensor nodes, and the server requesting the spatial query to the sensor nodes, selected based on the supplementary information, when starting the spatial query with the plurality of sensor nodes.

Abstract: Disclosed herein is an apparatus and method for providing composite sensor information. The apparatus receives sensor information from a plurality of sensors and creating a virtual sensor as a proxy for a plurality of effective sensors included in a region requested to be searched from a user terminal. Thereafter, the apparatus creates composite sensor information by fusing a plurality of the sensor information corresponding to the plurality of effective sensors included in the virtual sensor.

Abstract: Disclosed is a spatial image information method and system for rapid and efficient storage in a relation type database and retrieval and management of spatial images acquired by a combined system of a global positioning system (GPS), an inertial navigation system (INS), and an image acquisition device (i.e., CCD camera). The spatial image acquired by the GPS/INS/CCD camera combined system is combined with an exterior orientation composed of a camera position (x,y,z), accelerated velocity, slope and direction at the moment the image is acquired and an interior orientation acquired by a camera calibration, so that calculation of a specified spatial coordinate information becomes possible.

Abstract: Provided is a system for providing 3-dimensional (3D) vehicle information with a predetermined viewpoint by grasping circumstances such as other vehicles and road facilities in an outside of a user's vehicle, and a method thereof. The system includes: an internal sensing unit for acquiring raw material data used to determine a location of the user's vehicle; an external sensing unit for acquiring raw material data; a storing unit for storing coordinates of roads and major road facilities, and relationship between user's vehicle and the road or the major road facilities; an inferring unit for operating, determining object information and inferring a relationship between vehicles; a rendering unit for reorganizing object data including user s vehicle information determined in the inferring unit in a 3D graphic form; and an output unit for outputting 3D graphic data reorganized in the rendering unit to an output device.
