Abstract: A portable device is configured to display disaster and safety information and a method is configured to control the portable device to display the disaster and safety information. The portable device includes a global positioning system (GPS) module for receiving position information of the portable device and an information receiving module for receiving the disaster and safety information. A sensor module of the portable device detects an inclination of the portable device and the processor module of the portable device visualizes the disaster and safety information in a first person view or a third person view according to the sensed inclination. A display module of the portable device displays the disaster and safety information based on weather prediction information and/or forest fire damage prediction information.

Abstract: The purpose of the present invention is to display disaster and safety information. To this end, the present invention comprises: a global positioning system (GPS) module for receiving position information of a portable device; an information receiving module for receiving disaster and safety information; a sensor module for sensing tilting of the portable device; a processor module for visualizing the disaster and safety information from a first person point of view or a third person point of view according to the sensed tilting value; and a display module for displaying the disaster and safety information.

Abstract: A system and method for improving performance of unstructured text extraction. The system includes an unstructured data processing unit configured to extract time information or space information in which an event keyword and an event have been generated by performing a linguistic analysis on collected unstructured text and to generate extraction knowledge candidates by mapping the time information or space information to the event keyword and a filter unit configured to determine the validity of the extraction knowledge candidates generated by the unstructured data processing unit using spatiotemporal association structured data.
