Abstract: A method and apparatus for providing positional information using wireless fidelity (WiFi) information is provided. A method of providing positional information at a mobile terminal may include collecting WiFi access point (AP) information by scanning for a WiFi AP in a vicinity of the mobile terminal, extracting facility information associated with a facility associated with the WiFi AP, and determining the positional information of the mobile terminal based on the extracted facility information.

Abstract: Disclosed is a location information determining method and system for providing a variety of services based on a location. The location information determining method includes receiving cell information; and determining location information that matches the cell information as location information of a mobile terminal from a location information database that stores location information that matches a plurality of pieces of cell information, respectively.

Abstract: A method and apparatus for providing positional information using wireless network information is provided. A method of providing positional information at a mobile terminal may include collecting WI-FI access point (AP) information by scanning for a WI-FI AP in a vicinity of the mobile terminal, extracting facility information associated with a facility associated with the WI-FI AP, and determining the positional information of the mobile terminal based on the extracted facility information.

Abstract: A synchronous script lazy loader generates a plurality of virtual functions. Each one of the plurality of virtual functions corresponds to one of a plurality of script modules. The plurality of script modules may be associated with a script. The synchronous script lazy loader loads each of the plurality of virtual functions into a storage space. The synchronous script lazy loader loads a desired one of the plurality of script modules into a memory from the storage space. The synchronous script lazy loader executes the desired script module from the memory when a corresponding one of the plurality of virtual functions is requested for initial execution.

Abstract: Methods and systems of obtaining an advertisement based on event occurrence on a mobile terminal are provided. A desired event is determined to have occurred on the mobile terminal. Event occurrence information is generated. The event occurrence information may be associated with the desired event. A keyword is extracted, which is based on the generated event occurrence information. An advertisement is obtained that is based on the extracted keyword.

Abstract: Methods and systems of modifying content displayed by a mobile device are provided. A region of interest (ROI) of a user is recognized. The ROI may be associated with content being displayed on a display of the mobile device. A time duration of interest based on the ROI is determined. The displayed content is modified based on the ROI, the time duration of interest, and a content type of the displayed content.
