Abstract: A method for providing a mobile terminal with a software keyboard proper for the language of a country where it is located in a mobile communications network providing global roaming, comprises the steps of constructing a database on the information of multinational software keyboards in a server, transmitting the information on the location of the mobile terminal to the server, and transmitting the information on the proper software keyboard to the mobile terminal by ascertaining the country.

Abstract: The present invention relates to a method for providing answers to a question wherein the quality of the question and answer data posted by users is evaluated to improve the quality of the question and answer in an answer and question service in which the users can ask questions and give answers on the Internet. According to the present invention, there is provided a method for providing answers to a question, which is performed on the Internet, comprising the steps of: receiving a question from a first user, providing the question on a given web page, receiving evaluation data for the question from a second user or an operator of the web page, calculating evaluation result data by reflecting the evaluation data, and providing the evaluation result data on the web page in association with the question.

Abstract: The present invention relates to a method for multi-step filtering a candidate object which is filtered by a minimum bounding rectangle (MBR); and, more particulary, to a method of multi-step filtering a candidate object by employing a minimum maximum point (MMP) filter to improve spatial query filtering process performance by refiltering the candidate objects, which are filtered by using a rotated minimum bounding rectangle (Rotated Minimum Bounding Rectangle) surrounding spatial objects during filtering process at a step of spatial query filtering and refining of spatial database, by using spatial filter, i.e., MMP filter.
