Publication number: 20110145235Abstract: A method determines core geographical information in a document by computing a score for each geographical name found in the document. The computation of the score uses the appearance frequency of the respective geographical name and positional weights assigned to various types of appearance positions of the geographical name in the document. The system determines the core geographical information in the document based on the scores of the geographical names found in the document. The method may further compute aggregated scores of geographical regions related to the geographical names and determine the core geographical information using both the aggregated scores of geographical regions and the scores of individual geographical names to increase accuracy.Type: ApplicationFiled: August 28, 2009Publication date: June 16, 2011Inventors: Guo Ping Lei, Chuan Wen Chen, Xiao Shuan Li, Wei Jia Liu, Na Ma, Ming You Wang, Xuan Wang, Hong Xi Zhou
