摘要: 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.
摘要翻译: 方法通过计算文档中找到的每个地理名称的得分来确定文档中的核心地理信息。 分数的计算使用分配给文档中地理名称的各种类型的外观位置的相应地理名称和位置权重的出现频率。 系统根据文档中找到的地理位置的分数确定文档中的核心地理信息。 该方法可以进一步计算与地名相关的地理区域的聚集分数,并且使用地理区域的聚集分数和个别地名的分数来确定核心地理信息以增加准确度。

摘要: A method and a system provide regional content to users by associating data files with geographical properties and matching the geographical property of a data file with the geographical property of the user. The system extracts geographical information from a data file, and associates the data file with a source geographical property corresponding to the extracted geographical information according to a geographical information database. Upon obtaining a user geographical property of a user, the system provides the data file to the user if the source geographical property matches the user geographical property. The method and the system may be implemented using a geographical name lexicon or a geographical name suffix lexicon.
摘要翻译: 方法和系统通过将数据文件与地理属性相关联并将数据文件的地理属性与用户的地理属性相匹配来向用户提供区域内容。 该系统从数据文件中提取地理信息,并且根据地理信息数据库将数据文件与对应于所提取的地理信息的源地理属性相关联。 在获得用户的用户地理属性时,如果源地理属性与用户地理属性匹配,则系统向用户提供数据文件。 方法和系统可以使用地理名称词典或地理名称后缀词典来实现。
