  • Publication number: 20110145235
    Abstract: 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.

  • Publication number: 20100283693
    Abstract: A wireless terminal antenna is disclosed. The antenna includes a pull rod, a pull rod pedestal located at the base of the pull rod, and a spiral coil. One end of the spiral coil is electrically connected with the pull rod pedestal. The pull rod is axially retractable along the pull rod pedestal until it is retracted into the space enclosed by the spiral coil. At idle time, the pull rod is nested inside the spiral coil so that it is short and portable. When receiving signals normally, the pull rod can be pulled out. The antenna is miniaturized, portable, and provides good performance.

  • Publication number: 20100185663
    Abstract: 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.
