Title: Location Extraction from Social Networks with Commodity Software and Online Data Authors: George Valkanas, Dimitrios Gunopulos Conference: SSTDM @ ICDM 2012 Location is a key ingredient for a huge variety of applications, including Location-Based services, news reporting, disaster management, etc. However, location is also a scarce commodity, because not all people are willing to disclose it, and in most of the cases it is given in textual format, which can not be directly used with other components. In cases like this, we need to geocode location information, i.e., convert textual information to a pair of (latitude, longitude) coordinates. In our current work, we implement a geocoding framework, that takes textual location and returns a GPS signal. To achieve this, we use online data sources and commodity software, since probing external gazetteers would be prohibitive. Our proposed system is both efficient and effective, especially when one considers the information that we rely upon.
