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.
