A method of operating a location-based system includes identifying geographic information within unstructured electronic text. The identified geographic information, which includes street information, address information, or names of locations is extracted. Candidate geographic locations to which the identified geographic information may refer are determined. One of the candidate geographic locations is selected. An alphanumeric representation of the selected geographic location is utilized in a location-based service. The invented system performs each of the preceding steps. The system supports the extraction of all locations mentioned in the unstructured text, applying the steps mentioned above.
