ulex - Unique Location Extractor
Extracts coordinates of an event location from text based
on dictionaries of landmarks, roads, and areas. Only returns
the location of an event of interest and ignores other location
references; for example, if determining the location of a road
traffic crash from the text "crash near [location 1] heading
towards [location 2]", only the coordinates of "location 1"
would be returned. Moreover, accounts for differences in
spelling between how a user references a location and how a
location is captured in location dictionaries. For more
information on the algorithm, see Milusheva et al. (2021)
