Edinburgh Geoparser


A place name in a text may have more than one potential referent (e.g. Peru the country vs. Peru the city in Indiana). The Edinburgh Geoparser is a system to automatically recognise place names in text and disambiguate them with respect to a gazetteer. The geoparser can be used with several gazetteers including Unlock and GeoNames. It can also be used to process a variety of input text processes. The demonstration version displays output with a Google maps visualisation. Edina's Unlock text/places service provides another demonstration version. An open source release is planned for 2011.

The Edinburgh Geoparser has been developed as part by a number of projects and applied to a range of data sets:
