GeoParser is a text analysis tool that may be used to identify, tag and (where appropriate) disambiguate references to geographic location in a text resource. The tool uses Natural Language Processing to analyse the composition of a resource and identifying words that match its geographic database. The approach is useful for processing ambiguous references, such as names that may have one of several locations (e.g. Belfast in Ireland, New Zealand and Canada) and distinguishing names that may be confused with other action (e.g. Reading in Berkshire and reading as an activity). GeoParser may be used with GeoCrossWalk to tag a place name with full geographical coordinates (e.g. an OS National Grid Reference).
