CLAVIN is an award-winning open source software library for document geotagging and geoparsing that employs context-based geographic entity resolution. It automatically extracts place names from text documents and intelligently resolves those names against a gazetteer, disambiguating ambiguous references like "Springfield" based on the surrounding context and enhancing the original unstructured text with data-rich geospatial entities corresponding to the places mentioned in the document. In this tech talk, Charlie Greenbacker, CLAVIN's creator, will describe how the software works, demonstrate a simple application based on CLAVIN, and discuss how it can be used to enable geospatial analysis on unstructured text.
