Wrapper for CLAVIN (Cartographic Location And Vicinity INdexer) by Berico Technologies. Description from the website: CLAVIN (Cartographic Location And Vicinity INdexer) is an award-winning open source software package for document geotagging and geoparsing that employs context-based geographic entity resolution.
It extracts location names from unstructured text and resolves them against a gazetteer to produce data-rich geographic entities.
CLAVIN does not simply look up location names – it uses intelligent heuristics to identify exactly which Springfield (for example) was intended by the author, based on the context of the document. CLAVIN also employs fuzzy search to handle incorrectly-spelled location names, and it recognizes alternative names (e.g., Ivory Coast and Côte d'Ivoire) as referring to the same geographic entity.
By enriching text documents with structured geo data, CLAVIN enables hierarchical geospatial search and advanced geospatial analytics on unstructured data.
