This is code to populate a database containing Geo-Net-PT02 ontology with Information Content and perform several semantic similarity measures, and perform experiments using a dataset of hand-annotated toponyms.

Geo-CHAVE-PT01.zip is an annotated corpus which was used to evaluate which semantic similarity measure better disambiguates toponyms.
