Descripción

Geo-WordNet 3.0 connects WordNet synsets with their geographical coordinates (latitude and longitude). In the new 3.0 version, the source of geographical data was Geonames (http://www.geonames.org). Therefore, it was possible to assign to every synset a Geonames ID, together with the coordinates. Geo-WordNet is constituted of a plain text file where every line contains the following fields: <synset offset> <geonames ID> <latitude> <longitude>, separated by a tabulation character. The synsetoffsets used in Geo-WordNet 3.0 correspond to those included in WordNet 3.0.

Funcionalidad

Geo-WordNet extends WordNet with geographical data, allowing all WordNet-based applications to associate spatial information to un-structured texts.

Tecnología

Geo-WordNet 3.0 has been developed in Java using the MIT Java WordNet Interface (MIT JWI), with data from WordNet 3.0 and Geonames. Geographical data were loaded into a PostgreSQL database.

Requisitos técnicos

The only requirement is WordNet 3.0 as a reference for synset offsets.

Módulos

The distribution is a tar.gz file including a folder named “GeoWN3.0″, which contains the following files: 00README.txt, LICENSE,  mapping.dat,  mapping.txt,  not_mapped.txt. Main data are contained in the “mapping.dat” file, while “mapping.txt” and “not_mapped.txt” contain explications on the associations between WordNet synsets and Geonames IDs.

Innovación

Geo-WordNet is the only resource associating geographical information to synsets.
