I'm happy to offer up a full REST-ful API service for developers wishing to search for Wikipedia articles by location. The data is gathered by downloading the Wikipedia database on a weekly basis and then parsing all of the geocoded entries. This data is then stored in a database where it is able to be accessed via the API. At present, there are over 3.5 million entries covering 36 different languages and this number increases every week.

Gisgraphy is a free and open source framework that provides fulltext search and find nearby services for places on earth (aka : toponyms) from several databases (aka : gazeteers) on the Web (mainly Geonames, but not only : ESRI for instance). It provides an importer to inject the data into a strongly typed Postgres / Postgis database and use them via 2 webservices or a java API : geolocalisation and fulltext in many format (XML, json, PHP, ruby, python, Atom, RSS / GeoRSS).

DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to make sophisticated queries against Wikipedia, and to link other data sets on the Web to Wikipedia data.
