One of my most fruitful project while working at Yahoo! Research was a collaboration with the Yahoo! Image Search team. We built system for extracting and ranking points of interest for towns, countries and regions. The points of interest were extracted from Wikipedia, Yahoo! GeoPlanet and Yahoo! Travel. The ranking was based on co-occurrence statistics from Flickr photos and Yahoo! Image Search query logs. The resulting data package was generated by the research team and applied by Yahoo! Image Search to provide enhanced browsing of search results for towns, countries and regions.
