In addition, Yahoo also announced that, starting today, it will allow developers to download and use the full data set of Yahoo's GeoPlanet. The GeoPlanet data, which contains information about millions of placenames in multiple languages, also forms the basis of Placemaker's geographical knowledge.The GeoPlanet data will be licensed under the Creative Commons Attribution license.
Clustering Billions of Images with Large Scale Nearest Neighbor Search
Image collections on this scale make performing even the most common and simple computer vision, image processing, and machine learning tasks non-trivial. An example is nearest neighbor search, which not only serves as a fundamental subproblem in many more sophisticated algorithms, but also has direct applications, such as image retrieval and image clustering. In this paper, we address the nearest neighbor problem as the first step towards scalable image processing. We describe a scalable version of an approximate nearest neighbor search algorithm and discuss how it can be used to find near duplicates among over a billion images.
