Abstract

We present YAGO2, an extension of the YAGO knowledge base with a focus on temporal and spatial knowledge. It is automatically built from Wikipedia, GeoNames, and Word- Net, and contains nearly 10 million entities and events, as well as 80 million facts representing general world knowl- edge. An enhanced data representation introduces time and location as first-class citizens. The wealth of spatio-temporal information in YAGO can be explored either graphically or through a special time- and space-aware query language.
