YAGO3

YAGO3 is an extension of the YAGO knowledge base that combines the information from the Wikipedias in multiple languages.  YAGO3 taps into multilingual resources of Wikipedia, getting to know more local entities and facts. In the current version, it has been extracted from 10 different Wikipedia versions (English, German, French, Dutch, Italian, Spanish, Polish, Romanian, Persian, and Arabic).

  1. YAGO3 contains canonical representations of entities appearing in different Wikipedia language editions.
  2. YAGO3 integrates all non-English entities into the rich type taxonomy of YAGO.
  3. YAGO3 provides a mapping between non-English infobox attributes and YAGO relations.

YAGO 2.5 (aka. YAGO2s)

YAGO2s is an improved version of YAGO 2, with the following main characteristics:

  1. YAGO2s is stored natively in Turtle, making it completely RDF/OWL compliant while still maintaining the fact identifiers that are unique to YAGO.
  2. The YAGO2s architecture enables cooperation of several contributors, facilitates debugging and maintenance. The data is divided into themes, so that users can download only particular pieces of YAGO ("YAGO à la carte").
  3. YAGO2s contains thematic domains such as "music" or "science", which gives a topic structure to YAGO.

YAGO 2

YAGO 2 is an improved version of the original YAGO. Its main characteristics are:

  1. As with all major releases, the accuracy of YAGO2 has been manually evaluated, proving a confirmed accuracy of 95%. Every relation is annotated with its confidence value.
  2. YAGO2 is an ontology that is anchored in time and space. YAGO2 attaches a temporal dimension and a spacial dimension to many of its facts and entities.
  3. YAGO2 is particularly suited for disambiguation purposes, as it contains a large number of names for entities. It also knows the gender of people.
