An increasing number of applications are making use of explicit knowledge about words and the entities they represent. This talk presents three data integration methods to obtain such knowledge. The first involves learning models to disambiguate word meanings. The second reconciles equivalence and distinctness information about entities from multiple sources. The third method adds a comprehensive taxonomic hierarchy, reflecting how different entities relate to each other. Together, they can be used to produce a large-scale multilingual knowledge base semantically describing over 5 million entities and over 16 million natural language words and names in more than 200 different languages.
