BabelNet
BabelNet is both a multilingual encyclopedic dictionary, with lexicographic and encyclopedic coverage of terms, and a semantic network which connects concepts and named entities in a very large network of semantic relations, made up of about 15 million entries, called Babel synsets. Each Babel synset represents a given meaning and contains all the synonyms which express that meaning in a range of different languages. Its evolution, BabelNet live, is a new, continuously growing resource, thanks to being fed with everyday updates from all the sources it is composed of, including Wikipedia, Wiktionary, users' input, etc.
