BabelNet is an innovative multilingual encyclopedic dictionary, with wide lexicographic and encyclopedic coverage of terms, and a semantic network/ontology which connects concepts and named entities in a very large network of semantic relations, made up of about 20 million entries.

Each BabelNet synset represents a given meaning and contains all the synonyms which express that meaning in a range of different languages.

BabelNet is provided as a stand-alone resource with its Java API, a SPARQL endpoint and a Linked Data interface as part of the Linguistic Linked Open Data Cloud (LLOD Cloud) cloud.
