Hence, knowledgebased approaches rely on semantic networks such as WordNet 1 (Miller et al., 1990), a manuallycurated resource where synonyms are grouped into so-called synsets, or BabelNet 2 (Navigli and Ponzetto, 2010), a large multilingual encyclopedic dictionary that merges together different resources like WordNet, Wikipedia, Wikidata etc.
in one form or another both approaches to WSD need lexical-semantic data.
