RoWordNet stand for Romanian WordNet, a semantic network for the Romanian language . RoWordNet mimics Princeton WordNet, a large lexical database of English. The building block of a WordNet is the synset that expresses a unique concept. The synset (a synonym set) contains, as the name implies, a number of synonym words known as literals. The synset has more properties like a definition and links to other synsets. They also have a part-of-speech (pos) that groups them in four categories: nouns, verbs, adverbs and adjectives. Synsets are interlinked by semantic relations like hypernymy ("is-a"), meronymy ("is-part"), antonymy, and others.
