WordNet is a large lexical database of English. Nouns, verbs, adjectives, and suffixes are grouped into a set of cognitive synonyms (syncs), each of which represents a separate concept. Synsets are interconnected using conceptual-semantic and lexical relationships. The resulting network of meaningful words and concepts is managed using a browser. WordNet is also open to the public for download. The WordNet structure is a useful tool fo r the process of computer linguistics and natural languages.
