Lexical database of English word senses and relations
WordNet is a large lexical database of the English language.It organizes English words into groups called "synsets," which contain synonyms that share similar meanings. Each synset represents a specific concept and includes not only synonyms but also various semantic relationships with other words, such as antonyms, hypernyms (more general terms), hyponyms (more specific terms), and meronyms (part-whole relationships).
