WordNet is a kind of online English language database. The words are grouped into synonyms and definitions are provided. One could say WordNet combines a dictionary and thesaurus.

Christiane Fellbaum has written:

'WordNet'

Someone who works to protect the environment from destruction or pollution. (WordNet)

"paradigm, epitome, image."

From Babylon, a computer program. More exactly, from WordNet 2.0.

WordNet is a lexical database of English words grouped into sets of synonyms, called synsets, and organized into hierarchies. It links words based on their semantic relationships, such as synonymy, hypernymy (is-a relationships), and hyponymy (part-whole relationships), allowing for a rich understanding of word meanings and associations in natural language processing tasks. The structured data in WordNet can be used to perform tasks such as semantic similarity measurements, information retrieval, and word sense disambiguation.
