WordNet – Lexical Database of English
Word Net is a useful tool because of many reasons:
- Nouns, verbs, adjectives and adverbs are grouped into sets of cognitive synonyms (synsets)
- Each synsets expressing a distinct concept.
- Synsets are interlinked by means of conceptual-semantic and lexical relations.
The whole network of meaningfully related vocabulary items and concepts can be navigated through a browser
You can also download a free version of the tool.
Note that the database is still under construction. But it’s a project worth being encouraged because of its importance for computational linguistics and natural language processing.
