Estonian Wordnet can be browsed in Teksaurus or WordTies.
The atom of a wordnet-type thesaurus is a synonym set (also called a synset), which is a set containing all the synonymous words or multi-word units that express the same concept. All words in a synset belong into the same part of speech. In the simplest case, such set contains only one word, i.e. that word does not have any synonyms (the corresponding concept can be expressed by only one word).
The synsets are connected by links which correspond to semantic or lexical relations between concepts. The most important relations are hyponymy and hypernymy, but also meronymy, holonymy, antonymy, cause, role, derivational relations are marked.
Estonian Wordnet is based on the wordnet theory and we have closely followed the principles adopted in the Princeton WordNet and EuroWordNet projects.
EstWN currently (October 2021) contains about 91,700 concepts (about 148,000 words) which is held in place by 306,000 relations. The work is still in progress.
EstWN includes nouns, verbs, adjectives and adverbs, as well as a set of multiword units. All concepts are also linked via InterLingualIndex (ILI) with English (Princeton WordNet).
Experiments done in Word Sense Disambiguation of real texts have shown that the senses of the main vocabulary of Estonian have been included in EstWN.
