Introduction
Wordnet is a lexical database of English, in which, nouns, verbs, adjectives and adverbs are grouped together into sets of synonyms (synsets). Synsets are linked by conceptual and lexical relations. There are a total of 117,659 synsets in wordnet 3.0, each expressing a distinct concept. Six types of relationship are found in Wordnet.
Hypernyms (Hyponyms)
Defines an IS-A relationship between nouns. For example:
- Honda IS-A Car (honda is a hyponym of car)
- Car IS-A Vehicle (car is a hyponym of vehicle)
The reverse relationship is expressed as:
- Car is a hypernym of Honda
- Vehicle is a hypernym of Car
Meronyms (Holonyms)
Defines a PART-OF (member) relationship between nouns. The opposite of a meronym (part) is a holonym (the name of the whole that contains the part). For example:
- tire PART-OF car (tire is a meronym of car)
- steering wheel PART-OF car (steering wheel is a meronym of car)
The reverse relationship is expressed as:
- car contains a tire (car is a holonym of tire)
- car contains a steering wheel (car is a holonym of steering wheel)
Troponyms
A verb expressing a specific way of doing something - a WAY-OF relationship. There is no known opposite to troponym. For example:
- stroll WAY-OF walk (stroll is a troponym of walk)
- amble WAY-OF walk (amble is a troponym of walk)
- walk WAY-OF move (walk is a troponym of move)
The reverse relationship is expressed as:
- move is accomplished by walking

Antonyms (synonyms)

Coordinate Terms
Nouns that share hypernyms with other nouns. Nouns and verbs that share the same hyponym. A car is a type of vehicle and a truck is a type of vehicle. Car and truck are therefore coordinate terms.
