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:

  • 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)

  • 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)

  • walk WAY-OF move (walk is a troponym of move)
