Slide 2

Introduction to WordNet A WordNet is a large lexical database of a language. Nouns, verbs, adjectives and adverbs are grouped into sets of cognitive synonyms (synsets), each expressing a distinct concept. Each synset in WordNet is related to other synsets by well known two types of relations. -Semantic Relation -Lexical Relation

Slide 3

Semantic Relation Semantic relations are the relations between two whole synsets. Same for all the languages. For example Hpernymy/hyponymy relation, Consider two synsets given in (1) and (2). { paud plant, b plant} (1) { ch tea} (2) Here { paud plant, b plant } is hypernym of { ch tea} and { ch tea} is hyponym of { paud plant, b plant }

Slide 4

Lexical Relation Lexical relations are language dependent. Lexical relations are the relations between members of two different synsets. For example consider two synsets given in (1) and (2) { m fat, bhr fat, sathl fat, thl fat, niggar fat, vajn fat} (1) { patl thin, dubl thin, kamzr thin, m thin}...(2) Here, synsets (1) and (2) are opposites but they does not share antonym relation. Antonym relation exist between two words not between two synsets. Here the words m fat and patl thin are in antonym relation but not the words m fat and kamzr thin
