Antonym Creation Tool Presented By Thapar University WordNet Development Team

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

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). { ਪੌਦਾ paudā ’plant’, ਬੂਟਾ bū ṭ ā ’plant’} … (1) { ਚਾਹ cāh ‘tea’} … (2) Here { ਪੌਦਾ paudā ’plant’, ਬੂਟਾ bū ṭ ā ’plant’ } is hypernym of { ਚਾਹ cāh ‘tea’} and { ਚਾਹ cāh ‘tea’} is hyponym of { ਪੌਦਾ paudā ’plant’, ਬੂਟਾ bū ṭ ā ’plant’ }

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) { ਮੋਟਾ mō ṭ ā ‘fat’, ਭਾਰੀ bhārī ‘fat’, ਸਥੂਲ sathūl ’fat’, ਥੂਲ thūl ‘fat’, ਨਿੱਗਰ niggar ’fat’, ਵਜਨੀ vajnī ‘fat’} …(1) { ਪਤਲਾ patlā ’thin’, ਦੁਬਲਾ dublā thin, ਕਮਜ਼ੋਰ kamzōr ’thin’, ਮਾੜਾ mā ṛ ā ’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 ਮੋਟਾ mō ṭ ā ’fat’ and ਪਤਲਾ patlā ‘thin’ are in antonym relation but not the words ਮੋਟਾ mō ṭ ā ’fat’ and ਕਮਜ਼ੋਰ kamzōr ’thin’

Antonym Creation Tool Helps to create the antonyms for any language. Eliminates the manual typing effort. Tool provides a user friendly interface for creation of antonyms.

Idea Behind Development of Antonym Creation Tool Antonyms for Hindi Language has been already created by IIT, Bombay. All Indian Language WordNets are being created using expansion approach from Hindi WordNet. So, antonyms created in Hindi Language will be covered in all other languages.

Hindi WordNet Antonyms Hindi WordNet antonyms are classified into four major categories - Noun - Verb -Adjective - Adverb These are further classified into 12 subtypes - Action - Personality - Amount- Place - Color- Quality - Direction- Size - Gender- State - Manner- Time

Challenges for Creation of Antonym Creation Tool Since the WordNet database has been modified by Goa University, So it is important to design a tool which can port the data into new database from old database. wn_rel_antonymy

Development Approach To cover all the antonyms created in Hindi WordNet.
