Thapar University WordNet Development Team

 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 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 būṭā ’plant’ } … (1)
 {
ਚਾਹ cāh ‘tea’ } … (2)
 Here {
ਪੌਦਾ paudā ’plant’ ,
ਬੂਟਾ būṭā ’plant’ } is hypernym of
{
ਚਾਹ cāh ‘tea’ } and {
ਚਾਹ cāh ‘tea’ } is hyponym of {
ਪੌਦਾ paudā ’plant’ ,
ਬੂਟਾ būṭā ’plant’ }

• 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 mōṭā ‘ fat’ ,
ਭਾਰੀ bhārī ‘fat’
,
ਸਥੂਲ sathūl ’fat’
,
ਥੂਲ thūl ‘fat’
,
ਨ ਿੱਗਰ niggar ’fat’ ,
ਵਜ ੀ vajnī ‘ fat’ }
…(1)
{
ਪਤਲਾ patlā ’thin’
,
ਦੁਬਲਾ dublā thin
,
ਕਮਜ਼ੋਰ kamzōr ’thin’
,
ਮਾੜਾ māṛā
’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 mōṭā ’ fat’ and
ਪਤਲਾ patlā ‘thin’ are in antonym relation but not the words
ਮੋਟਾ mōṭā ’ fat’ and
ਕਮਜ਼ੋਰ kamzōr ’thin’

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

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

 To cover all the antonyms created in Hindi WordNet.

tbl_anto_noun_action

Populate Records of Target Language Based on
Hindi Language Records

Contd ..
wn_synset_word wn_word

How to Save

 The Records are successfully saved in the database as shown wn_rel_antonymy wn_property_antonymy_ gradation

 The prerequisites for installation are following
-Java version 1.6
-MySql (Preferably Install Xampp Tool freely available on internet)
-Window 7

 Install JDK and MySql (preferably Xampp tool with integrated apache support)
 Install Sakal Bharti Font
 After successful installation of Xammp you will find Xampp folder in c drive.
 Open the data Folder using the following path
 C:\xampp\mysql\data

Contd..
 Copy iwn_web_unicode, wordnet_master and wordnet_target databases in the above folder
 Once you are ready with the databases you can open anto_tool.jar
with java and start working provided anto_tool.jar and lib folder should be placed in same location.
