2. Outline • Introduction • Issue in linkage • Linkage Problem due to POS Mismatch • Linkage Problem due to Hindi Construction like Causative Verb • Linkage Problem due to Idiomaticity • Linkage Problem due to Culture Specific • Linkage Problem due to MW

3. Introduction • Linkage between HWN 1.2 and EWN 2.1 • Two types of linkage:- i) Direct linkage ii) Hypernymy linkage • Direct Linkage- The synsetshaving exact equivalents in English WordNet are to be linked through direct linkage. For example, आम (aama), आम वृक्ष (aamavriksha) is to be linked to the English synset mango, mango tree - (large evergreen tropical tree cultivated for its large oval fruit).

4. HypernymyLinkage • The synsets which cannot be linked directly to English concepts are to be linked through hypernymy linkage. For example, the Hindi synsets of चाचा (chaachaa, paternal uncle) and मामा (maamaa,maternal uncle) would be linked to the English synset of uncle through hypernymy linkage.

5. Issues in Linkage • Synsets cannot be linked due to unavailability of corresponding English synsets in EWN • Nouns For example:- आल आउट, ऑल आउट, आल आऊट, ऑल आऊट - एक पक्ष के सभी खिलाड़ियों के आउट होने की क्रिया"आज भारतीय क्रिकेट टीम 195 पर ही आल आउट हो गई” Aalaaauta-EkapakshakesaviikhiilaaDiyonkeaauta hone kiikriyaa “aajabhaaratiiyakriketatiima 195 parahiiaalaaauta ho gaii” All out- Act of all players of a team being out “today Indian cricket team was all out at 195 ”

6. Issues in Verb Linkage • Verbs- Like the following verb are unlinkable. For example:- स्तब्ध होना, निश्चेष्ट होना, जड़ होना, बधिर होना, बहरा होना, बहिरा होना - संवेदनाशून्य होना "सब कुछ समाप्त हो चुका है यह खबर सुनकर वह पूर्ण रूप से स्तब्ध हो गया” stabdhahonaa, nishchestahonaa, jaDahonaa, badhirahonaa, baharaahonaa, bahiraahonaa _sanvedanaashoonyahonaa “sabakuchhasamaapta ho chukaahaiyahakhabarasunakaravahapoorNaroopa se stabdha ho gayaa” to be shocked – be numbed “ after listening the news that every thing is finished, he was completely shocked ”

7. Issues in Adjective Linkage • Adjective:- hypernymy linkage is not possible. For example:- एकल- जिसमें एक पक्ष में केवल एक खिलाड़ी हो "नडाल ने एकल स्पर्धा के फाइनल में प्रवेश किया” ekala- jisamenekapaksha men kevalaekakhilaaDiiho“nadaala ne ekalaspardhakephainala men praveshkiya” Single-That which has one player in one team/side “Nadal entered in final of single competition”

8. Issues in Adverb Linkage • Adverb:- This also cannot be linked with hypernymy. For Example:- के कारण, की वजह से, के चलते, के मारे - किसी कारण से"तेज़ बारिश के कारण मैं भीग गया“ KekaaraNa, kiivajaha se, kechalate, kemaare- kisiikaaraNa se “tejabaarishakekaaraNa main bhiigagayaa” Due to, because of, on account of (it is a conjuction or preposition in English so cannot be linked) “due to heavy rain I got wet”

9.

13. Linking Problem due to Hindi construction like causative • बनवाना  - दाढ़ी या बाल कटवाना या पूरी तरह से निकलवा देना"मैंने नाई से दाढ़ी बनवाई“Verb banavaanaa- daadhiiyaabaalakatavaanaayaapooriitaraha se nikalavaadenaa “mainnenaaii se daadhiibanavaaii” To get a trim or shave:- To get the hair or beard cut or get it shaved completely “I got my beard shaved by the barber” • तुड़वाना, तोड़वाना, तुड़ाना, टोरवाना, तोरवाना - कोई वस्तु आदि को या उसका भाग तोड़ने का काम दूसरे से कराना "माँ राधे से लकड़ियाँ तुड़वा रही है” Verb tuDavaanaa, toDavaanaa, tuDaanaa,toravaanaa –koiivastuaadiikoyaausakaabhaagatorDanekaakaamadoosare se karavaanaa “maanraadhe se lakaDiyaantuDavaarahiihai” Cause to break:-To get some object or a part of it broken by some one. “mother is getting woods broken by radhe”

The motion is passed or rejected by means of a new parliamentary vote (a vote of non-confidence).

18. Computational issues

19. Migrating from PWN 2.1 to PWN 3.0 • Issue: • PWN 3.0 has a larger pool of concepts than PWN 2.1 • Hence in several cases linking to PWN 3.0 will be easier • Proposed Solution: • Migration of linked synsets from PWN 2.1 to PWN 3.0 • Upgrading the PWN database in Hindi-English WordNet Linking tool from 2.1 to 3.0

20. Problems due to Pos Mismatch and some Idiomatic Cases • Issue: • POS Mismatch – Corresponding sense in English may have a different POS • Idioms – In particular cases the corresponding sense in English may be available but may have a different POS • Proposed Solution: • If linking is allowed across POSs, then the tool can be accordingly adjusted to link across POSs
