  6. POS Category and WN • Verbs- • Gloss • Unique task • Following traditional grammar and Nyāya school • Takes care of semantics as well as syntax अपादान कर्ता कर्म

  7. Structural Difference between Hindi and Sanskrit राम खाना पका रहा है राम ने पत्र लिख डाला । पकाना Semantic Aspect Tense + Number Progressive Aspect + Gender+ Number लिखना Semantic Aspect Number+ Gender+ Aspect Tense, Aspect, Mood etc. expressed through a lexicalized units in Hindi

  8. Nature of verb in Sanskrit रामः ग्रामं गच्छति। गम् ति गमनम् वचनम् पुरुषः कालः Sanskrit does not use lexical item to denote tense, mood, aspect. कारकम् Tense, Number, Person and कारक Information fused in SUFFIX

  9. Issues related to link synsets of Verbs • Unable to link synsets expressing meaning such as • चुकना (synset id 10809) किसी कार्य का बाक़ी न रहना "क्या आप खाना खा चुके“ To eat Completion • संभावना होना, सकना (synset id 10149) कोई कार्य हो सकना आज बारिश होने की संभावना है। Expressed through a suffix. किं भवन्तःअभुक्षत। Expressed through a suffix. अद्य वर्षा भवेत्। संभावना होना

  10. POS of derived words • स्रष्टा- a creator • Two synsets in HWN in different categories

  11. स्रष्टा nominative singular of स्रष्टृ स्रष्टृ सृज् तृच् (Ashtadhyayi 3.1.133) to create कर्तृ of action • Derived Word • Can be said as an adjective • Lexicalized as a noun Creator

  12. वक्ता Occurrence in all genders Found in Vedic Literature as a noun in classical Sanskrit

  13.  (synset id 29330) • वक्ता, अलापी, अमूक, वादक, आख्यापक, आख्यायक  - • बोलने वाला   • "कभी-कभी वक्ता व्यक्ति को झेलना बड़ा मुश्किल हो जाता है“ • Adjective • Cannot be done in SWN

  14. Form vs Function • Conflict • lexical information is adjective • syntactic feature is like a noun • When a word is lexically an adjective but behaves like a noun on syntactic level then it is called as nominal. • The ability to take grammatical case marking. • Common Feature of Indian Languages • Adjectives are declined according to gender and number of a noun to which they modify in Sanskrit. • श्वेतो धावति। • Nominals should not be a part of WN which is semantic net.

  15. Nouns behave as an adjective on syntactic level is an adjectival. • Synsets of adjectivals difficult to cover in Sanskrit • Literal translation ‘मह्यं हिन्दीचित्रपटाः रोचन्ते।’ • हिंदी फिल्में– A compound in Sanskrit. • It is dissolved in Sanskrit as हिन्दी(भाषायाम्) चित्रपटः. • It is सप्तमी तत्पुरुष. • It is not an adjective in Sanskrit Compound.

  16. When a word is an adjective or a noun lexically but functions as an adverb syntactically then it is called as adverbial. • जवेन • जवात् • वेगेन • All these are nouns lexically. • When appear in instrumental or ablative case acts as an adverb • Should they form a part of a synset of an adverb?

  17. Conclusion • Impact of structural differences of Hindi and Sanskrit on development of SWN • Lexicalization of derived words needs to be studied • Historical development of a word should be considered while developing SWN • Nominals, Adjectivals and Adverbials will not be considered in SWN
