IntroductionIntroduction
1. Importance of Verbs
• Verbs are the most important categories in parts of speech
• Sentence without a verb is unthinkable
2. Inspired by Beth Levin’s English Verb classes and Alternations
3. Syntactic Alternations
• Refer to the argument structure of the verbs
Page 4

MotivationMotivation
1. Absence of deep hierarchical semantic tree.
2. Hypothesis of Beth Levin : Semantic nature of verbs are largely predictable by their syntactic structure.
3. Absence of any such work in Indian languages.

ConclusionConclusion
1. Present work deals only with the syntactic pattern and does not handle the semantic part.
2. The work deals only with the simple verbs.
3. It gives detail phonological, morphological and syntactic information of Verbs in Hindi.
4. Inclusion of such information crucial to Machine translation.

Future WorkFuture Work
1. Semantic categorization according to syntactic pattern.
2. Extend the work to other Indian languages.
