1 GUIDE : Prof. Amitabha Mukerjee By : Amit Kumar (10074) Ankit Modi (10104)

2 A Complex Predicate (CP) is a multi-word compound that functions as a single verb Ex : उसन क त ब व पस र द य म झ बच च म त -पपत ओ स थ म रन भ अच छ लगत ह ज क अक सर सल ह ल न आत ह - यह ज न र ख श ह त ह क आप क स म र स त ह

3 CP = Word + Light Verb Ex : उसन क त ब व पस र द य र द य (CP) = र (W) + द य (LV) A Light Verb is a verb that has little semantic content of its own and it therefore forms a predicate with some additional expression, which is usually a noun. Ex : न, ल न, प न, उठ न

4 Given a parallel English Hindi corpora, we have to detect complex predicates (CPs) Using the fact that a CP is a multi word expression with its meaning being distinct from the light verb (LV).

5 CPs improve expressiveness of a language and Hindi is abundant in it

6 CPs improve expressiveness of a language and Hindi is abundant in it Detection of CPs is a tough task

7 CPs improve expressiveness of a language and Hindi is abundant in it Detection of CPs is a tough task Their detection provides important resource for tasks such as Wordnet construction, Linguistic analysis etc

12 Framework Aligned English- Hindi corpus Search for Hindi LV & its morphological forms Search for equivalent English meaning of LVs Collect the Hindi word (W) if it is not a stop word or else keep scanning Scan left of those LVs whose English meaning is not found I also enjoy working with the children's parents who often come to me for advice - it's good to know you can help म झ बच च म त -पपत ओ स थ क म रन भ अच छ लगत ह ज क अक सर सल ह ल न आत ह - यह ज न र ख श ह त ह क आप क स मदद र स त ह

13 Framework Aligned English- Hindi corpus Search for Hindi LV & its morphological forms Search for equivalent English meaning of LVs CP = W+LV unless W is an exit word Collect the Hindi word (W) if it is not a stop word or else keep scanning Scan left of those LVs whose English meaning is not found I also enjoy working with the children's parents who often come to me for advice - it's good to know you can help म झ बच च म त -पपत ओ स थ क म करन भ अच छ लगत ह ज क अक सर सल ह ल न आत ह - यह ज न र ख श ह त ह क आप क स मदद कर स त ह

14 As of now, we have extracted 10,000 CPs But we need to add more morphological forms in Hindi LV list.
