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

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

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

[2] This problem was solved using word alignment and POS tagging of parallel sentences [3] Derivation of complex predicates has also been dealt with linguistically and computationally CPs had been mined using computational methods and then, were categorized using statistical analysis [Sriram and Joshi, 2005]. Chakrabarti et al (2008) present a method for automatic extraction of CPs only from a corpus based on linguistic features
