How do you deal with the English text having Hindi words in between?  Normalize the word tokens, Transliterate the words in Hindi language script (Devanagari) and look up the words in Hindi dictionary for its existence. Check for spelling variations. If found tag them as such.  Lookup all the words in English dictionary and tag them as such. If there is tie with the other language then use word frequency probability to break the tie.  Perform the POS Tag analysis to get the words tagged as either noun, adjective, adverb and verb.  Loop up the sentiment scores from sentiwordnet of each languages (Hindi/English), for each token based on their language tags.  Use wordnet to get the identifier and use senti-wordnet to get the sentiment associated with those words along with the corresponding tags we found in the POS tag analysis  Convert the words in to features:  Remove stop words  Remove the words senti-scores that are not important such as everything except adjective and adverbs, since they are the most important ones where sentiments are concerned  Create an ngram feature to hook words with its context  Feed it to a classifier for training and then test on the subject to calculate accuracy
