C++ Sentiment Analysis Library [closed]

Question

I'm looking for a C++ sentiment analysis library that I could use in my own application. Something that would take a text written by a human as an argument and return information on its mood (positive, negative, neutral, angry, happy, ...). Any ideas?

A few remarks:

• I'm not looking for a library with "just" NLP tools (as text tokenization, PoS tagging etc.), but really something that does sentiment analysis / opinion mining / mood analysis. Of course an NLP library with sentiment analysis tool is great.
• Something very simple would be ok (e.g. just returning +1/-1/0)
• I don't care which underlying technique it may use (dictionaries, bayesian stuffs, SVMs, rule-based...)
• C++ only!

I know it probably does not exist just like that, but hey.

Answer 1

I'd suggest writing your own. You can capture 80% of mood correctly with a simple filter for positive and negative sentiment words, and you can scale your sign based on some common modal words and punctuation. If you want to squeeze juice out of that remaining 20% of ambiguity and you don't want to train your own SVM or whatever, I'd suggest finding papers at op.to/goog/scholar+ some of those papers will have authors who have written C++ libs and talking about where you can find / download them.
