Machine translation for multilingual sentiment analysis

I am trying to do sentiment analysis for non english languages like japenese, chinese, german etc. I want to know if any Machine translator av开发者_运维问答ailable for translating documents in these languages to english. I am working on JAVA so I should be able to call the API or tool. I have used google translator API so please suggest anything apart from it.

Sentiment analysis is highly dependent on both the culture and the domain of practice (see http://en.wikipedia.org/wiki/Sentiment_analysis ). We are working in the area of SA for scientific texts and this is undoubtedly a research area. So I don't think you will find anything off-the-shelf either for the human language or for the SA.

There are a plenty of different Machine Translation APIs: Google, Microsoft, Yandex, IBM, PROMT, Systran, Baidu etc.

I may refer you to our recent evaluation study (November 2017): https://www.slideshare.net/KonstantinSavenkov/state-of-the-machine-translation-by-intento-november-2017-81574321

However, it's not clear how MT quality scores are correlated with good sentiment analysis on the results. That's something we are going to explore soon.
