Bugs in calculating sentiment

[pienio7]

I found bugs in calculating sentiment:

• Sentiment for the phrase "definitely happy" is the same as sentiment for word "happy" (polarity=0.8, subjectivity=1.0) - but "definitely" has intensity="2.0", so polarity of "definitely happy" should by 1.0.
• Sentiment for "very no happy" is (polarity=-0.5, subjectivity=1.0) and for "very not happy" is (polarity=-0.1, subjectivity=0.65) - but it should be the same.
