Can someone please elaborate this result?

It can be tested here: http://nlp.stanford.edu:8080/parser/index.jsp

I want to get sentiment result of the sentence. Whether +ve or -ve? with its score value.

Solution

  • The Stanford NLP documentation refers to the Penn treebank documentation for the precise definitions.

    However, if PRP == personal pronoun and VBP == present-tense verb were hard to guess, perhaps you should start with some NLP fundamentals before attempting this.

    A part-of-speech tagger as such does not perform any sort of sentiment analysis.
