>>> import pysentiment as ps
>>> hiv4 = ps.HIV4()
>>> tokens = hiv4.tokenize(text)  # text can be tokenized by other ways
                                  # however, dict in HIV4 is preprocessed
                                  # by the default tokenizer in the library
>>> score = hiv4.get_score(tokens)

HIV4 is a subclass for pysentiment.base.BaseDict. BaseDict can be inherited by implmenting init_dict to initialize _posset and _negset for the dictionary to calculate ‘positive’ or ‘negative’ scores for terms.


Bug-fixes / features are always welcome.
