"To die for" misinterpreted #67

Closed fcpenha closed 5 years ago

fcpenha commented 5 years ago

I have found this basic common expression which is misinterpreted by Vader:

To die for.-------------- {'neg': 0.661, 'neu': 0.339, 'pos': 0.0, 'compound': -0.5994}

Could you consider adding a new rule for that?

AbtinZo commented 5 years ago

These cases should be added to special_case_idioms list with a positive value. You can customize that list and add to it manually.

fcpenha commented 5 years ago

@AbtinZohrabi I am not sure how to add these. You mean that I have to change the source code?

AbtinZo commented 5 years ago

@fcpenha Yes, There's a variable in this file vaderSentiment/vaderSentiment.py called SPECIAL_CASE_IDIOMS. you have to add to this list

ddugovic commented 5 years ago

For ease of understanding & future development might it make sense to store SENTIMENT_LADEN_IDIOMS and SPECIAL_CASE_IDIOMS with their scores in CSV files?

(Longer-term a database might work even better, so users can easily add/change scores with which they disagree.)

fcpenha commented 5 years ago

Sincerely, I like the idea of having this as an optional parameter, which in this case would be a python dictionary. Then, you don't need to worry about changing source code, and just do pip install and be happy.

AbtinZo commented 5 years ago

@ddugovic That would be a good option
