## Scenario

PyCharm with Python 3.7 was used so that the Spacy library could work properly.


We wrote 2 methods to convert the sentences: one that writes the dataset with children/head (1h) and the other without (20 minutes).


In agreement with Professor Luc Lamontagne, to make task 3 go faster, we wrote the converted sentences of the method using the dependency tree of the negation_conversion.py file in text files.


These files were produced with the write_negated method found in the sentiment_analysis.py file. They are stored in the data folder.


Also, it is necessary to download the NLTK corpus, Sentiwordnet so that the sentiment_analyse.py file can work.








## Steps

( See file *negation_conversion.py* )

- Step 1: Find the scope of the sentence

- Step 2: Capture the negative scope

- Step 3: Conversion and reconstruction of the sentence
