Simple negation detector

This repository contains scripts to detect negations in Dutch and English.

Requirements & setup

This script has been tested with Python 3.5, but it should work with Python 2.7 as well. Installation is slightly different, as you need to make sure you have the right version of treetagger-python.

1. Install Treetagger.
2. Install the NLTK. Be sure to also download the pre-trained tokenizers. import nltk, followed by nltk.download('all') should work, but you can also manually select what you want to install.
3. Install treetagger-python.

Using the negation detector

from negation_detector import NegationDetector
nd = NegationDetector('english') # or 'spanish' or 'dutch'.

# See whether the word is a negation, and if so: what kind.
neg, kind = nd.negation_status('no')

# Analyze a sentence.
analyzed_sentence = nd.check_sentence("I don't like spam.")

# Analyze a text
# Doesn't work well with newlines, so split the text into paragraphs using text.split('\n')
# and check paragraph by paragraph.
analyzed_text = nd.check_text("I don't like spam. It is not something I like.")
