Semantix

The Semantix crawler - in progress.

Implements a Naive Bayes classifier using the NLTK library.

Notes

We activate a virtual environment to ensure our project runs on the enclosed Python version and is not affected by the other Python versions installed on the machine. Flask is also installed into the virtual environment, and not globally on our machine.

You can also run python app/main.py to check out the main algorithms without starting flask.

OCR Recognition

OCR recognition is done using the Tesseract library.

1. brew install tesseract

Usage:
tesseract [image_name] [output_file]
