Movie Review Classifier

The purpose of this package is to perform semantic analysis on movie reviews using machine learning. It makes use of the imdb review dataset and is based on some excellent tutorials from Sebastian Raschka in Python Machine Learning.

Note model was originally persisted using scikit-learn version 0.18.1 so if your version is different you may need to re-persist the model by running

path/to/python path/to/MovieReviewClassifier/MovieReviewClassifier.py

To run this you will need to install python and many scientific packages the easiest way to get all that is by installing Anaconda

To run semantic predictions just run

path/to/python path/to/MovieReviewClassifier/MovieReviewPredict.py "Movie Review text goes here"

Output follows the format Prediction,Probability for example positive,93.5 if the algorithm is 93.5% sure it is a positive review

With settings as is it is around 90% accurate feel free to further tune it on your own.
