General Readme on Projects

Web commerce sites get a substantial amount of feedback from reviews users post on various websites. It is not practical to go through all this information by hand to determine whether a user liked a particular product or not.

For our project we are going to use a dataset of Amazon Musical Instrument Reviews. The main reason I selected this dataset is that it is significantly smaller than the Amazon review datasets for movies, music, and books. This dataset has a bit over 221,000 reviews. The columns in the dataset are

name	description
verified	whether the reviewer bought the product from Amazon or not
reviewTime	time of the review
reviewerID	ID of the reviewer, e.g. A2SUAM1J3GNN3B
asin	ID of the product
reviewerName	name of the reviewer
reviewText	the text of the body of the review
summary	the test of the heading of the review
unixReviewTime	time of the review (Unix time)
vote	the number of times other reviewers thought the review helpful
style	the attributes that vary -- for a example for a shirt it might be medium blue
image	the associated image for the item.
rating	what we are trying to learn to predict a positive, neutral, or negative review.

You are to develop a classifier that predicts the rating.

The file with the training data is at http://34.82.108.37/amazonReviewsTrain.csv.zip

Once you are done training and tuning your classify you should run it on the test data.

The file with the test data is http://34.82.108.37/amazonReviewsTest.csv

Your predictions for the test set should be in a text file named amazonReviewsPredictions.txt that is placed in the same github directory as your Jupyter notebook file containing your code and comments.

The format of this predictions file should be

neutral positive positive positive neutral neutral positive positive positive positive ...

To test the format of your output file you can use the following function:

def test(): i = 0 answers = ['negative', 'neutral', 'positive'] with open('amazonReviewsPredictions.txt', 'r') as outfile: lines = outfile.readlines() for line in lines: if line.strip() not in answers: return("invalid entry line %i" % (i)) i += 1 if i != 10000: return ("incorrect number of lines") else: return ("file looks ok") test()
