In this project I gathered several pieces of structured information on a collection of mobile phones from the Amazon website. Among theses pieces there is one important source of information on the phones which is the textual consumer ratings or text review.
In fact, the text review provides extremely useful feedback for producers, the information in textual reviews can be a lot more detailed that's why I apply the text mining by using a dictionary-based approach to classify the reviews as positive, negative etc...
