Tasks Your task is sentiment classification. We create class labels for reviews as follows: Rating = 1 or 2: negative, rating = 3: neutral, rating = 4 or 5: positive. Build a sentiment classifier using any of the methods implemented in WEKA. Submit a hard copy report addressing the following issues: 1) Describe the features that you used for your classifier as well as why and how you selected them. 2) Discuss your choice of a classification method. You may have to experiment with several methods and may report some of the preliminary results as arguments. 3) Give the classification accuracy, the precision and recall and the F-measure (for the positive class and for the negative class) of your sentiment classifier. You need to perform 5-fold cross-validation to compute your performance measures. 4) Design and implement a method that explains the results of your sentiment classifier. Discuss your design and provide the actual explanations produced for the classification of the first reviews of each product category. Marking scheme Each of the four issues listed above is worth 25% of the course project marks.
