These reviews often have important business insights that can be leveraged to perform actions that can improve profits. In this project we analyze ~400,000 mobile phone reviews from Amazon.com aiming to find trends and patterns to determine which product characteristics are mentioned most by customers and with what sentiment. 6 | 7 | Our task is performed in six steps: 8 | 9 | (1) pre-processing to prepare the data for analysis including tokenization and part-of-speech tagging 10 | 11 | (2) product names standardization 12 | 13 | (3) characteristics extraction 14 | 15 | (4) reviews filtering to remove reviews considered as outliers, unbalanced or meaningless 16 | 17 | (5) sentiment extraction for each product-characteristic 18 | 19 | (6) performance analysis to determine the accuracy of the model where we evaluate characteristic extraction separately from sentiment scores 20 | 21 | The dataset can be found in Kaggle: 22 | - https://www.kaggle.com/PromptCloudHQ/amazon-reviews-unlocked-mobile-phones/downloads/Amazon_Unlocked_Mobile.csv 23 | 24 | ## Methodology 25 | 26 | A flowchart of the project, including the approach, performance and final business analysis is presented below: 27 | 28 | 29 | -------------------------------------------------------------------------------- /data/annotated_test_set.txt: -------------------------------------------------------------------------------- 1 | 757, Lenovo A850, {battery:-1};
