Background At Shopee, we always strive to ensure the customer’s highest satisfaction. Whatever product is sold on Shopee, we ensure the best user experience starting from product searching to product delivery, including product packaging, and product quality. Once a product is delivered, we always encourage our customer to rate the product and write their overall experience on the product landing page. The rating and comments provided for a product by our buyers are most important to us. These product reviews help us to understand our customers needs and quickly adapt our services to provide a much better experience for our customers for the next order. The user's comments for a product ranges from aspects including delivery services, product packaging, product quality, product specifications, payment method, etc. Therefore it is important for us to build an accurate system to understand these reviews which has a great impact on overall Shopee’s user experience. This system is termed: "Shopee Product Review Sentiment Analyser". Note: This page is for participants from the student group! Task In this competition, a multiple product review sentiment classification model needs to be built. There are ~150k product reviews from different categories, including electronics, furniture, home & living products like air-conditioner and fashion products like T-shirts, rings, etc. For data security purposes, the review ids will be desensitized. The evaluation metrics is top-1 accuracy.
