Among the popular Internet models, E-commerce platforms such as Amazon.com and Taobao.com have evolved into the most comprehensive and prosperous ecosystems. They not only deeply involve other traditional businesses such as payment and logistics, but also largely transform every aspect of retailing. Taking the customer service on Taobao platform as an example, third-party retailers are always online to answer any question at any stage of pre-sale, sale and after-sale, through an instant messenger within the platform. The topics of these customer service dialogues involve various aspects of online shopping, such as product information, return or exchange, logistics, etc. Based on a previous survey, over 77% of buyers on Taobao communicated with sellers before placing an order. Therefore, such service dialogue data contains very important clues for sellers to improve their service.
