Understanding how customers feel about your level of service and product has caused a revolution in several approaches, including customer satisfaction (CSAT), Net Promoter Score (NPS) surveys, etc. An overarching question that arises is how you can predict and scale customer happiness if customers don’t respond to the survey. The question is of pivotal importance to the LinkedIn global customer operation team in elevating members’ and customers’ experience to discover the full value of LinkedIn. To tackle this issue, the data science team at LinkedIn developed an end-to-end data product.

Kelly Wan, Jason Wang, and Lili Zhou walk you through the interesting problems the LinkedIn data science team faces and the innovative approaches they’ve adopted and milestones they reached. In particular, they focus on the problem of understanding, measuring, and predicting customer happiness toward customer support service and products—a problem that’s received a lot of attention in the last couple years. They describe the data they leverage: structured data, that is, operational efficiency key metrics, and unstructured data such as customer email. You’ll learn how the team synthesizes multidimensional signals and develops a comprehensive way to measure customer experience. This includes feature engineering and feature selection and how to predict customer sentiment through scalable text mining techniques on customer verbatim by leveraging neural net-based methodologies. They detail a few methods—FastText supervised model, attention- and transformer-based architecture, recurrent neural network (RNN) and convolutional neural network (CNN) with fine tuning, etc. You’ll dive into how the team designed and developed an innovative data product to provide actionable insights and strategies, which enlightens and recommends LinkedIn to perfect customer experience and further boost its product engagement and revenues.
