Explicit measurement of experience, as mostly practiced, takes the form of satisfaction scores obtained by asking questions to users. Obtaining response from every user is not feasible, the responses are conditioned on the questions, and provide only a snapshot, while experience is a journey. Instead, we measure experience values from users’ click actions (events), thereby measuring for every user and for every event. The experience values are obtained without-asking-questions, by combining a recurrent neural network (RNN) with value elicitation from event-sequence. The platform environment is modelled using an RNN, recognizing that a user’s sequence of actions has a temporal dependence structure. We then elicit value of a user’s experience as a latent construct in this environment. We offer two methods: one based on rules crafted from consumer behavior theories, and another data-driven approach using fixed point iteration, similar to that used in model-based reinforcement learning. Evaluation and comparison with baseline show that experience values by themselves provide a good basis for predicting conversion behavior, without feature engineering.
