With the advent of the information age, new services of high diversity emerge continuously. The demand of people for services is growing higher. The service providers should improve the Quality of Experience of the users, in order to keep users for their services. Therefore Quality of Experience has become one of the important topic in the academic world as well as an ultimate business metrics in the industry. In this paper, we provide a complete overview on evaluation models and methods of Quality of Experience. We summarize the influence factors, qualification methods and three evaluation methodologies, and focus on the concrete models and evaluation methods based on several disciplines. Then we provide a model of Quality of Experience for video streaming based on hidden Markov model, propose an evaluation method of QoE based on stochastic model and indicate the directions of future research on Quality of Experience.
