Relevance models in relevance research is the main research issue in information retrieval and information science. Relevance research of information retrieval can be divided into the system-oriented school and the user-oriented schoo1.The evaluation of relevance is closely related to user's experiences, cognitive status and thinking, and includes the interaction of several level. On this basis, a four-dimension model (information resource, representation of user problem time and components) and an interactive model are critically illuminated. A better understanding of the cognitive model, the episode model and the stratified model is of great importance to the interactive model.
