Research on an information retrieval evaluation model for user experience enhancement

Abstract： How to accurately provide high-quality information to users is the critical issue for information retrieval system, which are intended to effectively improve user application experience. Based on the progress of related research at home and abroad, a dynamic evaluation model towards information retrieval system is proposed from dynamic evaluation mechanism of optimal matching between information resource and user requirement. As the main function modules in the dynamic evaluation model, information quality evaluation method, user expectation evaluation method, situation dynamic evaluation method and user experience assessment method are designed in details, and how to determine the weight of each functional module is optimized by genetic algorithm. The simulation results show that the dynamic evaluation model has good “robustness”, which can not only filter the information that does not meet the needs of users, but also effectively present high-quality information to users who need it, and it will significantly improve user application experience of information retrieval.
