摘　　要：如何为用户精准提供高质量信息是信息检索系统有效提升用户体验的关键问题所在。在对国内外相关技术研究进展基础之上,从引入信息资源与用户需求之间最佳匹配的动态评估机制角度,提出了一种面向用户体验增强的信息检索动态评估模型,对模型中的信息质量评估方法、用户期望评估方法、情境动态评估方法和用户体验评估方法等进行详细设计,并对模型中各因素权重进行最优化搜索求解。仿真实验结果表明,构建的动态评估模型具有较好的“鲁棒”特性,对不满足用户需求的信息过滤效果明显,将用户所需的高质量信息返回给用户,明显增强了用户对信息检索的应用体验。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.
