摘　　要：针对当前不同英语学习者水平的差异,提出一种基于英语水平的检索系统。为实现该系统,首先对该系统进行了简单的目标描述,为后续的设计提供依据;其次构建索引文件和快速查询算法。另外,为解决当前检索中文本内容不满足不同英语学习者的层次,引入时间窗口概念和文本权重概念,以查询项和点击记录作为分析依据,同时引入线性融合思想,构建综合考察查询项和点击记录的用户水平判断模型。最后给出检索的结果。A retrieval system based on English proficiency is proposed for different English learners.In order to realize the system,firstly,a simple description of the system is given,which provides a basis for subsequent design.Secondly,an index file and a fast query algorithm are constructed.In addition,in order to solve the problem that the current retrieval of text content does not satisfy the different levels of English learners,the concept of time window and text weight are introduced.Based on the analysis of query items and click records,a user level judgment model is constructed by introducing the idea of linear fusion.Finally,the retrieval results are given.
