一种辅助用户搜索的聚类可视化搜索服务

A QoE-aware cluster visualization search service

针对用户搜索聚类的需求,以描述优先聚类算法为中心,利用提取高频短语获取候选聚类标签,并结合用户行为,提出一种基于搜索引擎的搜索结果可视化服务的实现机制.该机制包括聚类、可视化、用户反馈三个方面的算法,通过将用户的搜索结果动态转化及总结为相关聚类形态,基此进行可视化搜索呈现,引导用户快速获得搜索结果,并统计用户的使用习惯.实验表明:该机制可有效将用户搜索的结果进行汇聚,减少用户选择的选项,利用聚类等呈现手段辅助用户搜索.

A visualization service was provided to help user understand search result and guide them to obtain the results efficiently and correctly.Our works included result clustering,visualization and user feedback,which was transform search result into cluster and provided a visualization presentation. Results show that the service can assist user with search guideline and improve the search experience. Our major contribution includes assisting users to improve the search experience and implementing the system prototype.
