摘要
由于排序策略不合理,图书馆OPAC系统中图书检索的排序效果较差,已经成为影响用户体验的重要瓶颈。为解决这一问题,在综合考虑可行性和对结果区分度的基础上,本文提出了一种融合权威性和时效性的排序优化模型。该模型主要由4个部分构成,分别是基础数据采集模块、多源数据融合模块、权威性和时效性权值离线计算模块、综合权值计算模块。
Because the ranking strategy is not reasonable, the poor ranking effect of library QPAC system has become an important bottleneck affecting user experience. To solve this problem, this paper proposes a ranking optimization model through fusing authority and timeliness on the basis of considering the feasibility and distinguished capacity. The mode~ mainly comprises the following 4 parts： basic data acquisition module, multi-source data fusion module, authority and timeliness offline calculation module and ranking weight integration module.
