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。
Due to the unreasonable sorting strategy, the book retrieval in the OPAC system in the library has a poor sorting effect and has become an important bottleneck affecting the user experience. In order to solve this problem, based on the consideration of feasibility and differentiation of results, this paper presents a sort of optimization model that integrates authoritativeness and timeliness. The model is mainly composed of 4 parts, which are the basic data acquisition module, multi-source data fusion module, the authoritative and time-dependent weight offline calculation module and the integrated weight calculation module.
