摘　　要：针对传统数字图书馆中文献检索质量不高的问题,提出了一种基于Wiki技术的文献检索模型。该检索模型是在传统文献检索系统的基础上集成了Wiki平台及技术,采用数据挖掘算法提取文献的检索参数和用户检索兴趣特征来提高文献检索的质量。实验证明,基于Wiki的文献检索系统其回调率和查准率在总体上都比传统的有了较大的改善和提高。Aiming at the problem of low retrieval quality in digital library, a novel literature retrieval model based on Wiki technology was studied.This retrieval model integrated Wiki technology with the traditional literature retrieval system, and adopted data mining algorithms to extract literature retrieval parameters and user interest characteristics from retrieval history to improve the quality of literature retrieval.The results showed that the recall and precision of the new retrieval model based on Wiki technology were better than those of the traditional retrieval system.
