序列模式挖掘技术在数字图书馆中的应用

The Application of Sequential Pattern Mining Technique in Digital Library

通过研究序列模式挖掘算法,将序列模式挖掘技术与数字图书馆有机结合。可以从3个方面入手,一是对Web环境下的读者访问日志序列进行挖掘可以为每个读者提供个性化服务;二是依据挖掘得到的被拒集及频繁借阅集可阶段性补充图书馆特色资源;三是利用挖掘技术分析资源利用情况可指引图书馆电子文献资源的采购,实现图书馆智能化服务。

Through researching on sequential pattern mining algorithms, this paper combined sequential pattern mining technology with digital library, and implemented it from three aspects. Firstly, mining readers＇ access log sequence under web environment could provide personalized service for every reader. Secondly, on the basic of the rejection sets and frequent borrowing sets mined, libraries could periodically supplement characteristic resource. Thirdly, using mining technology and analyzing resource utilization could direct the procurement of library electronic resource and realize intelligent service.
