刑侦数据仓库模型设计与数据挖掘技术应用

Model Design and Application of Data Mining Based on the Data Warehouse of Criminal Investigation

针对当前刑侦海量档案数据信息,首先在分析其数据跨平台、复杂化和多样性特点的基础上,设计了刑侦数据仓库的概念模型、逻辑模型和物理模型;接着针对刑侦数据仓库及数据挖掘技术,对已有的刑侦档案数据进行信息整合和数据挖掘,获取大量的有用知识,这些知识在促进刑侦研究工作的同时,对一线的实际刑侦工作具有很大的参考价值;最后,文章给出了面向刑侦档案数据信息的仓库模型,针对其数据挖掘系统框架提出了相应的数据挖掘方法,为进一步的刑侦数据信息联机分析处理和有用信息挖掘以及为公安安全防范决策服务。

Firstly the conceptual model,logic model and physical model of the data warehouse of criminal investigation are analysis and designed by characteristic of the data of criminal investigation;then according to the data warehouse and data mining technology,information integration and data mining on archives of criminal investigation which have been done,and plenty of useful knowledge is obtained,and which might have great value for criminal investigation study and on site work. Last system framework and data mining method based on the data warehouse of criminal investigation have been gave,which beneifcial to online analytical processing,useful information mining and public security making.
