Abstract

Rule design is very important for active database system implementation. But, it is also very difficult for us because of lacking methodology and support. In the paper, active rule design is regarded as a whole process and identified to three steps: rule extraction, rule analysis, and rule update. Data mining technique is originally introduced into rule design by us to cope with the problems arisen in active semantic extraction, termination analysis of rules set, and rules update. Rule mining methods are adopted to extract active semantics, and the discovered rules are used to assist active rule specification. Data mining technique is integrated with the triggering graph to improve the accuracy of termination analysis. Finally, data mining technique is used to identify new semantics and determine which rules should be updated.
数据挖掘在主动数据库系统规则设计中的应用
规则设计对于动态数据库系统的实现是非常重要的。但是,由于缺乏方法和支持,这对我们来说也是非常困难的。本文将主动规则设计视为一个完整的过程,将其划分为三个步骤:规则提取、规则分析和规则更新。数据挖掘技术最初是为了解决主动语义提取、规则集终止分析、规则更新等问题而引入规则设计的。采用规则挖掘方法提取活动语义,并利用发现的规则辅助活动规则规范。将数据挖掘技术与触发图相结合,提高了终止分析的准确性。最后,利用数据挖掘技术识别新的语义,确定哪些规则需要更新。
