文中利用知识发现领域中的信息扩张机制,研究提出一种对意外规则取舍和理解的新处理方法——三度(规则支持度、可信度、充分性因子)变化趋势分析,再结合规则前件、后件的支持度的历史变化规律的呈现和分析,得到可保留的规则。并帮助用户充分理解规则,合理运用规则。这项研究对知识发现的后处理与可实现性、实用性起着重要的作用。
With information increasing mechanism in the domain of knowledge discovery, a new processing method is proposed, that is the changes in trends analysition of three- matrics(rule's support degree; credibility and sufficiency factors). By analysing the history variation of the support degree of rule's antecedents and consequents,the rules are retained. Then help user to understand and reasonable use ruls. The research will play an important roles in post-preeessing,realizability and practicality of knowledge discovery.
