Along with time fast vicissitude, the former information is not easy the seal society which circulates, gradually transforms the open society which the information explodes. All information could get by information science and technology. For example, the television, broadcast or Internet and so on.But so huge information quantity has surpassed the limit which the people brains can process.Therefore, how to avoid "GIGO", needs to depend on the information science and technology to solve. Data Mining is a very good method. The goal is extracts particular and useful information or knowledge of users from huge data. And data mining may divide into very variously, this paper is does take "Sequential Pattern" as the research subject.

随著时代的快速变迁，以往资讯不易流通的封闭性社会，逐渐转变成资讯爆炸的开放性社会，所有的资讯，皆可由电视、广播或是网际网路等资讯科技来获得，但如此庞大的资讯数量，已超出了人们头脑所能处理的极限，所以如何避免「GIGO」，需要靠资讯科技的技术来解决，「资料探勘」即是其中一个，目的就是要从巨量的资料量中，粹取出使用者所特定、渴望的资讯或知识，而资料探勘可分为很多方面，本篇论文是以「序列型样」来做为研究的主题。
