模式匹配方法研究

从模式匹配的定义开始介绍，对已有的模式匹配方法进行分类，探讨了这些方法适用的领域和所能发掘的信息，区分了实例级和模式级、元素级和结构级以及基于自然语言和基于约束的匹配程序，以期在比较不同模式匹配方法或研究新匹配算法以及实现模式匹配组件时有所帮助。

Research on Schema Matching Approaches

First introduced the definition of schema matching, then classified the existing approaches on schema matching, and studied what kind of information they can exploit, distinguished between schema-level and instance-level, element-level and structure-level, and language-based and constraint-based matcher. It is expected to be useful when comparing different approaches of schema matching, when researching a new match algorithm, and when implementing a schema matching component.
