However, the algorithm requires users to know more about query not only the language facilitated in structured query algorithm but also the structure of the query XML document tree. The above requirements are impractical for most users. 然而,该算法对进行查询的用户也提出了更高的要求,即不仅要熟悉结构查询算法所采用的查询语言,而且还要了解待查询的XML文档树结构。
This paper discusses the issue of meaningful result determination for non-fully structured query ( NFS ) and proposes a scalable PE model to determine meaningful results based on the concept of pattern and entity. 讨论了有意义的非完全结构XML查询(NFS)结果的定义,提出了一种易于扩展的基于模式和实体的有意义判断模型&PE模型;
