Abstract

To realize a wide range of applications (including digital libraries) on the Web, a more structured way of accessing the Web is required and such requirement can be facilitated by the use of XML standard. In this paper, we propose a general framework for reverse engineering (or re-engineering) the underlying structures i.e.,the DTD from a collection of similarly structured XML documents when they share some common but unknown DTDs. The essential data structures and algorithms for the DTD generation have been delveloped and experiments on real Web collections have been conducted to demonstrate their feasibilty. In addition, we also proposed a method ofimposing a constraint on the repetitiveness on the element in a DTD rule to further simplify the generated DTD without compromising their correctness.

从Web文档重新设计结构

为了在Web上实现广泛的应用程序(包括数字图书馆)，需要一种更加结构化的访问Web的方式，而XML标准的使用可以促进这种需求。在本文中，我们提出了一个通用框架，用于对底层结构进行逆向工程(或重新工程)，即，当一组结构相似的XML文档共享一些常见但未知的DTD时，从它们中提取DTD。开发了生成DTD的基本数据结构和算法，并在实际Web集合上进行了实验以证明其可行性。此外，我们还提出了一种对DTD规则中元素的重复性施加约束的方法，以进一步简化生成的DTD而不影响其正确性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
