Exploring XML web collections with DescribeX

To support modern web applications, we introduce DescribeX, a powerful framework that is capable of describing complex XML summaries of web collections.  ...  DescribeX supports the construction of heterogenous summaries that can be declaratively defined and refined by means of axis path regular expression (AxPREs).  ...  A DTD is a context-free grammar and an XML Schema is a typed definition language. Both are schemas in the database sense, and thus describe classes of documents and constrain their structure.  ...

In this article, we present the XSeq language and system that support CEP on XML streams, via an extension of XPath that is both powerful and amenable to an efficient implementation.  ...  Besides the efficiency and expressivity benefits, the choice of VPA as the underlying model also enables XSeq to go beyond XML streams and be easily applicable to any data with both sequential and hierarchical  ...  ACKNOWLEDGMENTS We would like to thank the reviewers, Balder ten Cate, Alexander Shkapsky, Nikolay Laptev and Shi Gao for their comments.  ...
