Deep Web contents are accessed by queries submitted to Web databases and the returned data records are enwrapped in dynamically generated Web pages (they will be called deep Web pages in this paper). Extracting structured data from deep Web pages is a challenging problem due to the underlying intricate structures of such pages. Until now, a large number of techniques have been proposed to address...
Database is an important part of Web information system, the IO performance of which is a key factor of the responsiveness of the whole system. Existing databases usually adopt magnetic disks as storage devices. Now, low IO performance of magnetic disks becomes the bottle neck to the performance of the entire Web information system. Flash memory, as a new electronic storage device, has high read/write...
As a de facto standard for information representation and exchange over the Internet, XML has been used extensively in many applications. And XML query technology has attracted more and more attention in data management research community. Standard XML query languages, e.g. XPath and XQuery, use twig pattern as a basic unit to match relevant fragments from a given XML document. However, in most existing...
The rapid prevalence of Web and mobile devices are making themselves becoming huge data sources. This new infrastructure presents tremendous challenges for data management technology, and traditional data management technologies such as query processing, transaction management, workflow etc. must all be re-evaluated in this emerging environment. Furthermore, non-traditional issues, such as Web and...
