Research ArticleOpen accessIn the author namesTwigX-Guide: Twig Query Pattern Matching for XML TreesSu-Cheng Haw, Chien-Sing LeeThe growing importance of XML and the lack of efficient solutions for managing and querying XML data have led to the development of hybrid systems. We present a hybrid system, TwigX-Guide; an extension of the well-known DataGuide index and region encoding labeling to support twig query processing. With TwigX-Guide, a complex query can be decomposed into a set of path … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the author namesTwigINLAB: A Decomposition-Matching-Merging Approach To Improving XML Query ProcessingSu-Cheng Haw, Chien-Sing LeeThe emergence of the Web has increased significant interests in querying XML data. Current methods for XML query processing still suffers from producing large intermediate results and are not efficient in supporting query with mixed types of relationships. We propose the TwigINLAB algorithm to process and optimize the query evaluation. Our TwigINLAB adopts the decomposition-matching-merging approach and focuses on optimizing … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 6,988 accessesView PDFCite
