WEBVIGIL: MONITORING MULTIPLE WEB PAGES AND PRESENTATION OF XML PAGES

S. Chamakura, A. Sachde, S. Chakravarthy, A. Arora
2005 21st International Conference on Data Engineering Workshops (ICDEW'05)  
As there are no presentation semantics and tags, manual identification of the detected changes is difficult on a XML web page.  ...  Once detected, changes have to be notified to the user in a meaningful manner. In this paper we also propose various presentation schemes to display the changes computed on XML pages.  ...  Unlike WebCQ, WebVigiL is capable of detecting changes to one level in depth of a web page.  ...
