With XML becoming the de facto standard for representing and exchanging data on the Internet, the problem of validation of XML data when updated has attracted more and more attentions. The traditional brute-force validation processes the entire updated XML document from scratch, which is less efficient. This paper presents a method for XML incremental validation based on simplified XML element sequence...
We describe an access control model that has been implemented in the web content management framework “Deme” (which rhymes with “team”). Access control in Deme is an example of what we call “bivalent relation object access control” (BROAC). This model builds on recent work by Giunchiglia et al. on relation-based access control (RelBAC), as well as other work on relational, flexible, fine-grained,...
This article carries information about declarative micro-language on XML base. It is created for strict division of labour between layout-designer and software engineer during web-site development. It allows to describe structure, functionality of software components and page templates. Specialities: 1. URI standard (Uniform resource identifier) is used to call for program areas of web application...
In this paper we present two adaptations of the PageRank algorithm to collections of XML documents and the experimental results obtained for the Wikipedia collection used at INEX-1 2007. These adaptations to which we referred as ldquoDOCRANK and TOPICAL_docrankrdquo allow the re-rank of the results returned by the base run execution to improve retrieval quality. Our experiments are performed on the...
This paper presents a framework for automatically structuring knowledge, in order to reveal the intrinsic relationships among data. The approach exploits a fuzzy extension of Formal Concept Analysis theory, applied to RSS feeds. On the basis of the RSS Feed content, fuzzy FCA generates an ontology oriented knowledge network, enabling the accessibility of web resources presented by feeds. The framework...
Most of the enormous amount of information from the internet is available just like Web pages made for a human reader. They don't have any common interface for accessing, searching or browsing the data. Hence, it's hard to extract the semantic data from the Web, categorize them and keep them updated. For this purpose we have designed and implemented a system called AgentMat. This system is designed...
