Design and implementation of a filter engine for semantic web documents
This report describes our project that addresses the challenge of changes in the semantic web. Some studies have already been done for the so-called adaptive semantic web, such as applying inferring rules. In this study, we apply the technology of Event Notification System (ENS). Treating changes as events, we
developed a notification system for such events
Supporting SPARQL Update Queries in RDF-XML Integration
The Web of Data encourages organizations and companies to publish their data
according to the Linked Data practices and offer SPARQL endpoints. On the other
hand, the dominant standard for information exchange is XML. The SPARQL2XQuery
Framework focuses on the automatic translation of SPARQL queries in XQuery
expressions in order to access XML data across the Web. In this paper, we
outline our ongoing work on supporting update queries in the RDF-XML
integration scenario.Comment: 13th International Semantic Web Conference (ISWC '14
Structural matching by discrete relaxation
This paper describes a Bayesian framework for performing relational graph matching by discrete relaxation. Our basic aim is to draw on this framework to provide a comparative evaluation of a number of contrasting approaches to relational matching. Broadly speaking there are two main aspects to this study. Firstly we locus on the issue of how relational inexactness may be quantified. We illustrate that several popular relational distance measures can be recovered as specific limiting cases of the Bayesian consistency measure. The second aspect of our comparison concerns the way in which structural inexactness is controlled. We investigate three different realizations ai the matching process which draw on contrasting control models. The main conclusion of our study is that the active process of graph-editing outperforms the alternatives in terms of its ability to effectively control a large population of contaminating clutter
