SparqPlug: Generating Linked Data from Legacy HTML, SPARQL and the DOM
Peter Coetzee, Tom Heath, Enrico Motta · 2008
The availability of linked RDF data remains a significant barrier to the realisation of a Semantic Web. In this paper we present SparqPlug, an approach that uses the SPARQL query language and the HTML Document Object Model to convert legacy HTML data sets into RDF. This framework improves upon existing approaches in a number of ways. For example, it allows the DOM to be queried using the full flexibility of SPARQL and makes converted data automatically available in the Semantic Web. We outline the process of batch conversion to RDF using SparqPlug and illustrate this with a case study. The paper concludes with an examination of factors affecting SparqPlug’s performance across various forms of HTML data.
