Previewing Semantic Web Pipes
In this demo we present a first implementation of Semantic Web Pipes, a powerful tool to build RDF-based mashups. Semantic Web pipes are defined in XML and when executed they fetch RDF graphs on the Web, operate on them, ...
The WSML Rule Languages for the Semantic Web
The Web Service Modeling Language WSML provides a framework for the modeling of ontologies and semantic Web services based on the conceptual model of the Web Service Modeling Ontology. In this paper we describe the two ...
A Logical Framework for Web Service Discovery
Current technologies for Web Services are based on syntactical descriptions and, therefore, lend themselves to only limited amount of automation. Research efforts in Semantic Web Services, such as WSMO, try to overcome ...
What is wrong with Web services Discovery?
Various proposals for automating the discovery of Web services are available. Most of them regard the terms service and Web service as synonymous. We believe these two terms are not equivalent and it is relevant to ...
Dynamic Querying of Mass-Storage RDF Data with Rule-Based Entailment Regimes
RDF Schema (RDFS) as a lightweight ontology language is gaining popularity and, consequently, tools for scalable RDFS inference and querying are needed. SPARQL has become recently aW3C standard for querying RDF data, ...
Entailment for Domain-restricted RDF
We introduce domain-restricted RDF (dRDF) which allows to associate an RDF graph with a fixed, finite domain that interpretations for it may range over. We show that dRDF is a real extension of RDF and discuss impacts on ...
