Web Service Capabilities and Constraints in WSMO
(2004)
This paper summarizes the necessities on the semantic modeling of Web Service constraints and capabilities from the viewpoint of the Web Service Modeling Ontology(WSMO) working group. We will give a short motivating use ...
A Logical Framework for Web Service Discovery
(IEEE, 2004)
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 ...
Towards Fine-grained Service Matchmaking by Using Concept Similarity
(2007)
Several description frameworks to semantically describe and match services on the one hand and service requests on the other have been presented in the literature. Many of the current proposals for defining notions of ...
dlvhex-sparql: A SPARQL-compliant query engine based on dlvhex
(CEUR, 2007)
This paper describes the dlvhex SPARQL plugin, a query processor for the upcoming Semantic Web query language standard by W3C. We report on the implementation of this languages using dlvhex, a flexible plugin system ...
Towards a social provenance model for the Web
(2007)
In this position paper we firstly present the established notion of provenance on the Semantic Web (also referred to as named graphs or contexts), and secondly argue for the benefit of adding to the pure technical notion ...
Scalable Authoritative OWL Reasoning on a Billion Triples
(2008)
In this paper we present a scalable algorithm for performing a subset of OWL reasoning over web data using a rule-based approach to forward-chaining; in particular, we identify the problem of ontology hijacking: new ...
Previewing Semantic Web Pipes
(Springer, 2008)
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
(2005)
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 ...
SPARQL++ for mapping between RDF vocabularies
(Springer, 2007)
Lightweight ontologies in the formof RDF vocabularies such as SIOC, FOAF, vCard, etc. are increasingly being used and exported by ¿serious¿ applications recently. Such vocabularies, together with query languages like SPARQL ...
