An Analysis of Service Ontologies

Vikram Sorathia, Luís Ferreira Pires, Marten van Sinderen

Abstract


Services are increasingly shaping the world’s economic activity. Service provision and
consumption have been profiting from advances in ICT, but the decentralization and
heterogeneity of the involved service entities still pose engineering challenges. One of these
challenges is to achieve semantic interoperability among these autonomous entities. Semantic
web technology aims at addressing this challenge on a large scale, and has matured over the
last years. This is evident from the various efforts reported in the literature in which service
knowledge is represented in terms of ontologies developed either in individual research projects
or in standardization bodies. This paper aims at analyzing the most relevant service ontologies
available today for their suitability to cope with the service semantic interoperability challenge.
We take the vision of the Internet of Services (IoS) as our motivation to identify the requirements
for service ontologies. We adopt a formal approach to ontology design and evaluation in our
analysis. We start by defining informal competency questions derived from a motivating
scenario, and we identify relevant concepts and properties in service ontologies that match the
formal ontological representation of these questions. We analyze the service ontologies with our
concepts and questions, so that each ontology is positioned and evaluated according to its utility.
The gaps we identify as the result of our analysis provide an indication of open challenges and
future work.
