The role of models@run.time in supporting on-the-fly interoperability

N. Bencomo, A. Bennaceur, P. Grace, G. Blair, V. Issarny
2012 Computing  
This paper focuses on this novel use of models at runtime, examining in detail the nature of such runtime models coupled with consideration of the supportive algorithms and tools that extract this knowledge  ...  Models at runtime can be defined as abstract representations of a system, including its structure and behaviour, which exist in tandem with the given system during the actual execution time of that system  ...  The authors would like to thank Antoine Leger from Thales for valuable input about the GMES case study.  ...

Hybrid approach for context-aware service discovery in healthcare domain

G. Fenza, D. Furno, V. Loia
2012 Journal of computer and system sciences (Print)  
Semantic formalisms (e.g., OWL, OWL-S, etc.) enable the context and services modeling in terms of domain ontology concepts.  ...  Specifically, the system exploits some task oriented agents in order to achieve context recognition, services matchmaking and brokerage activities.  ...  Since the data context are modeled by means of ontologies the concepts in the rules are associated with their semantic specification.  ...

2007 ACM Transactions on Internet Technology  
In particular, a context-based mediation approach to solve semantic heterogeneities between composed Web services is presented.  ...  However, despite the widespread adoption of Web services, several obstacles still hinder their smooth automatic semantic reconciliation when being composed.  ...  In order to complete the context C, rules help infer the values of dynamic modifiers at runtime.  ...

CoOL: A Context Ontology Language to Enable Contextual Interoperability [chapter]

Thomas Strang, Claudia Linnhoff-Popien, Korbinian Frank
2003 Lecture Notes in Computer Science  
A core component of this architecture is a reasoner which infers conclusions about the context based on an ontology built with CoOL.  ...  A Context Ontology Language (CoOL) is derived from the model, which may be used to enable context-awareness and contextual interoperability during service discovery and execution in a proposed distributed  ...  By resolving the binding between the parameters of a service call and information from a context provider (context binding) at runtime, the intermediate is a central component in our architecture to enable  ...

Information Modeling for End to End Composition of Semantic Web Services [chapter]

Arun Kumar, Biplav Srivastava, Sumit Mittal
2005 Lecture Notes in Computer Science  
One of the main goals of the semantic web services effort is to enable automated composition of web services.  ...  An end-to-end view of the service composition process involves automation of composite service creation, development of executable workflows and deployment on an execution environment.  ...  The context for the inputs and outputs need to be made explicit. One provision to model the semantics associated with the input/output parameters is by creating new concepts in the domain ontology.  ...

Domain-specific summarization of Life-Science e-experiments from provenance traces

Alban Gaignard, Johan Montagnat, Bernard Gibaud, Germain Forestier, Tristan Glatard
2014 Journal of Web Semantics  
In this paper, we propose an integrated approach in which Life-Science knowledge is (i) captured through domain ontologies and linked to Life-Science data analysis tools, and (ii) propagated through rules  ...  Our approach has been implemented in the Virtual Imaging Platform (VIP) and experimental results show the feasibility of producing few domain-specific statements which opens new data sharing and repurposing  ...  We would also like to thank Olivier Corby and Catherine Faron Zucker for their support and advises regarding the Corese/KGRAM Semantic Web engine.  ...

Using context to enable semantic mediation in web service communities

2008 Proceedings of the 2008 international workshop on Context enabled source and service selection, integration and adaptation organized with the 17th International World Wide Web Conference (WWW 2008) - CSSSIA '08  
We rely on a semantic annotation of WSDL descriptions to describe the semantics attached to Web services, and we provide mediation mechanisms at the community level to handle semantic heterogeneities between  ...  However, Web services adopt different semantics for representing the data they receive and send. These semantics must be adapted to conforming to the community semantics.  ...  Experts in the knowledge domain should specify domain ontologies and limit to the minimum the further description of domain concepts.  ...
