Chung-Wei Hang, Anup K. Kalia, Munindar P. Singh
2012 2012 IEEE 19th International Conference on Web Services  
Our experiments show that our approach can dynamically punish or reward the constituents of composite services while making only partial observations.  ...  ; (2) evidence must be combined from multiple sources; (3) service profiles change dynamically; and (4) constituent services may be only partially observable behind composite services.  ...  The error of predicting trust of constituent services using BMPO with varying percentages of partial observations.  ...

Automated Composition of Semantic Web Services into Executable Processes [chapter]

Paolo Traverso, Marco Pistore
2004 Lecture Notes in Computer Science  
We propose a planning technique for the automated composition of web services described in OWL-S process models, which can deal effectively with nondeterminism, partial observability, and complex goals  ...  However, in realistic cases, the planning problem is far from trivial: the planner needs to deal with the nondeterministic behaviour of web services, the partial observability of their internal status,  ...  partial observability.  ...

This paper gives a survey on the current state of Web Service Compositions and the difficulties and solutions to automated Web Service Compositions.  ...  This first gives a definition of Web Service Composition and the motivation and goal of it. It then explores into why we need automated Web Service Compositions and formally defines the domains.  ...  ACKNOWLEDGEMENTS The inclusion of images and examples from external sources is only for non-commercial educational purposes, and their use is hereby acknowledged.  ...

Trustworthy Service Selection and Composition

Chung-Wei Hang, Munindar P. Singh
2011 ACM Transactions on Autonomous and Adaptive Systems  
Our results show that both approaches accurately punish and reward services in terms of the qualities they offer, and further that the approaches are effective despite incomplete observations regarding  ...  Existing approaches for service selection either fail to capture the dynamic relationships between services or assume that the environment is fully observable.  ...  Acknowledgments This work was partially supported by the U.S. Army Research Office (ARO) under grant W911NF-08-1-0105 managed by the NCSU Secure Open Systems Initiative (SOSI).  ...

Composition of Services with Nondeterministic Observable Behavior [chapter]

Daniela Berardi, Diego Calvanese, Giuseppe De Giacomo, Massimo Mecella
2005 Lecture Notes in Computer Science  
In [3] we started studying an advanced form of service composition where available services were modeled as deterministic finite transition systems, describing the possible conversations they can have  ...  In the present paper we complete such a line of investigation, by considering the case in which the available services are only partially controllable and must be modeled as nondeterministic finite transition  ...  Conclusion In this paper we studied how to synthesize a composition to realize a client service request expressed as a target service a la [3, 4] , in the case where available services are only partially  ...

Effect of Partial Shear Interaction in Steel Concrete Composite Girders

Madhusudan G. Kalibhat, Akhil Upadhyay
2017 IOP Conference Series: Materials Science and Engineering  
It has been observed that generally the composite action exists somewhere between the full composite action and the no composite action, and is called the partial composite action or the partial interaction  ...  It is observed that there is significant increase in deformations of the SCC girder, on account of the partial interaction.  ...  Effect of partial composite action The partial composite action or degree of shear interaction is defined as the ratio of number of shear connectors provided to the number of shear connectors required  ...

Automatic service composition using POMDP and provenance data

Mahsa Naseri, Simone A. Ludwig
2013 2013 IEEE Symposium on Computational Intelligence and Data Mining (CIDM)  
In this research, we argue that due to partial observability of service and system states, the POMDP approach provides better solutions for the QoS-aware service composition in dynamic workflow environments  ...  In service composition, the composition of services identifies this path.  ...  agent to act optimally in partially observable domains.  ...

ComposingWeb Services with Nondeterministic Behavior

Daniela Berardi, Giuseppe Giacomo, Massimo Mecella, Diego Calvanese
2006 2006 IEEE International Conference on Web Services (ICWS'06)  
In other words, the behavior of the service is partially controllable, and the orchestrator needs to cope with such partial controllability.  ...  The promise of Web services is to enable the composition of new distributed applications/solutions: when no available service can satisfy a client request, (parts of) available services can be composed  ...  The contribution of this work is to devise a formal technique to perform automatic composition synthesis, when available services are nondeterministic and hence partially controllable by the orchestrator  ...

Then, a composite service can be statically predefined without regarding peculiarities and requirements of single business cases.  ...  In the simplest case, all business cases of a particular kind follow the same external services and internal procedures.  ...  Partial service pool: The partial service pool comprises service instances capable of fulfilling a specific part of the generic activity.  ...

Behavioural description based web service composition using abstraction and refinement

Hyunyoung Kil, Wonhong Nam, Dongwon Lee
2013 International Journal of Web and Grid Services  
Despite its importance, however, solving the problem for a general case (when the coordinator has only partial observations) remains doubly exponential in the number of variables in web service descriptions  ...  The web service composition problem with respect to behavioural descriptions deals with the automatic synthesis of a coordinator web service that controls a set of web services to reach a goal state.  ...  Acknowledgements This research was partially supported by the MKE (Ministry of Knowledge Economy), Korea, under the ITRC (Information Technology Research Center) support program supervised by the NIPA  ...
