Service that can satisfy the functionality required by the user, there should be a program or a software agent which can automatically combine existing ser- vices together in order to fulfill the request the aim of this thesis is to view the web service composition problem from the viewpoint of logic-based program synthesis. A flexible semantic service composition framework for pervasive computing environments a thesis submitted to the graduate school of informatics of the middle east technical university by mustafa özpinar in partial fulfillment of. Reputation-based service composition seminar thesis submitted to the software engineering research group in partial fulfillment of the requirements for the seminar cloud computing and software services by siddhartha moitra thesis supervisor: msc marie christin platenius paderborn, september 2014. Dissertation qos-aware composition of adaptive service-oriented systems ausgeführt zum zwecke der erlangung des akademischen grades eines doktors der technischen wissenschaften unter der leitung von univ-prof dr schahram dustdar distributed systems group institut für. Context as a resource: a service-oriented approach for context-awareness software engineering [csse] 433 framework for autonomic context-aware service composition 53 two major contributions in this dissertation: i) spaces, a middleware approach to integrate con- text information. Qos-aware web service composition using genetic algorithms by lifeng ai a thesis submitted to faculty of science and technology queensland university of technology in partial fulfillment of requirements for the degree of doctor of philosophy june 2011.
This thesis is about investigating and implementing a web service client module for drupal that is able to consume classical ws web services as well as restful web services we will present a web service abstraction model which supports different web service types in order to facilitate integration of web. This thesis deals with automatic dynamic semantic web service composition it discusses the problem of service composition in a wider context and deals with selected sub-problems concerning this topic the sub-problems include the proper description of the behavior of web services, management of the changes in the. Doctoral thesis process mediation framework for semantic web services roman vaculín supervisor: mgr roman neruda, csc co-supervisor: prof katia sycara on process mediation algorithms, discovery of external services, monitoring, and fault handling 212 discovery and composition of web services.
To address these issues, this thesis proposes the web service specification language (wssl), a novel, semantics-aware language for the specification and composition of services, independent of service design models wssl's founda- tion is the fluent calculus, a specification language for robots that offers solutions. These results can be very helpful for service providers, who can then take corrective actions to improve their services as far as the computation of qos for composed web services is concerned, this thesis proposes some basic metric types, provided that we know the composition pattern based on this pattern, appropriate.
Adaserc: advanced analysis of service compositions chair and coordinator: dipl-inf thomas prinz, university of jena, germany [email protected] tracks: trends in service computation cloud services orchestration context- aware adaptation of service-based systems service computation in smart cities. The second component is a service composition model in which ai-based plan- ning using agent technology is adopted to dynamically and flexibly construct composite service workflow in this model, a distributed service dependency model based on and/or graph structure is decomposed and distributed among individ.
Particularly, it concerns the composition/decomposition service design, the verification, and the testing of choreography implementation the first key point of our framework is to support value-passing among services by using symbolic technique and smt solver it overcomes false negatives or state space. The thesis specifies semantics for web service composition standards and develops an accessible, mechanical tool, which automates the tasks involved this thesis presents a model-based approach built upon formal verification, validation and simulation techniques, utilising scenario-based design and implementations.
