Full textSoftware systems accessible via the web are built using existing and distributed web services that interact by sending messages. The web service exposes its functionalities through an interface described in a computer-readable format. Other systems interact, without human intervention, with the web service according to a prescribed procedure using the messages of a protocol. Web services can be deployed on cloud platforms. This type of deployment causes a large number of services to be managed at the level of the same directories raising different problems: How to manage these services effectively to facilitate their discovery for a possible composition. Indeed, given a directory, how to define an architecture or even a data structure to optimize the discovery of services, their composition, and their management. Service discovery involves finding one or more services that meet the client’s criteria. The service composition consists of finding many services that can be executed according to a scheme and that satisfy the client’s constraints. As the number of services is constantly increasing, the demand for the design of architectures to provide not only quality service but also rapid responsetime for discovery, selection, and composition, is getting more intense. These architectures must also be easily manageable and maintainable over time. The exploration of communities and index structures correlated with the use of multi-criteria measures could offer an effective solution provided that the data structures, the types of measures, are chosen correctly, and the appropriate techniques. In this thesis, solutions are proposed for the discovery, the selection of services and their composition in such a way as to optimizethe search in terms of response time and the relevance of the results. The performance evaluation of the proposed solutions is carried out using simulation platforms

Full textWeb services are building blocks for modular applications independent of any software or hardware platforms. They implement the service oriented architecture (SOA). Research on Web services mainly focuses on discovery and composition. However, complexity of the Web services space structure and its development must necessarily be taken into account. This cannot be done without using the complex systems science, including the theory of complex networks. In this thesis, we define a set of networks based on Web services composition when Web services are syntactically (WSDL) and semantically (SAWSDL) described. The experimental exploration of these networks can reveal characteristic properties of complex networks (small world property and scale-free distribution). It also shows that these networks have a community structure. This result provides an alternative answer to the problem of Web services classification by domain of interest. Indeed, communities don’t gather Web services with similar functionalities, but Web services that share many interaction relationships. This organization can be used among others, to guide compositions search algorithms. Furthermore, with respect to the classification based on Web services functional similarity for discovery or substitution, we propose a set of network models for syntactic and semantic representations of Web services, reflecting various similarity degrees. The topological analysis of these networks reveals a component structure and internal organization of thecomponents around elementary patterns. This property allows a two-level characterization of the notion of community of similar Web services that highlight the flexibility of this new organizational model. This work opens new perspectives in the issues of service-oriented architecture

Full textAutomatic composition of web services is a challenging task. Many works have considered simplified automata models that abstract away from the structure of messages exchanged by the services. For the domain of secured services we propose a novel approach to automated composition of services based on their security policies. Given a community of services and a goal service, we reduce the problem of composing the goal from services in the community to a security problem where an intruder we call mediator should intercept and redirect messages from the service community and a client service till reaching a satisfying state. We have implemented the algorithm in AVANTSSAR Platform and applied the tool to several case studies. Then we present a tool that compiles the obtained trace describing the execution of a the mediator into its corresponding runnable code. For that we first compute an executable specification as prudent as possible of her role in the orchestration. This specification is expressed in ASLan language, a formal language designed for modeling Web Services tied with security policies. Then we can check with automatic tools that this ASLan specification verifies some required security properties such as secrecy and authentication. If no flaw is found, we compile the specification into a Java servlet that can be used by the mediatior to lead the orchestration

Full textOver the last two decades, Internet has grown exponentially. causing the emergence of web ser-vices and applications that meet the different needs of the consumers. During the same period, the mobile network industry has become ubiquitous, making most users inseparable from their mobile devices. So the combination of mobile technology and web services provides a new paradigm named mobile web services. Thus, the consumption of web services from mobile devices emerges by offering several facilities to users and requiring greater manipulation of these services such as discovery, composition and execution.Indeed, in order for users to find services that meet their requirements, a discovery mechanism is needed. Since requests have become not only more complex, but also more dynamic, a single service that offers simple and primitive functionality has become insufficient to satisfy the complex requirements. Therefore, the combination of multiple services to provide a composite service is more and more requested. We talk about mobile web service discovery and composition. These two paradigms are mutually linked and complementary.The discovery and composition of web services in a mobile environment raise several challenges that do not exist in a traditional (non-mobile) environment. Among these challenges are the limited constraints of the mobile device, called in this work static context, as well as the change of context which is due mainly to the mobility of the device which called dynamic context.In this thesis we propose a framework for the composition of mobile web services encompassing two complementary approaches. A first proposed approach called MobiDisc, speaking about the discovery of mobile web services and a second that proposes a solution to the problem of composition in a dynamic context. Our first approach uses the static context with QoS properties and user preferences in the semantic descriptions of services and the user query to increase the accuracy of the discovery process. As for the second compositional approach, it focuses on the dynamic context that can modify the composition result. The objective is to determine the sensitivity of the services to the dynamic context and to generate composition plans to the user ordered according to a sensitivity value

Full textThe aim of this thesis is to provide a suitable formal semantic framework that supports interoperability ofdifferent formalisms already used to describe and deploy a Web service. In other words, we contribute to thedevelopment of a rigorous mathematical formalism to describe a complex Web service that may change duringexecution and coordinate with other services adaptively. To achieve this goal, the steps of description, selectionand composition constitute the three major issues studied in this thesis.We proposed so, initially, through the use of the K semantic framework the K-WSDL : a Web servicesdescription language endowed with an operational semantics in terms of rewriting rules which can be executedand analyzed in Maude. We introduced, in a second step, WS-Sim, a new approach based on the category theorywhich evaluates the behavioral equivalence between services by representing each service by a category and byestablishing formal links (functor) between them. Finally, we present RMop-ECATNet (Refined Meta OpenECATNet): a formal model for the specification of services composition. product of the refinement of the Mop-ECATNets model, introduced initially by [LB14]. We extended and enriched this model at three distinct levels:at the structural, behavioural level and implementation levels

Full textL’avènement du Web sémantique a permis l’apparition d’une nouvelle génération de services Web, dénommés Services Web Sémantiques (SWS) intégrant dans leurs descriptions une dimension sémantique décrivant différents aspects fonctionnels et non fonctionnels d’un service Web. Au niveau de cette thèse, nous proposons un méta-framework stratifié que nous nommons BioMed pour la médiation de services Web dans le domaine bioinformatique, cette médiation est triple, à la fois interprétative, ontologique et inférentielle. Le travail mené consiste à proposer une méthodologie de sémantisation de services Web en proposant un modèle de descriptions canoniques de SWS réconciliant des descriptions hétérogènes créées sous différents frameworks. Une réconciliation tant sémantique qu’ontologique au cours de laquelle les SWS décrits canoniquement s’adossent à une méta-carte ontologique permet de pallier à l’hétérogénéité des ontologies du domaine. Deux grandes classes de processus sont considérées: la découverte et la composition de SWS. Ces deux processus sont effectués à travers un moteur inférentiel Datalog-like conçu comme un méta-service Web déductif et sur la base d’une sémantique inférentielle élargissant la couverture sémantique des descriptions et l’espace de recherche des services atomiques et celui des services composables dans le cas d’une composition. Les expérimentations montrent l’impact des techniques de relaxation sur la taille de l’espace de recherche des services découverts. Enfin, nous proposons différentes alternatives afin de classer l’ensemble des solutions et cela afin de déceler les meilleurs services atomiques et/ou plans de composition

Full textScientists have developed the Virtual Observatory (VO) concept in order to make the most of the large masses of heterogeneous data produced by the modern scientific instruments of astrophysics. It is a service-oriented architecture, aiming to facilitate the identification and interoperability of astrophysical data. Despite the development and advances made by VO in the exploitation of these data, some objectives are partially such as interoperability, service selection and identification of related services, etc. In addition, the ergonomics of the tools available to the end user can be improved. Similarly, the current use of VO resources, based on human skills, would benefit from being automated. As not all the astrophysical data services are included in the VO, it would also be desirable to allow a wider use of these tools, as they also rely on services available outside the VO. In order to automate the use of online resources, information sciences have been working since 2001 on the development of the Semantic Web. This evolution provides the Web with automatic reasoning abilities, based on algorithms using a new form of content description. This new form of semantic description is expressed in computer representations called ontologies. Unfortunately, the current semantic Web development methods are not fully compatible with VO services that use data models, formats and protocols for accessing services that differ from those typically encountered in information sciences. In this context, this thesis describes a generic methodology for the composition of stateless services, based on the description of services by a global ontology, the definition of which is proposed in this document. This ontology represents both Web services and services that are not accessible via the Web. It takes into account certain specificities that may be encountered in preexisting service infrastructures. The enrichment of the ontology by concepts derived from specific fields of application for which there are only a few ontological representations is also taken into account. The population of this ontology, by services possibly distant from the standards usually used in the information sciences, is also treated. The methodology was applied successfully in the framework of astrophysics, and allowed to develop a Web application allowing the automatic composition of services usable by an uninformed public

Full textLe standard de description de services Web WSDL ne permet qu'une représentation des aspects fonctionnels des services (méthode, paramètres échangés, et protocole d'accès). Afin de faciliter les étapes de recherche et de sélection effectuées par les clients, la représentation de services doit être enrichie des aspects liés au domaine d'application auquel les services sont dédiés, les aspects non fonctionnels (tels que la description du fournisseur et des contraintes d'exécution) et le contexte d'utilisation auquel les services s'adaptent. Le modèle de représentation de services Web proposé, appelé WSR-Model, fournit l'ensemble de ces catégories d'informations afin que les fournisseurs publient leurs services et que les clients réalisent les étapes de recherche et de sélection. Ce modèle est opérationnalisé via le système de représentation de connaissances par objets AROM qui implémente le registre de services Web, que nous nommons WSR.
La composition de services Web repose sur une description de la planification des services et sur l'exécution de cette planification. À ce jour, les solutions existantes ne prennent pas en compte l'évolutivité de la composition et la prise en compte de l'adaptation au contexte d'utilisation lors des phases de description et d'exécution de la composition. Nous proposons un modèle de composition de services Web, appelé ProbCWS, qui s'appuie sur les méthodes de résolution de problèmes à base de modèle de tâches. La définition de la composition est définie comme un problème à résoudre, dont les tâches de résolution de plus faible granularité sont des services Web. La plate-forme de génération d'applications adaptées, nommée GenAWS et intégrant ProbCWS, fournit aux clients un moyen de composer à la volée des applications adaptées. La mise en oeuvre de GenAWS est réalisée, entre autres, par le langage de résolution de problèmes AROMTasks, sous-jacent au système AROM.

Full textThis thesis concerns the domain of applications adapted to use context issued from the field of Service Oriented Architecture. This type of architecture enhances the cooperation between service providers and service consumers that design SOA applications. In order to help consumers, finding the service that best suits theirs needs, the services must be described by the provider following a given description standard. This description allows services to be discovered, reused and integrated in new applications. The composition of several services must yield results adapted to the use context (user, localization, time, access device). We propose in this work a solution that encloses the description, the retrieval and the composition of services and that takes into account at all levels the adaptation to the use context. The standard for Web service description, WSDL, concerns only the functional aspects of services (methods, parameters, access protocol). For facilitating the retrieval and the selection, the representation of Web Services has to be enriched with information related to the application domains, to the non-functional aspects (such as, description of the provider, execution constraints) and to the use context for which the service was conceived. The model for Web Service representation, called WSR-Model, covers the above information categories in order to enhance the publication, the retrieval and the selection of Web service. This model is supported by a register called WSR, which was implemented using AROM, an object based knowledge representation system. The composition of Web services is based on the description of the execution plan of a collection of services. Nowadays, the existing solutions do not take into account the evolution of such compositions nor the adaptation to the use context. We propose a composition model, called ProbCWS, which transposes the problem solving methods based on task models to Web service compositions. A composition is defined as a decomposable problem for which the fine-grain solving tasks are Web services. The generation framework, called GenAWS, integrates ProbCWS and gives consumers a mean to compose on the fly adapted applications. GenAWS takes advantage of AROMTasks, a problem solving language that is part of AROM framework

Full textBuilding a software system from existing software blocks is not a new idea. These blocks are sometimes called objects, sometimes components, modules and more recently: Web services. The (Web) service-oriented architecture is a paradigm for organizing and using distributed expertise, and its main characteristics are low coupling, flexibility, openness, heterogeneity, scalability or reuse. The ability of a service-oriented architecture to be agile, meaning that it can be modified dynamically while running, is really important to cope with changes of various kinds. Promoting agile architectures, dynamically modifiable, implementing services compositions while guaranteeing a certain quality of service, is a real challenge. The approach developed in the scope of this thesis to address such a challenge is called Diapason. Diapason is a formal approach, based on pi-calculus and temporal logic; it is part of the architecture centric approaches. Diapason offers a services orchestration language (the pi-Diapason language), and a properties description language (the Diapason* language). This approach also provides an initial answer to the dynamic evolution of a running Web services orchestration. Pi-Diapason is formally defined and based on pi-calculus, moreover it offers a syntax specific to the field of Web services orchestration. On the first hand, this language is executable without any ambiguity thanks to a formal operational semantics, and on the other hand it provides the opportunity to develop a dynamic architecture through the concept of mobility introduced by the pi-calculus. Diapason* is a language of the temporal tree logic class based on actions and allows the analysis of any orchestration described in pi-Diapason. The Diapason approach is supported by an environment that includes a pi-Diapason virtual machine (also providing mechanisms to enable the dynamic evolution of an orchestration throughout its execution) and a model-checker

Full textThe Web services orchestration approach described by the Web Service-Business Process Execution Language (WS-BPEL), is now an integral part of the modern Web, such as cloud computing, Big Data, the Internet of Things (IoT) and social networks. Indeed, it is at the center of many information systems related to a variety of domains such as e-commerce, financial institutions and healthcare systems, etc. where sensitive data is shared, which creates significant security issues. WS-BPEL, also called BPEL, is the standard language for building complex Web services in a practical way. However, BPEL is not rigorously defined as a formal language thus leading to problems of ambiguity and confusion when understanding it. Moreover, without a formal basis, it would not be possible to provide any proof guaranteeing the proper functioning of services. This thesis addresses the formalization of BPEL and presents a formal approach based on the rewriting of programs allowing the enforcement of security policies on this language. More precisely, given a composition of Web services specified in BPEL and a security policy described in a temporal logic like LTL, our approach aims to generate a new version of the Web service which respects the given security policy. The new version of the service behaves exactly like the original one except when the policy is about to be violated. In this case the process could take other actions or simply be stopped. The formalization of BPEL has also been translated into the K-Framework environment, which opens the door to the use of its many formal tools including a model checker for the analysis of Web services.

Full textThis thesis addresses the problem of service composition. We focus on the use of planning techniques and we introduce two different approaches that overcome some limitations of the existing approaches. The first approach has two centralized algorithms based respectively on Tree-seach and Graphplan. These algorithms do not scale up well due to their exponential complexity. In the second approach, we overcome this limitation by proposing a multi-agents planning architecture where each web service defined by a set of services and is considered as an agent. The agents are coordinated by merging their best partial plan that answer partially to a request. This coordination procedure is repeated iteratively until reaching the goal using a local heuristic function. This approach is then extended by a global heuristics to ensure its completeness if the sub-problems assigned to the agents are dependent. This global heuristic of evaluating the best local plan avoids the wells by considering the intermediate local plans offered by other agents. The study of the complexity of decentralized approaches shows that they are polynomial, and experimental results show that they are able to scale up well for complex problems. Finally, a self-healing services composition agent-based architecture is developed. This architecture is a real integration between the processes of composition, active dignosis, and repair into one planning process

Full textThis thesis deals with service discovery, selection and composition problems. The aim is to fulfill a complex requester query. To do that, we propose a multi-agent approach based on trust and social networks. We define a trust model as a compositional concept that includes social, expert, recommender and cooperation-based component. The social-based component judges whether or not the provider is worthwhile pursuing before using his services. The expert-based component estimates whether or not the service behaves well and as expected. The recommender-based component checks whether or not an agent is reliable and if we can rely on its recommendations. The cooperation-based component allows agents to decide with whom to interact in a service composition. We propose a distributed algorithm for service discovery using trust between agents and referral systems in social networks. We also develop a new method based on a probabilistic model to infer trust between non adjacent agents while taking into account roles of intermediate agents. Finally, we present an original coalition formation process which is incremental, dynamic and overlapping for service composition in social networks. %In particular, our coalition formation process engaging self-interested agents is incremental, dynamic and overlapping. Experimental results show that our multi-agents approaches are efficient, outperforms existing similar ones and can deliver more trustworthy results at low cost of communications

Full textThis thesis was conducted within the PIMI project, financed by the National Agency of the Research. It concerns the modeling, the querying and thecomposition of personal information. We considered that the use and the accessto personal information is context dependent (e.g., social, geographical). More particularly, it aims to support the user when realising online,administrative or personal procedures. In this setting, the tackled problems arethe representation of heterogeneous information, the context-aware personalinformation spaces querying, the automatic form-filling and the automaticrealization of procedures defined at a high level of abstraction by compositionof online available services.To solve these problems, we have developped several contributions. The first oneconcerns the management of the personal information space. We havedefined a model allowing the description of personal information using severaldomain ontologies. Our model can be instantiated on the user's personalinformation with several usability values depending on the context and with ausability degree. We have also proposed two contextualquerying algorithms SQE and FQE which allow to query the recorded information.The second contribution concerns the use of these information by several onlineservices. It presents two use cases. In the case of the automaticforms-filling, we have proposed an algorithm allowing to generate a semanticquery from an annotated form representation. This query is evaluated by usingboth querying algorithms SQE and FQE. Then, in the case of the user objectiverealization (an abstract procedure) by service composition, we have extendedthe Graphplan algorithm to take into account the contextualization of the dataand the access policy rules specified by the user. The latter allows the user toincrease the control of its information and to limit their leaking

Full textRecently, distributed computing systems based on context awareness have been proposing in several domains such as healthcare, logistics and tourism. The study described in this thesis is a part of a broader project of E-Tourism system that provides nomad user, context-aware personalized services. The work of this thesis focuses on the issues raised by web service composition and execution. Web service composition brings benefits of reusing existing services to synthesize the new resulting service that meets users needs. The way to create web service composition normally happens at design time, but this limits choices of services. This thesis presents a novel approach of automated web service composition and execution framework. Our approach aims to compose service operations that fulfill mobile users' requirements expressed in propositional logic and execute the resulting service based on aggregating multi service components. In the proposed framework, we have introduced our planning algorithm based on abstract goal states to search and connect to service operations, by mean of service operation annotations, for an abstract plan. The abstract plan is expected for workflow model of sequencing, paralleling and conditioning among service operations. However, the generated workflow is not in an executable form, this is why we perform the transformation of the workflow into an executable business process. To achieve the business process execution, we defined context based BPMN model for mapping the abstract plan to BPMN semantics. We also propose a new validation algorithm and exploited planning-as-model-checking approach to validate the semantic BPMN model whether it is Well-formed and Well-defined BPMN process. Finally, we implemented the automated service composition and execution framework system in Java platform as a proof of concept. We developed the logical composition and, transformation and validation BPMN algorithms written in Prolog. We have integrated these algorithms into the whole system. From the perspective, we plan to extend our current work and take into account more complex user's scenarios that explicitly and implicitly express other pattern controls and we will also consider the scenarios required for stateful web services

Full textAmbient Intelligence is considered as the major application domain of ubiquitous computing. It aims at implementing intelligent environments to improve the daily activities, the well-being and the safety of users. An ambient environment has a multitude of devices (sensors, actuators), providing atomic ubiquitous services which are distributed and heterogeneous. These atomic services available in these environments, do not directly or fully meet all the requirements and the needs of users. Moreover, these high-level services may involve the interaction of ubiquitous services owned and/or controlled by different structures or domains (i.e. multi-domain environment). In this work, we studied the problems related to the aggregation of atomic ubiquitous services in cooperations and compositions in an ambient multi-domain environment in order to meet users' needs. This study concerns the semantic and behavioral interoperability of high-level composite services and their formal specification. This latter, is based on the Basic Constructive Description Logic, namely, BCDL0 formal model. This work contributes by realizing a semantic framework for the design and formal verification of cooperative processes in the interactive theorem prover Isabelle/HOL. The proposed semantic framework consists of an extensible cooperation ontology, a sound formal specification language of ubiquitous services and a components for mapping the formally proved cooperatives processes to the targeted infrastructures
