Cloud computing technology is a new paradigm which provides Information Technology (IT) resources via the Internet. This new shift in the way that IT re-sources are offered to the user brings new challenges, such as cloud service discovery. Nowadays, cloud users are faced with a dilemma as they have an abundant choice of cloud services. Moreover, many cloud providers offer a range of services which...
In the last few years, O2O (Online To Offline) mode become more and more popular, which brings offline service and online web service together, it is important to consider the quality attributes of offline service when recommending service for users online. But in the field of service discovery system, most of the studies focused on function and quality requirements of online service, not on offline...
Future Networks constitute a complex and dynamic environment which network operators are called to orchestrate uniformly and efficiently. Among others, the increase in the number and heterogeneity of network infrastructure, the complexity of devices and protocols and the explosion in traffic demands are only “few” of the issues that network operators should take into consideration. Conventional network...
Performance evaluation of faculty members in a higher education is a serious challenge for management. Several qualitative and quantitative factors are considered leading to targeted professional growth of an organization to evaluate the performance, such as acquiring research grants, research profile, student evaluation, publications, academic responsibilities etc. However, to quantify such information...
Web services are forms of Internet software that can be integrated into a composite service using standard protocols regardless of their locations, platforms, and execution speeds to implement complex business. However, a large number of web services with similar function attributes but different QoS attributes are available, and selecting optimal component services from candidate services has become...
Web service discovery is the process of locating web services to satisfy the requirements of service requesters. It plays an important role in building loosely coupled service-oriented applications. Nowadays, although many service discovery mechanisms are available, a lot of efforts do not focus on linking actual business services in real world and most methods do not provide an appropriate relaxation...
The emergence of new technologies and services forces the network operator to manage uniformly and efficiently the complex network environment of Future Networks. The interworking of multiple underlying heterogeneous network domains with proprietary network management systems is currently a tedious task, and this fact will be exacerbated in the near future. To this end, we address the challenge of...
Web service is a new application model for the data and service integration on the web. Due to insufficient semantic information, dynamic services composition is difficult to accomplish. Thus, a new composition framework based on web process model is presented, which allows the process designers to design processes, based on business and process constraints. Our approach achieved the optimal selection...
This paper addresses the problem of BPM and SOA integration presenting a model of dynamic discovery of services as an approach to improve the agility of SOA-based applications. Many researches have tackled the discovery problem. However, in general they fail in discovering the most suitable service regarding business processes needs. The main contribution of this work is to offer a comprehensive,...
Together with the diffusion of the Internet both private and legal persons have designed a wide variety of information intensive services. At the same time, concepts and methods have been developed to facilitate the description, discovery, composition, and consumption of these services. However, the selection of the right service still represents a major problem for consumers, since policy-, reputation-...
The combination of BPM&SOA has been considered a powerful strategy for companies to be more agile. However, integrating BPM and SOA has many challenges especially when composition of applications is envisaged. The main contribution of this work is to propose an integrated model that deals with the problem of service discovery over largely distributed software services providers, including QoS...
Web Services are emerging technologies that enable application to application communication and reuse of autonomous services over Web. Composition of web services is a concept of integrating individual web services to conduct complex business transactions based on functionality and performance constraints. To simplify composite web service development, technologies of quality of service (QoS) based...
Service composition is a new paradigm for efficient and cost-effective IT service provisioning over the network. To safely and effectively deploy composed services within an organization or among multiple domains, one must be able to specify and enforce a variety of constraints such as those derived from legal regulations, Quality of Service (QoS) requirements and privacy and security policies. In...
In a distributed service-oriented computing environment, service consumers like to obtain guarantees related to services which they use provided by web service provider. Web service agreement specification is to define a language and protocol for advertising the capabilities of service providers. As the current version of web service agreement can not provides enough semantic expression. This work...
Automated composition of web services is a crucial aspect of web services technology, which gives us the opportunity for selecting new services and best suits our needs at the moment. Doing this automatically would require us to compute our criteria for composing candidate services. In addition, there are challenging issues of correctness and optimality. A framework is designed in this paper represent...
The evolution of services market raises the need for automatic support for negotiating service use criteria. In order to reach an agreement, the negotiating parties need to develop a common understanding of the Quality of Service (QoS) terms which are part of the Service Level Agreement (SLA). The use of semantic annotations together with reasoning can increase the level of flexibility and automation...
Service oriented architecture (SOA) is becoming the architectural style of choice in many enterprises that adopt the notion of business process architecture. This suggests the need for a systematic and unified approach to generate a service model from a given organizational business process architecture. This paper presents a generic framework called BPAOntoSOA which addresses this requirement. BPAOntoSOA...
This paper proposes a new method for the automatic composition of semantic Web services. The proposed method consists in constructing a graph and then searching for a sub-graph of this graph, which will represent a candidate composition solution. First, the method constructs a directed acyclic graph, which represents the functional semantics of the Web services as well as the semantic dependency between...
Syntactic composition languages like BPEL, WSCI are insufficient for end users because of many technical details. In order to reduce the complexity of service composition, various approaches based on semantic technologies and planning techniques have been developed for automatic service composition. However these approaches have focused on composition aspects and have not facilitated users expressing...
Semantic Web Service technology provides a strong support for automation software development based on Web service. By analyzing the existing description models and methods of semantic Web service, a Semantic Web Service Description Model (WSDM4S) and its formal description based on SHOIN+(D) are proposed, which attempt to offer an effective model for description, publication, discovery, composition,...
