Monitoring managing large scale applications has always been a crucial and complex task on which enormous efforts and research have been carried out towards making the process efficient, effective and automated. However, the process is still complex, lacks efficiency and effectiveness because execution workflow representation and logging (outcome from real-time execution) is rendered in a syntactic...
The rise of software-as-a-service has led to the development of Web 2.0 application. In many cases, the server's functionality is made publicly available as an instance of Web services. However, these services can't be invoked arbitrarily, and some behavior constraints must be obeyed. This paper explores an approach to generate data-centric properties automatically by mining execution logs.
Web services are an emerging technology to implement and integrate business processes within and across enterprises. Service orientation can be used to decompose complex systems into loosely coupled software components that may run remotely. However, the distributed nature of services complicates the design and analysis of service-oriented systems that support end-to-end business processes. Fortunately,...
Nowadays, location-based services are widely utilized, including identifying user locations, offering traffic status, providing point of interest (POI) information, and guiding routes. At present, users always make use of location-based services via smart phones, and can obtain information anywhere and anytime. However, users easily receive information in which they were not interested. This kind...
Companies comprise a variety of software applications to carry out their business activities. A recurrent challenge is how to make them interoperate with each other which is usually handcrafted, which is a tedious task that increases integration costs. Enterprise Service Buses range amongst the most popular solution to reduce these costs, and they allow to implement integration solutions by means...
The increased number of web services and the continuous need to integrate them into complex business processes have increased the need to enhance the web service discovery and selection processes. Service discovery based on semantics of web services is one of the main needs in service integration and composition. The main current approaches for semantic discovery of services are the keyword-based...
Nowadays applications are increasingly developed based on remote Web services and service composition has become a powerful novel development paradigm. Due to the fact that such applications in the context of Internet are deployed and executed in an open and dynamic environment, adaptability is one of the crucial requirements for developing such applications. In our previous work, we presented a variability-based...
In this paper we propose a service management mechanism based on a relational model, in which all services to be managed are represented, and operations for services are relational operations using SQL. To define the model, we use Web Services Description Language (WSDL) descriptions and extract information. To use SQL for relational operations for service management, we introduce a new operator to...
Users often visit many stores while they compare merchandise in order to purchase the merchandise or merchandise related to it. Given a service providing information such as location of these stores, they can reduce their time and effort spent by wandering around them because they can go straight to these stores. And they can obtain new purchase opportunities because they can know what kinds of related...
Sensory data also known as Geospatial data is collected in-situ or remotely by different types of sensors from different geographic locations, by different agencies and over a period of time. A vast amount of data is processed via Web services. The quality of the techniques, models and algorithms applied along the processing chain in transforming sensory data critically influences the quality of the...
The evolution towards cross-organizational collaboration and interaction patterns has led to the emergence of scalable, Web services-based composition infrastructures. The success of service-oriented architecture (SOA) was mainly influenced by the standardization of composition languages such as BPEL. However, compositions require humans to be in the loop and ways to interface with people in a service-oriented...
Trust problems exist in open distributed service oriented computing environments. A lot of research work has been done on the theories and applications of trust and reputation management in service oriented environment. However, the design expertise on trust is not well documented yet. In this paper we propose to use trust patterns for documenting solutions for trust problems. The main benefit of...
For web service matching using different ontology, a new matching approach based on concept lattice is proposed in the paper. Firstly, a Formal Concept Analysis theory is formed by different ontology mapping. Secondly, a concept lattice structure is presented based on the Formal Concept Analysis and other mapping relations besides equal mapping are defined Then the similarity computing methods based...
Mashup tools are becoming increasingly important enabling users to compose services and processes on the Web. Most existing tools focus on Web-based interfaces, usability, and visual languages for creating mashups. A major challenge that has received limited attention is context-awareness and adaptivity of service mashups. In this paper we focus on two main aspects: First, a service capability model...
There exists a large and underutilized resource of archaeological literature, both formal, such as scholarly journals and less formal in the form of `grey literature'. In the archaeological domain the vast majority of this literature contains some geo-spatial element as well as the expected temporal information and therefore its ease of discovery would be greatly enhanced were it accessible via a...
One of the major challenges faced by the Web services platform is how to compose a more appropriate new value added web service according to the user's requirements and preferences, and adapt it at runtime. To this end, we suggest in this paper a QoS-oriented approach to build more efficient composite web services and personalize this composition on-the-fly by taking into account user context, requirements,...
Virtualization has enabled the use of virtual machine (VM) based resource providers to offer computing power as a service. However, one important feature is to have certainty about the planed or expected performance of the applications that run inside the VMs. Therefore, consolidating the work load of web-based applications, with time-varying resource requirements, should be done in an automated way...
Combination existing Semantic Web services to form a new, reusable and value-added service is an important issue of the Semantic Web Services. In this paper, we proposed a message-driven-based Semantic Web Service Composition (SWSC) model, which is recognizes the semantic connection between Web Services base on Web Services Description Framework for Semantic (RDF4S), and using it modeling inner-relationship...
Context data-driven approach refers to the process of collecting and storing context data from a wide range of context sources as sensors and Web services. This approach differs from existing context-aware applications, where context models and applications are closely related and ignore how the context is derived from sources and interpreted. In this paper, we propose a context data model based on...
The majority of large companies are adopting Service Oriented Architectures, mainly to automate their business processes, both centralized and distributed. This paper will focus on distributed business processes. At the moment there are two interesting ways to implement a distributed business process, via orchestration or choreography. Whereas an orchestration can be thought of as a service composition...
