This paper presents about requirement elicitation in engineering for elderly care mobile application develpoment. As parent growing old, they need more attention especially from their son or daughter. In contrary, their child becomes mature and needs to gain their ideal like attending higher school or college or taking a job at other city. Based on this problem, it needs to keep their relationship...
The development of information systems in healthcare has grown considerably in recent years. With the evolution of systems based on distributed processing, using the Internet and cloud computing systems can develop much more effective and efficient, particularly in the health field. The proposed system involves the creation of databases, distributed or not, with integration of Web services that may...
The paper presents a framework supporting interoperability between software solutions developed to support activities in obstetrics - gynecology department and pediatrics department in a big hospital, experience that can be extended to other similar hospitals. The goal is to improve medical workflow and processes in obstetrics - gynecology and pediatrics departments using standardized communication...
With the development of on line shopping service, more and more web sites appear such as Amazon, Dangdang and so on. In order to satisfy the consumers' contrasting and choosing the same merchandises in different web sites, we present an extractor of extracting images from the result pages of deep web called AIE. This extractor can also get the images from the surface web sites which have some relations...
With the increasing demand for dynamic web service composition, traditional web service registries are no longer adequate in providing precise service selection. To address this problem, the paper proposes a fine-grain structural concept for traditional service registries, called web service community. Efficient semantic-level service enquiry and community management depend on context information...
Web is becoming a programmable platform, with countless services blooming everyday in various forms like Feeds, REST APIs and Widgets, etc. Although the existing technologies, such as Mashups, have reduced the challenges to build new applications by composing these services, it's still far from enabling the non-technical users to solve their situational problems by correlating and consuming these...
The end-to-end QoS negotiation for SLA establishment for composite services involves compound multi-party negotiations in which the composite service provider concurrently negotiates with multiple candidates for each atomic service, selecting the ones that best satisfy the atomic service QoS preferences while ensuring that end-to-end QoS requirements are also fulfilled. In order to negotiate with...
Modern information systems may exploit numerous web services for communication. Each web service may exploit its own XML format for data representation which causes problems with their integration and evolution. Manual integration and management of evolution of the XML formats may be very hard. In this paper, we present a novel method which exploits a conceptual diagram. We introduce an algorithm...
We propose an integrated framework that manages changes in long term composed services. The main procedure of change reaction is presented. One of the most challenging research issues of change management is how to automate the process of change reaction. To address this issue, we propose a semantic support, which centers around a tree-structured Web service ontology. The ontology is expected to provide...
WS-Policy is a standard to express requirements and capabilities in Web service systems. Policies are based on domain-specific assertions. In this paper we present a lightweight approach to semantic annotations of policy assertions. The approach allows matching of requirements and capabilities based not only on the syntactical representation of their corresponding assertions but also on their semantic...
We propose a skyline computation approach that enables service users to optimally access sets of services as an integrated service package. We first present a one pass algorithm based on the observation that a multi-service skyline is completely determined by single service skylines. The skyline is returned after an enumeration on a significantly reduced candidate space. We then develop a dual progressive...
There are two approaches to specifying the composition of Web services: orchestration and choreography. Previous works in Web services selection are mostly based on the orchestration model which focuses on the interactions with a single party. However, in many application scenarios, business goals are achieved by a number of pair-wise interactions among a set of Web services, and there does not exist...
Data intensive applications, e.g. in life sciences, pose new efficiency challenges to the service composition problem. Since today computing power is mainly increased by multiplication of CPU cores, algorithms have to be redesigned to benefit from this evolution. In this paper we present a framework for parallelizing service composition algorithms investigating how to partition the composition problem...
The difficulty of grid-enabled application development is one of the obstacles to employ grid as infrastructure of scientific computing. Although there are many projects, especially grid workflow projects, trying to make grid-enabled application development easier and quicker, the process-based application description model adopted by most of the grid-enabled applications still bothers scientists...
This paper presents a prototype of an expert system to assist in the discovery and analysis of test failure root cause. The prototype application is most useful in a software development scenario where dedicated software test engineers are employed for testing activities, and these test engineers do not have an intimate knowledge of the internal design and implementation of the software under test...
Existed methods for automatic web services composition based on output parameters and input parameters matching relations of services are limited to linear or tree composition plan and malfunction to the netty plan because they ignore relations between services participating in composition. In order to overcome the shortcoming of the existed methods, a new method is proposed in this paper. In this...
Testing conceptually consists of three activities: test case generation, test case execution and verdict assignment. Using online testing, test cases are generated and simultaneously executed (i.e. the complete test scenario is built during test execution). This paper presents a framework that automatically generates and executes tests "online" for conformance testing of a composite of Web...
Service-oriented computing is the new paradigm for distributed applications. A key issue of utilizing web services is to design a scalable service discovery mechanism. Current discovery method based on centralized registries can easily suffer from performance bottleneck in the service network of large scale. To address such problem, this paper presents a dynamic and scalable mechanism for discovery...
Several issues occur with regard to the correctness of interacting business processes in process choreography. These issues are addressed by discussing the notion of compatibility. Compatibility shows ability of correct interaction when combining multiple business processes. This paper intends to provide rules and methods for analyzing compatibility of process models.
Current service composition techniques and tools are mainly designed for use by service oriented architecture (SOA) professionals to solve business problems. This focus on SOA professionals creates challenges for the non-expert users, with limited SOA knowledge, who try to integrate SOA solutions into their online experience. To shelter non-expert users from the complexity of service composition,...
