Searching useful information without fault from the Web becomes an increasingly difficult task, since the volume of Web data rapidly grows. With the growth rate, unexpected faults of Web service composition may occur in different levels at runtime. These faults are to be identified from Web Log files. The common causes of faults in Web services execution are rectified by fault diagnosis technique...
Earth Observation time-series data are valuable information to monitor the change of the environment. But access to data and the execution of analysis tools are often time-consuming tasks and data processing knowledge is required. In order to allow user-friendly applications to be built, tools are needed to simplify the access to data archives and the analysis of such time-series data. In this work,...
Monitoring and management of large scale applications is already a complex task because of syntactic and unstructured nature of execution data. Traditional application monitoring and management solutions focused on employing analysis techniques on unstructured and syntactic log information become limited as unstructured information cannot be well utilized to find out related events information or...
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...
As part of web services life-cycle, providers frequently face decision about changes without a clear understanding of the impact on their clients. The identification of clients' consumption patterns constitute invaluable information to support more effective decisions. In this paper, we present a framework that supports the discovery of service usage profiles, to bring awareness on the distinct groups...
Web service techniques are presented herein for supporting a cloud energy-saving and case-based reasoning information agent. Not only can it explore related technologies to establish a Web service platform, but it can also study how to construct cloud interactive diagrams to employ Web service techniques for extensively and seamlessly integrating energy-saving and a case-based reasoning information...
The paper focuses on developing a cloud energy-saving and data-mining information agent with Web service techniques. It could explore related technologies to establish a Web service platform, and study how to construct cloud interactive diagrams to employ Web service techniques for extensively and seamlessly integrating an energy-saving and data-mining information agent in the Internet. The preliminary...
Service evolution management imposes complex challenges to a service provider. Identifying which changes are necessary and choosing the ones to implement are some of the decisions that providers have to face. The decision making process involves the estimation of change effects to minimize the impact over the direct and indirect clients of the service portfolio. While most existent works address either...
In this paper, a cloud intelligent and energy-saving information interface agent with Web services was presented. The agent can not only explore related technologies to establish Web service platforms, but it can investigate the construction of cloud interactive diagrams using Web service techniques for extensively and seamlessly integrating backend information systems on the Internet. The preliminary...
The paper presents a solution with the server components from a teleassistance / tele-monitoring system to assist elderly persons and/or post-discharged patients. The system consists of units located at the homes of the monitored persons collecting and sending medical and environmental data from sensors and a call centre with a server for recording and monitoring the data. Specialized staff will support...
Relevant data for decision support systems are available everywhere and in various formats. Such data must be integrated into a unified format. Traditional data integration approaches are not adapted to handle complex data. Thus, we exploit the Active XML language for integrating complex data. Its XML part allows to unify, model and store complex data. Moreover, its services part tackles the distributed...
Whenever the question arises how a product, a personality, a technology or some other specific entity is perceived by the public, the blogosphere is a very good source of information. This is what usually interests business users from marketing or PR. Modern search services offer a rich set of tools to monitor or track the blogosphere as a whole, but the analysis with respect to a certain domain is...
Service-oriented systems' distributed ownership has led to an increasing focus on runtime management solutions. Service-oriented systems can change greatly after deployment, hampering their quality and reliability. Their service bindings can change, and providers can modify the internals of their services. Monitoring is critical for these systems to keep track of behavior and discover whether anomalies...
It is quite difficult to acquire criterion knowledge for the condition monitoring and fault diagnosis in machinery. The traditional approach depends on constant summary of experiences from the experts. However, the acquired knowledge is probably inaccurate and inefficient. With the benefit of network, the different companies and users that have the same equipments can be organized to form an integrated...
Monitoring is a promising technique to detect erroneous behavior of a composite service at run-time, which is to complement static verification and validation techniques. One of the most important aspects of monitoring approach is that the specification of the properties without losing expressive power should be as simple as possible, facilitating the developers to represent the properties of the...
Software production line and Web services are two new hot topics in the field of software engineering and distributed computing. How to integrate the two aspects and to put the combinational services software into distributed, reusable, high efficiency, large-scale production, is a new and exciting challenges. This paper presents a service-oriented software production line integration framework based...
Service composition is becoming a hot research point in recent years, especially in distributed peer-to-peer (P2P) network. However, how to guarantee the high-quality composition service performance becomes the key technology and difficulty in P2P network, which draws lots of attention in computer research field. According to the characteristics of distributed network, an adaptive service composition...
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...
Web-oriented Architectures provide a way of designing an IT system by using a variety of Web Procedures, i.e., procedures (or services) called over the Web. The idea of (typically atomic) components that are black boxes, have interfaces, and can be assembled into a larger process is fundamental and has existed since the early days of distributed systems. Two particular types of modern distributed...
Web services exposing run-time behaviour that deviates from their behavioural specifications represent a major threat to the sustainability of a service-oriented ecosystem. It is therefore critical to verify the behavioural conformance of services during run-time. This paper discusses a novel approach for run-time verification of Web services. It proposes the utilisation of Stream X-machines for constructing...
