Taking the construction of STKOS (Science and Technology Knowledge Organization System) Service System in Intelligence 3.0 as the mainline, this paper first analyzes various functions that the system shall have, and designs the overall architecture of the system. Second, it introduces the implementation of the system from the perspectives of STKOS registration, triple retrieval, visual presentation...
Water environmental problems of river basins in china are becoming more and more serious. Whereas, the environmental watchdogs at different levels provide comparatively independent water environmental data and use various kinds of data patterns, which makes it difficult to resolve the problems in a comprehensive way and make a unanimous decision as to how to deal with the worsening water environment...
WPS (web processing service) is the specifications launched by OGC organizations for dealing with space data, which is different from the conventional Web Service. There aren't dedicated workflow environment for WPS service framework, and support of workflow environments in WPS application is the key technical challenges. Some of the workflow environment, such as Shark, still lack of effective implementation...
A major issue in the resource allocation problem, also known as the data and service allocation problem, in a networked organization is the key problem in Web services distribution. A detailed investigation is carried out of the resource allocation model of allocating data and application services across a distributed networking system. The data and application service allocation problem is modeled...
Web is becoming a programmable platform and Mashup is emerging as a brand-new service composition paradigm. However, one of the biggest blocking issues with the universal adoption of Mashup is lack of a well-designed inventory of mashable services for users to create mashups effectively. In this paper, we propose a novel and practical method to conceptualize, model and design the mashable services...
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...
In SOA, services may become volatile and fail to deliver the quality of service as requested by users. In this paper, we present an approach for repairing failed services by replacing them with new services and ensuring the new service process still meets the user specified end-to-end QoS constraints. An iterative structural inspection algorithm is designed to produce reconfiguration regions that...
One of the challenges in SOA is to provide an efficient and effective way to identify compatible Web service(s) and compose them into a service process that satisfies a userpsilas functional and non-functional needs. Quality of service (QoS), like response time or throughput, might need to be optimized for the selected service process. This paper describes a system architecture and strategies Web...
Using SOA, service processes can be composed statically or dynamically using services provided by different service providers. Some services may become faulty at runtime and cause the service process to violate the end-to-end quality of service (QoS) constraint. We propose an efficient approach for replacing faulty services to ensure that the reconfigured service process still meets the original end-to-end...
Loose coupling is a cornerstone for service-oriented architecture (SOA). Service contracts enable loose coupling, because they conceal internal details of services from the outside world behind the facade. However, current works on service oriented analysis and design (SOAD) largely focus on defining processes for developing business processes and services without considering variability in details...
With a widely deployed RFID middleware system either in companies or manufactories, large volumes of collected data can be integrated into enterprise information management system. By combing the technique of Web services, RFID information flow can be exchanged between different information platforms under the universal XML format. However the performance of data transmission causes great concern...
At present, Web applications and HTTP requests on the Internet are so explosively increasing that a large number of hot Web sites frequently confront with problems of server overloading. And how to provide various web services with high-level quality and satisfactory performance for Web clients has become one of the most urgent points we concern. In order to smoothly solve these problems, we proposed...
With the wide application of RFID technology in a variety of fields such as item tracking, supply chain management, theft and counterfeiting prevention and so on, to manage the large volume data collected from a RFID network in manufactory effectively and efficiently poses some challenges. It is necessary to design a RFID middleware to collect data from the production line and deploy it in order to...
Many researchers propose that, not only functional but also non-functional properties, also known as quality of service (QoS), should be taken into consideration when consumers select services. Consumers need to make prediction on quality of unused web services before selecting. Usually, this prediction is based on other consumers' experiences. Being aware of different QoS experiences of consumers,...
