Under the loosely coupled SoS's dynamic and uncertain running environment, self-healing process, as the important safeguard mechanism of system running, pose a great threat to system quality analysis. Particularly, as the first step of self-healing, the research of quality failure prediction faces not only continual and immediate disturbance on service quality, but also complex users' preference on quality. In this paper, we propose a model based on Stochastic Differential Equations to analyze the disturbance more precisely and dynamically. And we adopt weighted conditional preference to consider different users' requirements. This model is testified in an empirical case study, in which the real data set is collected in real-time from the system platform of a Telecom in China. The experiments verify model's prediction abilities and evaluate the impact of the parameters on the prediction accuracy.","PeriodicalId":215397,"journal":{"name":"2014 IEEE International Conference on Web Services","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134481736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a collaborative approach to quality-of-service (QoS) prediction of web services on unbalanced data distribution by utilizing the past usage history of service users. It avoids expensive and time-consuming web service invocations. There existed several methods which search top-k similar users or services in predicting QoS values of Web services, but they did not consider unbalanced data distribution. Then, we improve existed methods in similar neighbors' selection by sampling importance resampling. To validate our approach, large-scale experiments are conducted based on a real-world Web service dataset, WSDream. The results show that our proposed approach achieves higher prediction accuracy than other approaches.","PeriodicalId":215397,"journal":{"name":"2014 IEEE International Conference on Web Services","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127079348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With a vast variety of Web Services being offered by service providers, annotation techniques that add tags to services automatically are frequently exploited with the aim of retrieving relevant services faster. Tagging of Web Services at finer levels of granularity can assist in drawing more detailed conclusions, making their use easier. In this paper, we go beyond global Web Service tagging by proposing a classification technique for the annotation of Web Service sections. The process focuses on port type, operation and message sections of the service description. Service information as offered through WSDL and the provider and user descriptions is considered. The initial evaluation results demonstrate the efficiency of the approach in providing annotations at these different service levels.","PeriodicalId":215397,"journal":{"name":"2014 IEEE International Conference on Web Services","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133779106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though, web service composition has been an important area of research in the last decade, however the issue is expected to exacerbate in the 'Future Internet', as it is expected to house billions of services, with thousands offering the same functionality. In this context, maintaining an operational and solid set of Web service configurations will be a challenging task. Moreover, a centralized solution for Web service composition in the Future Internet scenario would be another issue. In this paper, we present a technique inspired from ElectroMagnetism in physics to create an environment which facilitates the selection of a service from a set of similar services. The proposed model achieves service composition in a decentralized environment without involving a centralized orchestrator. To validate the proposed technique in-silico experiments were conducted whose results demonstrate good performance in terms of completion time and load balancing. Further, the proposed technique is validated in-house (within our Institute's Intranet and with real users) by deploying real Web services on decentralized nodes. The results obtained via simulation are verified through a prototype based on the proposed model. We present, discuss and compare the effectiveness of the proposed work in the results section.","PeriodicalId":215397,"journal":{"name":"2014 IEEE International Conference on Web Services","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124973767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The generalization is achieved by two techniques borrowed from Category Theory: 1) decomposition of a REST system into cohesive link and communication layers, and 2) uniform representation of resource interfaces and resource compositions as categorial links. Within this framework, we introduce three types of categorial links: basic, nested and concurrent, and we show that many domain tasks in hyperlink pipeline, call control and media workflows can be accomplished efficiently by these links.

Services can in turn be composed with the help of these participants. However, the composite structure, the subjective interpretation of trust demand, and the opportunistic connectivity make service composition a challenging task in S-MSN. In this paper, we propose a novel approach to enable trustworthy service evaluation and invocation during the process of composition. By analyzing dependency relationships, our approach can decentralizedly evaluate the trust degree of each service based on a lattice-based trust model to prevent data from being transmitted to untrustworthy counterparts. Besides, service consumers and vendors are able to specify their global and local constraints on the trust degree of service components on demand for more effective composition. Finally, by introducing acquaintances to the neighbors iteratively, social participants form a trust-aware acquaintance graph to forward invocation messages.","PeriodicalId":215397,"journal":{"name":"2014 IEEE International Conference on Web Services","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129915225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to improve the prediction accuracy of Collaborative filtering algorithms, various factors are taken into account (e.g., location factor, environment, etc.).

Actually, QoS performance of Web services is highly related to the service status and network environments which are variable against time. Thus, this paper proposes a time-aware collaborative filtering algorithm to predict the missing QoS values. To validate our algorithm, this paper conducts series of large-scale experiments based on a real-world Web service QoS dataset.
