Although web services themselves could automate some of the human work, existing systems tend to lack such an automation point of view in their designs. Furthermore, scalability, availability, reusability and customizability should be provided altogether for a platform to be practically useful. We propose an architecture which ultimately automates everything in using services as much as possible. Exploiting the increasing number of freely available software, our Kachako platform transfers services themselves in a data-centric way to arbitrary servers that users wish to use. While Kachako is primary provided as a large integrated system with graphical user interfaces, Kachako is designed in a modular way to adapt various demands of users by allowing partial reuse of modules. End users can use Kachako without any programming work, while programmers can customize the system or add their own services very easily.","PeriodicalId":226237,"journal":{"name":"2012 IEEE 19th International Conference on Web Services","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123002135","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}

Assembling Web services can be achieved through a standard called BPEL, which creates executable processes by orchestrating Web service invocations. The problem with BPEL is the inability to separate the process description from its realization. In other words, it requires a prior retrieval of concrete Web services, which can be very challenging regarding the issues surrounding service discovery and selection. In this paper, we propose to separate a BPEL process description from its realization. We extend the notion of abstract BPEL processes, in order to enable developers to describe their desired orchestrations abstractly without identifying concrete services, according to three levels: the needed functionality, the expected QoS levels, and the composition flow. Then, the abstract BPEL process is realized by a selection framework that automatically discovers, classifies, and selects suitable services to render the process executable. Backup services are also discovered to assure the continuity of the realized process.","PeriodicalId":226237,"journal":{"name":"2012 IEEE 19th International Conference on Web Services","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129193140","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 paradigm is a good fit for\"main-memory caching\" in which data storage and retrieval issues are relatively straight-forward. However, the caching requirements of certain workloads exceed even modern main-memory capacity. Although disk-offload offers the potential to overcome this capacity constraint, it poses a problem for the application-caching paradigm since application data may now be resident in either main-memory or on disk. In this paper, we therefore examine how disk-offload middleware can best support the application-caching paradigm for data-centric web-services. We present two disk-offload caching architectures, evaluate their performance, and draw conclusions as to their relative effectiveness.","PeriodicalId":226237,"journal":{"name":"2012 IEEE 19th International Conference on Web Services","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116025314","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}

More and more users are accustomed to regularly reading the latest news feeds and interacting with friends on these social websites. However, when the number of friends increases to a large extent, users will receive hundreds of messages in a day and may be overwhelmed by the information overload. To alleviate this problem, we propose a novel visualization technique for social news feeds summarization on social web services. The proposed system SocFeedViewer can produce an egocentric network graph based on the news feeds generated in an arbitrary period of time. This graph provides an overview of those who have generated news feeds during this time period. To enhance the reading experience, we incorporate community detection, connectivity analysis, and importance analysis into our system to make users capable of preferentially surfing news feeds that are more significant and interesting.","PeriodicalId":226237,"journal":{"name":"2012 IEEE 19th International Conference on Web Services","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127382103","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}

These applications automated successfully the important frequent cases such as purchases, but the code needed for handling exceptions such as cancellations and failures tend to grow to disproportionate size and complexity. These difficulties lead to non-automated and expensive solutions such as call centers, which resolve data inconsistency problems manually. In this paper we describe the WED-flow (work, event, and data-flow) approach, which provides transactional recovery through incremental evolution of exception handling, by combining the concepts of advanced transaction models, events, and data states. By carefully recording the detailed data states of each execution step, WED-flow composes backward and forward recovery mechanisms as reusable exception handling services to preserve the consistency of all databases involved in the application with well-defined correctness properties. A practical application of the automated recovery in WED-flow is the real-time recovery of failed cases for mission-critical applications and services.","PeriodicalId":226237,"journal":{"name":"2012 IEEE 19th International Conference on Web Services","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122142700","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 purpose is to leverage the potential of IT to improve business performance. This goal can be achieved by developing mechanisms to enhance the communication between business and IT. In the same track, its essential to apply methods to assure that IT investments are driven by the strategic goals and priorities of the company. Service-Oriented Architecture (SOA)is widely recognized as a technology that promotes IT alignment and business agility. However, strategic goals of firms have been frequently neglected when dealing with technical subjects such as web service selection and deployment. In this work, we propose a multiple criteria decision method based on the Analytic Hierarchy Process (AHP) that is able to accommodate in a single framework both the technical and the strategic requirements of web service deployment and selection. Our framework help IT managers to find the configuration that best translates the preferences of the customer and the priorities of the company.

We propose an approach where we map service qualities to a common probabilistic trust metric. Whereas current trust approaches estimate the trustworthiness of a composite service based on a fully observable and static setting, we propose a statistical approach built on expectation maximized over a finite mixture model. Our experiments show that our approach can dynamically punish or reward the constituents of composite services while making only partial observations.","PeriodicalId":226237,"journal":{"name":"2012 IEEE 19th International Conference on Web Services","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125704545","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}

Since the laws or regulations are always written with complex legal terms, it is not easy for information system designers to understand precisely such laws and regulations and adopt them directly in their designs. In this paper, we propose the method of formalizing the Australian Privacy Act into executable processes and the method of modeling business in a privacy-aware way. Thus, by executing the processes over the privacy-aware business models, the information system designers can easily check the compliance of their designs with the privacy laws or regulations. In addition, the executable formalization of the Privacy Act makes it more efficient for law enforcement officers to process privacy violation cases. As an example, the clauses NPP 1.3 and NPP 2.1(s) of Australia Privacy Act are formalized and executed over a retailer's privacy-aware business model. The execution shows the same result as the investigation performed by the law enforcement officers.","PeriodicalId":226237,"journal":{"name":"2012 IEEE 19th International Conference on Web Services","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134532219","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}
