This is because these activities usually involve multiple stakeholders that include business domain experts, security experts, web service developers and IT operations teams, and there is no streamlined development environment to allow these stakeholders to work collaboratively on a business process. We have developed a cloud-based model-driven development and execution environment called SSC4Cloud to provide a shared business process modeling workspace and a business process execution environment. More specifically, with the shared modeling workspace, business process models can be developed, refined and shared. Within the shared execution environment, a business process model is translated into a WS-BPEL based executable model, which is then assigned for execution in a virtual machine container from a shared machine cluster. The common model execution environment supports both business process execution and enforcement of the security requirements attached to the business process models.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115048733","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 benefit of this paradigm is, on one hand to avoid the sensitive information leakage when individual devices failed or lost, on the other hand to make only the authorized users access and share the delegated information online anytime and anywhere. However, in this paradigm the critical problems to be resolved are to guarantee both the privacy of delegated individual information and the privacy of authorized users, and what is more important to afford the owners of communication devices to have high level of control and power to create their own particular access control policies. In this paper, we present an approach to implement the personalized access control at third service provider in a privacy preserving way. Our approach implements the critical problems above in this paradigm by using selective encryption, blind signature and the combination of role based access control and discretionary access control.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121813112","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}

Chou","doi":"10.1109/ICWS.2011.54","DOIUrl":"https://doi.org/10.1109/ICWS.2011.54","url":null,"abstract":"As REST architectural style gains popularity in the web service community, there is a growing concern and debate on how to design Restful web services (REST API) in a proper way. We attribute this problem to lack of a standard model and language to describe a REST API that respects all the REST constraints. As a result, many web services that claim to be REST API are not hypermedia driven as prescribed by REST. This situation may lead to REST APIs that are not as scalable, extensible, and interoperable as promised by REST. To address this issue, this paper proposes REST Chart as a model and language to design and describe REST API without violating the REST constraints. REST Chart models a REST API as a special type of Colored Petri Net whose topology defines the REST API and whose token markings define the representational state space of user agents using that API. We demonstrate REST Chart with an example REST API. We also show how REST Chart can support efficient content negotiation and reuse hybrid representations to broaden design choices. Furthermore, we argue that the REST constraints, such as hypermedia driven and statelessness, can either be enforced naturally or checked automatically in REST Chart.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121137612","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}

Such process knowledge enables service composition which integrates different services to implement business processes. In the current state of practice, business processes are primarily designed by experienced business analysts who have extensive process knowledge. It is challenging for novice business analysts and non-professional end-users to identify a complete set of services to orchestrate a well-defined business process due to the lack of process knowledge. In this paper, we propose an approach to extract process knowledge from existing commercial applications on the Web. Our approach uses a Web search engine to find websites containing process knowledge on the Internet. By analyzing the content and the structure of relevant websites, we extract the process knowledge from various websites and merge the process knowledge to generate an integrated ontology with rich process knowledge. We conduct a case study to compare our approach with a tool that extracts ontologies from textual sources. The result of the case study shows that our approach can extract process knowledge from online applications with higher precision and recall comparing to the ontology learning tool.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115268196","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 the recent past, several techniques have been developed and deployed to identify a composite service that conforms to the functional requirements and is also optimal with respect to the user-defined preferences over non-functional properties. However, these composition techniques are limited to using one formalism for specifying the required functionality, in short, the existing techniques cannot identify optimal (w.r.t. non-functional properties) composite services that are required to satisfy functional requirements described in multiple formalisms. We have previously proposed a meta-framework for service composition that involves decomposing the required functionality into a boolean combination of atomic requirements, which are expressed using different formalisms. This meta-framework supports the use of multiple formalisms and their corresponding composition algorithms within a single scenario. In this paper, we integrate support for unconditional preferences over nonfunctional requirements into this composition meta-framework. We show that for a large class of problems, local selection of preferred service(s) can yield the most preferred composite service that satisfies the desired functional requirements.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131444509","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}
