If a group of customers raise personalized QoS constraints on a given service, the algorithm looks for a finite number of composition solutions to meet these requirements and realize maximum benefit. To pursue higher cost-effectiveness, we combine multiple individualized requirements together and find a limited number of composition solutions that jointly satisfy them. The algorithm adopts the recursive and greedy strategies to reduce the computation complexity. Mass requirements are ordered according to the \"potential benefit (PB)\", requirements with higher PB are handled earlier, and subsequent ones are handled based on previously obtained solutions using three heuristic policies. The MC4MR algorithm is further simplified as an OC4MR algorithm (to look for one solution for multiple customized requirements) and an OC4OR algorithm (to look for one solution for one requirement). Experiments are conducted to compare performance and cost-effectiveness between MC4MR and traditional approaches, and some factors that impact the quality of solutions are explored.","PeriodicalId":178841,"journal":{"name":"2012 IEEE Ninth International Conference on Services Computing","volume":"50 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":"121681799","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}

A Query Verification Method for Making Outsourced Databases Trustworthy 一种使外包数据库可信的查询验证方法

There needs a means for a data owner to verify the correctness and completeness of query results returned from these ODB services. The process is called query authentication. Existing ODB services do not provide such assurance to customers. This is mainly due to that most techniques in literature are expensive and limited in functionality. This paper proposes to use independent external observers for query result verification. The proposed method requires the ODB service to return a verification object (VO) for each query result set, as most existing methods do. Differing to existing methods, we propose a complement set based VO construction method. The cost of computing complement set based VO is low compared to hash tree based ones commonly seen in existing methods. The proposed method does not require the data owner or the ODB service provider to maintain complex authentication data structures, instead, the workload of data state tracking and VO validation can be distributed among a set of observers. Furthermore, the proposed VO construction method is capable of supporting multi-attribute queries. The method is implemented as a thin wrapper of an ODB service with the support of additional observer services. We evaluate the performance of the system in Amazon EC2 and examine its cost of achieving trustworthiness.","PeriodicalId":178841,"journal":{"name":"2012 IEEE Ninth International Conference on Services Computing","volume":"100 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":"132416813","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}

Case management systems are evolving to handle the growing demand for providing operational support to knowledge workers involved in these processes. While enabling flexibility in human actions is an integral part of these systems, this capability increases the potential for errors in case handling. We propose a new paradigm of case health aimed at providing knowledge workers and supervisors a case health service to continuously and objectively assess both the current state of a case instance and provide a prognosis for the future state of the instance. The case health service is composed of constituent services each of which provide case health indicators and can be combined in flexible ways to determine the overall health of an instance. We have implemented case health with respect to a simulated credit card dispute scenario modeled in IBM Case Manager and evaluated the utility of computing the case health of running instances of the credit card dispute scenario. Results indicate the utility of incorporating case health in a case management system in terms of early detection of undesired outcomes and abnormal execution patterns in running case instances.","PeriodicalId":178841,"journal":{"name":"2012 IEEE Ninth International Conference on Services Computing","volume":"51 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":"133333040","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}
