Whilst there is enormous potential for applications that exploit this data in real-time, storing and querying it in real-time creates significant challenges. Traditional RDBMS systems are not sufficiently scalable, while typical cloud-based solutions such as map-reduce do not possess the capabilities required for real-time, spatial-data processing. Therefore, new approaches are needed. In this paper we explore the use of NoSQL technologies. These offer scalability, availability and fault tolerance, but -- as we show -- do not perform well with spatial data. Therefore, in this paper we address this challenge by enhancing existing spatial indexing structures with novel algorithms for inserting and searching spatial data. We have implemented this in a NoSQL solution (Antares), and evaluated it against two other NoSQL solutions, and a range of indexing structures: Kd-Tree, Quad Tree and Geohashing. The results show that Antares significantly outperforms the other approaches.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131045844","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 execute a process or a part of it, a business process owner selects and leases feasible resources while considering different constraints, e.g., Optimizing resource requirements and minimizing their costs. In this context, utilizing information about the process models or the dependencies between tasks can help the owner to better manage leased resources. In this paper, we propose a novel resource allocation technique based on the execution path of the process, used to assist the business process owner in efficiently leasing computing resources. The technique comprises three phases, namely process execution prediction, resource allocation and cost estimation. The first exploits the business process model metrics and attributes in order to predict the process execution and the requires resources, while the second utilizes this prediction for efficient allocation of the cloud resources. The final phase estimates and optimizes costs of leased resources by combining different pricing models offered by the provider.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124348728","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 solution can be found in Secure Multi-party Computation, a set of algorithms and protocols aimed at performing computations over private data sets in a secure way. In this contribution we describe the design and implementation of an airport slot trading platform based on secure computation. It allows different stakeholders to participate in auctions without having to publicly disclose their bid prices, thus ensuring the security of private (business related) information. Finally, several challenges, in terms of validation and expansion of the system, are presented and discussed.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"31 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128657185","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 query remains to be an interesting type of queries specially today with the appearance of many applications that need them. Today there are many databases that include scholarly data like DBLP, those databases though include information about papers, conferences, authors, and many other useful information, they don't correlate authors with similar interests or research directions. Nevertheless, the current explosion in the amount of data has driven the need for new techniques and technologies as traditional database techniques are no longer adequate to manage, store, and query those large amounts of data. Thus, the use of cloud emerged as a solution for several big data problems. Using clusters of commodity machines turn to be an optimal solution. Recently, there has been considerable interest in designing new algorithms using inverted index to efficiently answer different types of queries over big data. In this paper, we present a new technique for evaluating universal quantifier queries on recursive relation on large scholarly datasets using the popular MapReduce framework and inverted index. In addition, we present experimental results that show the performance of our proposed technique over the famous scholarly DBLP data-set.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125818191","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}

It proposes the paradigm of On-The-Fly Computing, which tackles emerging worldwide service markets. In these markets, service providers trade software, platform, and infrastructure as a service. Service requesters state requirements on services. To satisfy these requirements, the new role of brokers, who are (human) actors building service compositions on the fly, is introduced. Brokers have to specify service compositions formally and comprehensively using a domain-specific language (DSL), and to use service matching for the discovery of the constituent services available in the market. The broker's choice of the DSL and matching approaches influences her success of building compositions as distinctive properties of different service markets play a significant role. In this paper, we propose a new approach of engineering a situation-specific DSL by customizing a comprehensive, modular DSL and its matching for given service market properties. This enables the broker to create market-specific composition specifications and to perform market-specific service matching. As a result, the broker builds service compositions satisfying the requester's requirements more accurately. We evaluated the presented concepts using case studies in service markets for tourism and university management.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130652274","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}

It proposes a deterministic Proof of Data Possession (PDP) scheme based on interactive proof protocols. Our approach has several advantages. First, it supports public verifiability where the data owner delegates the verification process to another entity, thus releasing him from the burden of periodical verifications. Second, it allows the aggregation of several proofs and the verification of a subset of data files' proofs while providing an attractive communication overhead.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132211976","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}

Currently, most methods pursue a global reputation score essentially assuming that the value of a cloud service's reputation is the same for every consumer. However, depending on the expectations and needs of a consumer, there can be significant deviation of perceived reputation for the same cloud service. In this paper we propose a trust management framework that differentiates reputation for various user groups thus providing what we term local reputation. To achieve this we compute the similarity of consumers based a decision-tree model which is used to cluster feedback into localised scores. To refine the result, a time decay factor applicable to feedback is also to be considered. The simulation results illustrate that our approach is feasible and also effective for consumers to choose reputable cloud service.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115483077","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}
