However, this inefficiency is due to the fact that works adopting this trend, consider that the conceptual model or a physical data source is the own and best representative of data sources. All requests subject to operational production bases, which represent punctual needs, were hence always ignored. In this article we consider the history of these requests, in addition to the conceptual data model (CDM), in order to introduce a new approach for an automatic design of a multi-dimensional diagram. The CDM is first translated into a multivariate pattern. Then, it is refined by using the history of requests. Both design steps use graphs as a formalism to represent the data model decision-making.","PeriodicalId":231641,"journal":{"name":"2011 IEEE 8th International Conference on e-Business Engineering","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134549693","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}

{"title":"Managing Procurement Spend Using Advanced Compliance Analytics","authors":"Pawan Chowdhary, M. Ettl, Amit Dhurandhar, Soumyadip Ghosh, Gopikrishnan Maniachari, B. Graves, B. Schaefer, Yu Tang","doi":"10.1109/ICEBE.2011.57","DOIUrl":"https://doi.org/10.1109/ICEBE.2011.57","url":null,"abstract":"Often the processes for purchasing commodities and services within a business enterprise are centralized into a procurement organization. These purchases are often sourced from one or more suppliers, or vendors, based on contract terms and conditions (such as price, payment terms etc.), availability, and quality or legacy habit of purchasing service with known vendors. We have found that many organizations lack appropriate processes and disciplines to drive demand to preferred suppliers. Thus these enterprises are unable to leverage the value of the pre-negotiated contracts due to lack of process education, approval process steps or appropriate purchasing tools that could result in significant amounts of spending that would be considered not compliant (not being sourced through preferred suppliers). Depending upon the size of the organization, such transactions range from several million dollars to billions of dollars. Manually sifting or employing typical query tools to review large amounts of spend transaction data with multiple attributes to identify the level of non compliant spend and identify areas to take action is a daunting task. In this paper, we discuss a software solution for spend compliance analytics that includes measurements of cost savings due to increased compliance and identification of areas where spend tends to be non compliant. We have developed a web enabled advanced analytical solution called Compliance Analytics Tool (CAT) that embeds a two phase methodology for compliance management. In the first phase, we use advanced data mining techniques to segment a large amount of historical spend transactions to quickly identify promising areas of improvement, exploiting a multitude of purchasing attributes such as business unit, procurement category, suppliers, etc. The second phase employs portfolio optimization techniques to further focus on specific segments that provide maximum benefit based on desired compliance targets or available budget. We also discuss the solution architecture that integrates business analytics along with business intelligence tools, dashboards, and data warehousing.","PeriodicalId":231641,"journal":{"name":"2011 IEEE 8th International Conference on e-Business Engineering","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126529808","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}

While the stimulus has promoted the development of China's domestic market, it has resulted in serious problem of inflation. In her efforts to control the inflation, China's government has encouraged retailers to engage directly with goods producers to reduce the cost in the middle including distribution, transportation and other retailing cost. In this paper, we analyze the role of warehouse in this transition. We argue that warehouse could provide additional opportunities to tackle the inflation by linking the suppliers and consumers. The warehousing scheme is then introduced with risk analysis. Evaluation and potential adoption analysis is also conducted.","PeriodicalId":231641,"journal":{"name":"2011 IEEE 8th International Conference on e-Business Engineering","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133963595","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}

{"title":"CREST: Towards Fast Speculation of Straggler Tasks in MapReduce","authors":"Lei Lei, Tianyu Wo, Chunming Hu","doi":"10.1109/ICEBE.2011.37","DOIUrl":"https://doi.org/10.1109/ICEBE.2011.37","url":null,"abstract":"Data-Intensive Computing emerges as the fourth paradigm for modern scientific discoveries. MapReduce, a programming paradigm for large-scale data-parallel applications, is widely applied to web indexing, machine learning, and scientific simulations in industries as well as in academia. Recently, the virtualized \"utility computing\" environments, such as campus cloud, are becoming an important scenario to run MapReduce jobs. For a MapReduce job, the straggler tasks may dominate the response time and delay whole job. Various speculation schemes have been proposed to alleviate such problem, however, most of them implicitly assume that the time cost for data movement on launching speculative map tasks is trivial, which does not always hold for the virtualized Hadoop clusters in a campus cloud. In this paper, we propose a novel approach, CREST(Combination Re-Execution Scheduling Technology), which can achieve the optimal running time for speculative map tasks and decrease the response time of MapReduce jobs. The main idea is that re-executing a combination of tasks on a group of computing nodes may progress faster than directly speculating the straggler task on target node, due to data locality. The evaluation validates our approach and demonstrates that CREST can reduce the running time of a speculative map task by 70% with best cases and 50% on average, comparing with LATE.","PeriodicalId":231641,"journal":{"name":"2011 IEEE 8th International Conference on e-Business Engineering","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131510775","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 this paper, we present a novel web-of-trust-based personalized seller recommendation algorithm. Starting from transaction-related data and trading relationship, the buyer-buyer web-of-trust and buyer-seller web-of-trust for recommendation and related concepts are formally defined. The method of constructing the web-of-trust is discussed. The algorithms computing direct trust and recommending trust between buyers based on web-of-trust are presented, and the algorithm for computing direct trust of the buyer in the seller is described. Aiming at the needs of the user intending to buy a specific product, the web-of-trust-based personalized seller recommendation algorithm is proposed, which can be used to find the most trustworthy seller selling the specified product for the buyer. The algorithms for computing direct trust of the recommender in target seller and comprehensive trust of the requester in target seller are designed. Using an example, the process of generating seller recommendation is described, and the recommendation results are analyzed.","PeriodicalId":231641,"journal":{"name":"2011 IEEE 8th International Conference on e-Business Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131005399","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}

Although the information technology is advanced as well, the advantage of leveraging information technology on disaster prevention and recovery has not been effectively utilized yet. Undoubtedly, natural disasters have already exposed the deficiency of existing emergency communications system. In this system, disaster warning subsystem is built upon conventional TV and radio broadcasting, while the rescue mission relied on basic GSM and satellite communications. These traditional technologies can not satisfy the critical timing requirements of disaster warning and emergency medical service. In this paper, we describe an efficient and flexible methodology to develop emergency communications system in next generation mobile networks.

With ever growing use of computing platforms (i.e. mobile phones, tablets and embedded devices, etc.) the potential for compromising the security and privacy of an individual is increased. The Trusted Platform Module is restricted to integrity measurement and cryptographic operations, which is crucial in its own right. On the contrary, smart cards provide a general-purpose execution environment, but traditionally they are under a centralised control, which if extended to the other computing platforms may not be appropriate. Therefore, in this paper we analyse the rationale for a general-purpose cross-platform user centric tamper-resistant device based on the smart card architecture, its applications in different computing environments, along with the ownership management framework.","PeriodicalId":231641,"journal":{"name":"2011 IEEE 8th International Conference on e-Business Engineering","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125486116","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}

On the other hand, the number of teachers in schools or universities is growing slowly. As a result, instructional problems have emerged due to lack of sufficient support to learners in their e-learning process. Collaborative learning is suggested as a solution to this problem. However, current collaborative learning has focused on teamwork or group discussion without sufficient support to each individual. This paper presents a new model for collaborative e-learning called Collaborative Cloud, in which knowledge modelling and market economic mechanism are utilized to optimize the collaborative use of e-learning resources including teachers, students, and artifacts in collaboration. To implement the approach, cloud computing and electronic commerce are applied to connect learners and coordinate the resources in e-learning in a more effective way.","PeriodicalId":231641,"journal":{"name":"2011 IEEE 8th International Conference on e-Business Engineering","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121609883","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}
