People have a tendency to mimic the actions of the larger group. Herd behavior is one of the most common phenomena in our daily life. Previous studies criticized that homogeneity of herd behavior and blind conformity will cause the bubble to burst. Crowd psychology plays an important role in service marketing. However, is it possible for service operation to thrive in service industry by manipulating the herd behavior? In this study, we proposed and validated that the Cascade-based service innovation (CSI) design which utilizes the attraction effect that highlights the service value and meaning interpretation enable service innovation opportunities. The cascade-based innovation design uses service meaning interpretation as the decoy and applies the attraction effect to drive the cascade-based service innovations. The result indicates that the CSI design could facilitate service providers to manipulate and reshape their service design to achieve sustainable development of service marketing. This study applied hybrid research methodologies that combine empirical research to examine the CSI design for fads operation and qualitative case study, and explore the criteria that enables service providers to operate and manipulate fads phenomenon successfully.
人们倾向于模仿更大群体的行为。羊群行为是我们日常生活中最常见的现象之一。以往的研究批评了从众行为的同质性和盲目从众会导致泡沫破裂。群体心理在服务营销中起着重要的作用。然而,通过操纵从众行为,服务经营是否有可能在服务业中茁壮成长?在本研究中,我们提出并验证了基于级联的服务创新(CSI)设计,该设计利用了突出服务价值的吸引效应和意义的解释,从而实现了服务创新的机会。层叠式创新设计以服务意义解释为诱饵,运用吸引效应驱动层叠式服务创新。结果表明,CSI设计有助于服务提供者操纵和重塑其服务设计,以实现服务营销的可持续发展。本研究采用实证研究与定性案例研究相结合的混合研究方法,对时尚运营CSI设计进行检验,探讨服务提供商成功运营和操纵时尚现象的标准。

Service Assurance Sustaining Enterprise Task Crowdsourcing Service 服务保证维持企业任务众包服务
Pub Date : 2016-06-01 DOI: 10.1109/SCC.2016.100
Chithralekha Balamurugan, K. K. Budhraja
Service Assured task execution is an exemplary need for Enterprise Task Crowdsourcing, even when crowdsourcing tasks on open and public crowdosourcing platforms, which are characteristic of non-committed and discretionary task execution by crowd workers. Service Assurance (SA) has broader semantics than SLA fulfillment in the context of enterprise task crowdsourcing, as explained in our previous work on Service Assurance Framework for Enterprise task crowdsourcing. The framework is designed for open crowd platforms and enables to map a given requester SLA to worker SA requirements and select crowd workers who evince high probability of SA requirement fulfillment. Even with these select crowd workers, it might not be possible to implicitly assume the sustenance of workers' expected SA (which is computed based on workers' prior task executions) in the day to day task executions on the Enterprise Requester tasks, owing to the unbinding task execution facilitated by the open crowd platforms. This might result in defaulting in requester SLA fulfillment, rendering the worker selection (by the framework) futile. Hence, in addition to selecting the required SA fulfilling workers, it is essential to employ suitable SA sustaining strategies in place for sustaining the SA expected of workers. The SA Sustaining Strategies and the Service Assurance Framework together constitute for the Service Assurance Sustaining Enterprise Task Crowdsourcing Service (SAS Service)for Enterprise Tasks, which is deliberated in this paper. The SAS Service's performance is validated using appropriate crowd experiments.
服务保证任务执行是企业任务众包的典型需求,即使在开放和公共众包平台上众包任务时也是如此,众包工作人员执行任务的特点是不承诺和自由裁量。服务保证(SA)在企业任务众包上下文中具有比SLA实现更广泛的语义,正如我们在之前关于企业任务众包的服务保证框架的工作中所解释的那样。该框架是为开放的人群平台设计的,它允许将给定的请求者SLA映射到工作人员SA需求,并选择具有高概率实现SA需求的人群工作人员。即使使用这些选择的人群工作者,也不可能隐式地假设在Enterprise Requester任务的日常任务执行中工人的预期SA(根据工人先前的任务执行计算)的维持,这是由于开放人群平台促进了非绑定任务执行。这可能导致默认的请求者SLA实现,使得(由框架)工作者选择无效。因此,除了选择所需的实现SA的员工外,还必须采用合适的SA维持策略来维持员工期望的SA。本文研究了服务保障持续型企业任务众包服务(SAS Service),即服务保障持续型企业任务众包服务。SAS服务的性能通过适当的人群实验得到验证。

Simulation is known to be an effective technique to understand and manage traffic in cities of developed countries. However, in developing countries, traffic management is lacking due to a wide diversity of vehicles on the road, their chaotic movement, little instrumentation to sense traffic state and limited funds to create IT and physical infrastructure to ameliorate the situation. Under these conditions, in this paper, we present our approach of using the Megaffic traffic simulator as a service to gain actionable insights for two use-cases and cities in India, a first. Our approach is general to be readily used in other use cases and cities, and our results give new insights: (a) using demographics data, traffic demand can be reduced if timings of government offices are altered in Delhi, (b) using a mobile company's Call Data Record (CDR) data to mine trajectories anonymously, one can take effective traffic actions while organizing events in Mumbai at local scale.
模拟被认为是一种有效的技术来了解和管理在发达国家的城市交通。然而,在发展中国家,由于道路上的车辆种类繁多,运动混乱,检测交通状态的仪器很少,用于改善这种状况的信息技术和物理基础设施的资金有限,交通管理缺乏。在这些条件下,在本文中,我们提出了使用Megaffic交通模拟器作为服务的方法,以获得针对印度两个用例和城市的可操作见解,这是第一次。我们的方法通常很容易用于其他用例和城市,我们的结果提供了新的见解:(a)使用人口统计数据,如果德里政府办公室的时间改变,交通需求可以减少;(b)使用移动公司的通话数据记录(CDR)数据匿名挖掘轨迹,人们可以在孟买组织当地规模的活动时采取有效的交通行动。

Multi-agent Reinforcement Learning for Service Composition 面向服务组合的多智能体强化学习
Pub Date : 2016-06-01 DOI: 10.1109/SCC.2016.108
Yu Lei, Philip S. Yu
This paper investigates the multi-agent cooperation problems in Web services domain. For Pareto-optimal Nash equilibrium, reinforcement learning algorithms are used to solve the coordination problem in cooperative environments. Most previous works study the deterministic gain of a state. However, in practical service environments, the gain may be nondeterministic due to unstable Quality of Service (QoS). To avoid local optimal solution, we use an improved update function. The experimental results show that proposed reinforcement learning algorithm outperforms other learning methods.
本文研究了Web服务领域中的多代理协作问题。针对帕累托最优纳什均衡,采用强化学习算法求解协作环境下的协调问题。以往的研究大多是研究状态的确定性增益。然而,在实际的服务环境中,由于服务质量(QoS)不稳定,增益可能是不确定的。为了避免局部最优解,我们使用了改进的更新函数。实验结果表明,本文提出的强化学习算法优于其他学习方法。

The realization of business process with services has gain more importance in the last decade. Several organizations are focusing nowadays in the modeling and execution of their business processes, seizing the advantages provided by both the BPMN 2.0 notation which allows these models to be executed, and the emergence of BPMS platforms which are able to execute business processes invoking internal and external services from partners and/or the cloud when needed. Although many lifecycle proposals exist to guide the definition and management of both business process and services, there is no clear relationship defined between them, i.e. how services should be defined and managed to support business processes. This is a key element that should be taken into account when implementing services for this kind of systems, in order to systematize the work and obtain better results. In this paper we present a service lifecycle to support business processes, which helps developing services for business process systems.
近十年来,用服务实现业务流程变得越来越重要。现在,一些组织正在关注其业务流程的建模和执行,抓住BPMN 2.0符号(允许执行这些模型)和BPMS平台(能够在需要时从合作伙伴和/或云调用内部和外部服务)所提供的优势。尽管存在许多生命周期建议来指导业务流程和服务的定义和管理,但它们之间没有明确的关系,即应该如何定义和管理服务以支持业务流程。这是为这类系统提供服务时应考虑到的一个关键因素,以便使工作系统化并取得更好的结果。在本文中,我们提出了一个支持业务流程的服务生命周期,它有助于为业务流程系统开发服务。

Latent Factor Model (LFM) is extensively used in dealing with user-item bipartite networks in service recommendation systems. To alleviate the limitations of LFM, this papers presents a novel unsupervised learning model, Latent Interest and Topic Mining model (LITM), to automatically mine the latent user interests and item topics from user-item bipartite networks. In particular, we introduce the motivation and objectives of this bipartite network based approach, and detail the model development and optimization process of the proposed LITM. This work not only provides an efficient method for latent user interest and item topic mining, but also highlights a new way to improve the accuracy of service recommendation. Experimental studies are performed and the results validate the LITM's efficiency in model training, and its ability to provide better service recommendation performance based on user-item bipartite networks are demonstrated.
潜在因素模型(Latent Factor Model, LFM)广泛应用于服务推荐系统中用户-物品二部网络的处理。为了缓解LFM的局限性,本文提出了一种新的无监督学习模型——潜在兴趣和主题挖掘模型(LITM),用于从用户-项目二部网络中自动挖掘潜在用户兴趣和项目主题。特别地,我们介绍了这种基于二部网络的方法的动机和目标,并详细介绍了所提出的LITM的模型开发和优化过程。这项工作不仅为潜在用户兴趣和项目主题挖掘提供了一种有效的方法,而且为提高服务推荐的准确性提供了一条新的途径。实验结果验证了LITM在模型训练方面的有效性,并证明了基于用户-物品二部网络的LITM能够提供更好的服务推荐性能。

With the rapid development of mobile internet and wireless network technologies, more and more people use the mobile app to call a taxicab to pick them up. Therefore, understanding the passengers' travel demand becomes crucial to improve the utilization of the taxicabs and reduce their cost. In this paper, based on spatio-temporal clustering, we propose a demand hotspots prediction framework to generate recommendation for taxi drivers. Specially, an adaptive prediction approach is presented to demand hotspots and their hotness, and then combing the driver's location and the hotness, top candidates are recommended and visually presented to drivers. Based on the dataset provided by CAR INC., the experiment shows that our approach gains a significant improvement in hotspots prediction and recommendation, with 15.21% improvement on average f-measure for prediction and 79.6% hit ratio for recommendation.

Traveling companions are object groups that move together in a period of time. In this paper, we introduce a special kind of traffic data stream, which is called Automatic Number Plate Recognition (ANPR) data. In order to quickly identify traveling companions on ANPR data stream, this paper proposes an analysis algorithm named COINCIDENT. Owing to the privacy and security of ANPR data stream, the algorithm is encapsulated as a data stream service. The main contributions include: 1) we consummate our previous stream data service model and design a traveling companion discovery service on the model. 2) the proposed COINCIDENT algorithm can instantly and continuously discover traveling companions on the live ANPR data stream. Final experiments show the effectiveness and efficiency of our developed service.

A QoS Evolutionary Method of Cloud Service Based on User Utility Model 基于用户实用新型的云服务QoS演化方法
Pub Date : 2016-06-01 DOI: 10.1109/SCC.2016.79
Yan Wang, Jiantao Zhou, Jing Liu, Tenghe Au, Xiaoyu Song
The quality-of-service (QoS) is a common focus which users and service providers pay close attention to at present. For service providers, it is one of their main targets to find the optimal QoS strategy based on user preferences. However, because of the fuzziness of user preferences and the complexity of service environment, searching an optimal service strategy becomes a difficult problem. In the paper, how the QoS affects a user's satisfaction is analyzed, and then a quantitative relationship between QoS and user satisfaction is built. Based on the relationship, a user utility model of cloud service is established. In order to maximize user utility, a QoS evolutionary algorithm based on user utility model is proposed. In the algorithm, some improvement is designed to balance the contradiction between search scope and search speed in the traditional genetic algorithm. It can be seen through the experiments that the QoS optimization strategy of cloud service output by the QoS evolutionary algorithm is consistent with the target user's preferences, which can effectively enhance the cost effectiveness of service resources.
服务质量(QoS)是当前用户和服务提供商共同关注的焦点。对于服务提供商来说,基于用户偏好找到最优的QoS策略是他们的主要目标之一。然而,由于用户偏好的模糊性和服务环境的复杂性,搜索最优服务策略成为一个难题。本文分析了服务质量对用户满意度的影响,建立了服务质量与用户满意度之间的定量关系。基于这种关系,建立了一种云服务用户实用新型。为了使用户效用最大化,提出了一种基于用户实用新型的QoS进化算法。该算法对传统遗传算法的搜索范围和搜索速度之间的矛盾进行了改进。通过实验可以看出,QoS进化算法对云服务输出的QoS优化策略与目标用户的偏好是一致的,可以有效地增强服务资源的成本效益。

It can be seen through the experiments that the QoS optimization strategy of cloud service output by the QoS evolutionary algorithm is consistent with the target user's preferences, which can effectively enhance the cost effectiveness of service resources.","PeriodicalId":115693,"journal":{"name":"2016 IEEE International Conference on Services Computing (SCC)","volume":"39 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133137271","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}

Log-based business operation analysis is getting more and more attention from enterprise decision makers. However, at the very first step of the analysis service, two primary obstacles are always encountered: how to process a wide variety of local event log formats and how to handle personally identifiable information weaved in an event log. Due to these obstacles, typical business analysts who do not have programming skills have lost business opportunities at the early stages. We propose a privacy-preserving data curation specification language, BELAS, for such analysts and present experimental results that show how most of a real-life event log could be processed in process analysis services.
基于日志的业务运营分析越来越受到企业决策者的重视。然而,在分析服务的第一步,总是会遇到两个主要障碍:如何处理各种各样的本地事件日志格式,以及如何处理编织在事件日志中的个人可识别信息。由于这些障碍,没有编程技能的典型业务分析人员在早期阶段就失去了业务机会。我们为这些分析人员提出了一种保护隐私的数据管理规范语言BELAS,并提供了实验结果,显示了如何在过程分析服务中处理大多数现实生活中的事件日志。
