When there are a large number of web services in use, it is non-trivial to quickly find web services satisfying the given request. Furthermore, when no single web service satisfies the given request fully, one needs to “compose” multiple web services to fulfill the goal. It is important to have a wise decision on underlying web-service composition framework because the search space for such a composition problem is in general exponentially increasing. Furthermore, if semantic and QoS issues are concerned, the composition problems become easily intractable. Toward this problem, in this paper, we present WSPR* - Web-Service PlanneR augmented with A* algorithm (a Label Correcting variation algorithm) to compose web services effectively.
当使用大量web服务时,快速找到满足给定请求的web服务是非常重要的。此外,当没有单个web服务完全满足给定请求时,需要“组合”多个web服务来实现目标。对底层web服务组合框架做出明智的决策非常重要,因为针对此类组合问题的搜索空间通常呈指数级增长。此外,如果涉及语义和QoS问题,则组合问题很容易变得棘手。针对这一问题,本文提出了WSPR* - web - service PlanneR,增强了A*算法(一种标签纠错算法)来有效地组合web服务。

Time-BPMN
Pub Date : 2009-07-20 DOI: 10.1109/CEC.2009.71
D. Gagné, A. Trudel
We present Time-BPMN which is an extension to the current version of the Business Process Modeling Notation (BPMN). Time-BPMN captures the temporal perspective of business processes. This extension deals with the various temporal constraints and dependencies that may occur while characterizing real world business processes. Time-BPMN allows for the specification and depiction of temporal constraints and dependencies within a BPMN diagram. It not only extends, but also simplifies certain existing temporal BPMN constructs. With our extension, BPMN becomes expressive enough to account for a very large set of real world business processes that are time dependent.
我们提出Time-BPMN,它是对当前版本的业务流程建模符号(BPMN)的扩展。Time-BPMN捕获业务流程的时间透视图。此扩展处理在描述真实世界的业务流程时可能出现的各种临时约束和依赖关系。Time-BPMN允许规范和描述BPMN图中的时间约束和依赖关系。它不仅扩展,而且简化了某些现有的临时BPMN构造。通过我们的扩展,BPMN变得足够具有表现力,可以解释大量依赖于时间的实际业务流程。

In this paper our focus is on issues and challengesfaced in monitoring energy consumption in thedomestic sector and way forward to deal with thesechallenges. Implementing a sensor network to monitorenergy consumption of household appliances in ameaningful way requires sophisticated network design.Such network has to deal with large amount rawsensor data coming from multiple sources. Thechallenge is how to collect necessary data and store itfor producing intelligent advice on economical energyusage for household. One way of dealing with thischallenge is to have smart sensor devices embedded inhome appliances, however currently a vast majority ofdomestic appliances do not have even dumb sensordevices to enable access to their energy consumptiondata. In a typical home environment we can expectsensing devices with various capabilities ranging frompassive device to intelligent and proactive devices.Raw data streams received from these devices need tonormalised and represented in semanticallyequivalence manners.
在本文中,我们的重点是国内部门能源消耗监测面临的问题和挑战,以及应对这些挑战的方法。实现传感器网络以有意义的方式监测家用电器的能源消耗需要复杂的网络设计。这种网络必须处理来自多个来源的大量原始传感器数据。挑战在于如何收集和存储必要的数据,以便为家庭提供经济能源使用的智能建议。应对这一挑战的一种方法是在家用电器中嵌入智能传感器设备,然而目前绝大多数家用电器甚至没有智能传感器设备来访问其能耗数据。在典型的家庭环境中,我们可以期待具有各种功能的传感设备,从被动设备到智能和主动设备。从这些设备接收的原始数据流需要规范化,并以语义对等的方式表示。

MOVE: A Generic Service Composition Framework for Service Oriented Architectures MOVE:面向服务架构的通用服务组合框架
Pub Date : 2009-07-20 DOI: 10.1109/CEC.2009.56
A. Rainer, J. Dorn
One main requirement for virtual organizations are shortterm collaborations between business partners to provide efficient and individualized services to customers. The MOVE project targets at a methodology and a software framework to support such flexible collaborations based on process oriented design and communication by Web services. MOVEs framework supports the graphical design and verification of business processes, the execution and supervision of processes in transaction-oriented environment, and the dynamic composition and optimization of processes. A business process may be composed from a set of Web services, deployed itself as Web service and executed in the framework. The automated composition of processes from Web services is implemented with methods from AI-planning. We map Web service descriptions, domain knowledge and customer requests into PDDL, an input language of AI-planners. We show the performance of our program with one typical AI planning system and give some implementation details. Finally we conclude with some remarks about further research.
虚拟组织的一个主要需求是业务伙伴之间的短期协作,以便为客户提供高效和个性化的服务。MOVE项目的目标是一种方法和软件框架,以支持这种基于面向过程的设计和Web服务通信的灵活协作。MOVEs框架支持业务流程的图形化设计和验证、面向事务的环境中流程的执行和监督,以及流程的动态组合和优化。业务流程可以由一组Web服务组成,自身作为Web服务部署,并在框架中执行。来自Web服务的流程的自动组合是通过ai规划的方法实现的。我们将Web服务描述、领域知识和客户请求映射到PDDL(一种人工智能规划者的输入语言)中。我们用一个典型的人工智能规划系统展示了我们的程序的性能,并给出了一些实现细节。最后,对今后的研究进行了总结。

Collaborative Feature-Combination Recommender Exploiting Explicit and Implicit User Feedback 利用显性和隐性用户反馈的协同特征组合推荐
Pub Date : 2009-07-20 DOI: 10.1109/CEC.2009.84
M. Zanker, M. Jessenitschnig
Collaborative filtering (CF) is currently the most popular technique used in commercial recommender systems. Algorithms of this type derive personalized product propositions for customers by exploitingstatistics derived from vast amounts of transaction data.Traditionally, basic CF algorithms have exploited a single category of ratings despite the fact that on many platforms a variety of different forms of user feedback are available for personalization and recommendation. In this paper we explore a collaborative feature-combination algorithm that concurrently exploits multiple aspects of the user model like clickstream data, sales transactions and explicit user requirements to overcome some known shortcomingsof CF like the cold-start problem for new users. We validate our contribution by evaluating it against the standard user-to-user CF algorithm using a dataset from a commercial Web shop. Evaluation results indicate considerable improvements in terms of user coverageand accuracy.
协同过滤(CF)是目前商业推荐系统中最常用的技术。这种类型的算法通过利用从大量交易数据中获得的统计数据,为客户提供个性化的产品建议。传统上,基本的CF算法利用了单一类别的评分,尽管在许多平台上有各种不同形式的用户反馈可用于个性化和推荐。在本文中,我们探索了一种协同特征组合算法,该算法同时利用用户模型的多个方面,如点击流数据、销售交易和明确的用户需求,以克服CF的一些已知缺点,如新用户的冷启动问题。我们通过使用来自商业Web商店的数据集对标准的用户对用户CF算法进行评估来验证我们的贡献。评估结果表明,在用户覆盖率和准确性方面有相当大的改进。

Reputation systems have been popular in several online market places involving anonymous players as it can provide crucial information on the trustworthiness of an object or individual player to combat selfish and deceptive behaviors from peers. Individual feedbacks on the quality of past association are the fundamental building blocks of reputation systems. Careful consideration in aggregating feedbacks from different sources is in fact very important in computing a reliable value for trust worthiness to facilitate decision making in a social dilemma situation like that of online market places. In this paper we are considering a possible improvement to a reputation model like that of eBay, with our interest lying on investigating how the cooperativeness and population of cooperators would evolve if the weight of the feedback source was assigned on the basis of past association between players. We categorize the feedback source as direct source, gray source and opposition friendly source to define an aggregation method for trustworthiness assessment that considers applying a dynamically computed weight to each source of feedback. Our result shows that breaking feedback sources on the basis of acquaintance and assigning weight accordingly favors the evolution of cooperativeness in the player society as compared to models which do not classify the feedback sources. A genetic algorithm based spatial iterated prisoner’s dilemma (SIPD) environment has been used to simulate the experiments.
声誉系统在一些涉及匿名玩家的在线市场中很受欢迎,因为它可以提供关于对象或个人玩家可信度的关键信息,以打击同伴的自私和欺骗行为。个人对过去联系质量的反馈是声誉系统的基本组成部分。事实上,仔细考虑来自不同来源的反馈,对于计算可靠的信任价值非常重要,这有助于在像在线市场这样的社会困境中做出决策。在本文中,我们正在考虑对eBay这样的声誉模型进行可能的改进,我们的兴趣在于研究如果反馈源的权重是基于玩家之间过去的关联来分配的,那么合作者的合作程度和数量将如何演变。我们将反馈源分为直接源、灰色源和反对友好源,定义了一种考虑对每个反馈源应用动态计算权重的可信度评估聚合方法。我们的研究结果表明,与没有对反馈源进行分类的模型相比,在熟人的基础上打破反馈源并相应地分配权重有利于玩家社会合作性的进化。采用基于遗传算法的空间迭代囚徒困境(SIPD)环境对实验进行了模拟。

A Semantic Based Framework for Supporting Negotiation in Service Oriented Architectures 支持面向服务体系结构中协商的基于语义的框架
Pub Date : 2009-07-20 DOI: 10.1109/CEC.2009.17
M. Comuzzi, K. Kritikos, P. Plebani
Negotiation is required before invoking a service in order to identify how the invocation must occur in terms of functional and non-functional criteria. This process is possible when all the involved parties agree on the same negotiation protocol (e.g., bilateral negotiations). Considering a Service Oriented Architecture (SOA), this negotiation protocol cannot be predefined, but it must be selected by considering the negotiation capabilities of the involved services.In this work, we propose a semantic-based framework for supporting the negotiation in SOA. Specifically, the framework allows to express the negotiation capabilities of service requesters and providers and proposes a mechanism for discovering the negotiation protocols that can be enacted when a negotiation is required. To improve the flexibility of the framework, the concept of delegation is introduced to deal with the situation in which a party, that is not able to support the negotiation protocol, wants to participate in a negotiation. In this case, the negotiation can be fully or partially delegated to one or more other parties that, instead, are able to support the negotiation protocol.
在调用服务之前需要进行协商,以便根据功能和非功能标准确定调用必须如何发生。当所有相关方同意相同的谈判协议(例如,双边谈判)时,这一过程是可能的。考虑到面向服务的体系结构(Service Oriented Architecture, SOA),此协商协议不能预定义,但必须通过考虑所涉及服务的协商能力来选择它。在这项工作中,我们提出了一个基于语义的框架来支持SOA中的协商。具体来说,该框架允许表达服务请求者和提供者的协商能力,并提出了一种机制,用于发现在需要协商时可以制定的协商协议。为了提高框架的灵活性,引入了授权的概念,以处理无法支持谈判协议的一方希望参与谈判的情况。在这种情况下,可以将协商全部或部分委托给能够支持协商协议的一个或多个其他方。

A System for Web-Based Interactive Real-Time Data Visualization and Analysis 基于web的交互式实时数据可视化与分析系统
Pub Date : 2009-07-20 DOI: 10.1109/CEC.2009.26

The convergence of mashup and Service Oriented Architecture (SOA) enables the enterprise to deliver composite and situational applications by integrating information across internal and external sources. In this paper, we propose an approach that takes ideas from mashup and extend it to deliver real-time interactive visual analysis application on spatial-temporal datasets over the Internet. Four aspects of the approach are discussed: temporal data mashup based on continuous queries, template driven and materialized mashup view for providing personalized services, real-time data transmission using Web Service Notification (WSN), geo-visualization mashup for visual synthesis, presentation and analysis. A prototype system has been built up for supporting hydrologic information observation and analysis, such as flood prediction, inundated area estimation, etc. Our preliminary findings will be beneficial to others to create Business Intelligence (BI) mashups for real-time visualization and business logic analysis.
mashup和面向服务的体系结构(Service Oriented Architecture, SOA)的融合使企业能够通过集成内部和外部源的信息来交付复合应用程序和情景应用程序。在本文中,我们提出了一种从mashup中汲取思想并将其扩展到在互联网上提供时空数据集的实时交互式可视化分析应用程序的方法。本文讨论了该方法的四个方面:基于连续查询的时态数据mashup、用于提供个性化服务的模板驱动和实体化mashup视图、使用Web服务通知(WSN)的实时数据传输、用于可视化合成、表示和分析的地理可视化mashup。建立了支持洪水预报、淹没面积估算等水文信息观测与分析的原型系统。我们的初步发现将有助于其他人创建用于实时可视化和业务逻辑分析的商业智能(BI)混搭。

In this paper, we propose an approach that takes ideas from mashup and extend it to deliver real-time interactive visual analysis application on spatial-temporal datasets over the Internet. Four aspects of the approach are discussed: temporal data mashup based on continuous queries, template driven and materialized mashup view for providing personalized services, real-time data transmission using Web Service Notification (WSN), geo-visualization mashup for visual synthesis, presentation and analysis.
