This paper describes a business-oriented analysis environment facilitating analyses of coherent data from Data Warehouses (DWs) and Linked Open Data (LOD) datasets. Specifically, we present a multidimensional modeling solution, named Unified Cube, which provides a single, comprehensive representation of data from multiple sources. Unified Cubes include both concepts close to business terms and user-friendly graphical notations. An implementation framework is proposed to enable unified analyses of warehoused data and LOD. The feasibility of the proposed concepts is illustrated with examples based on real-world datasets.
本文描述了一个面向业务的分析环境,便于分析来自数据仓库(DWs)和链接开放数据(LOD)数据集的一致数据。具体来说,我们提出了一个多维建模解决方案,名为Unified Cube,它提供了来自多个数据源的数据的单一、全面的表示。统一多维数据集包括接近业务术语的概念和用户友好的图形符号。提出了一个实现框架,以实现对仓库数据和LOD的统一分析。基于真实世界数据集的实例说明了所提出概念的可行性。

This paper presents the high-level architecture (HLA) of the research project DEWI (dependable embedded wireless infrastructure). The objective of this HLA is to serve as a reference for the development of industrial wireless sensor and actuator networks (WSANs) based on the concept of the DEWI Bubble. The DEWI Bubble is defined here as a high-level abstraction of an industrial WSAN with enhanced interoperability (via standardized interfaces), technology reusability, and cross-domain development. This paper details the design criteria used to define the HLA and the organization of the infrastructure internal and external to the DEWI Bubble. The description includes the different perspectives, models or views of the architecture: the entity model, the layered model, and the functional view model (including an overview of interfaces). The HLA constitutes an extension of the ISO/IEC SNRA (sensor network reference architecture) towards the support of industrial applications. To improve interoperability with existing approaches the DEWI HLA also reuses some features from other standardized technologies and architectures. The HLA will allow networks with different industrial sensor technologies to exchange information between them or with external clients via standard interfaces, thus providing a consolidated access to sensor information of different domains. This is an important aspect for smart city applications, Big Data and internet-of-things (IoT).
本文介绍了可靠嵌入式无线基础设施(DEWI)研究项目的高级体系结构(HLA)。该HLA的目标是为基于DEWI气泡概念的工业无线传感器和执行器网络(wsan)的发展提供参考。DEWI泡泡在这里被定义为工业WSAN的高级抽象,具有增强的互操作性(通过标准化接口)、技术可重用性和跨域开发。本文详细介绍了用于定义HLA和DEWI气泡内部和外部基础设施组织的设计标准。描述包括体系结构的不同透视图、模型或视图:实体模型、分层模型和功能视图模型(包括接口的概述)。HLA构成了ISO/IEC SNRA(传感器网络参考架构)的扩展,以支持工业应用。为了提高与现有方法的互操作性,DEWI HLA还重用了其他标准化技术和体系结构的一些特性。HLA将允许具有不同工业传感器技术的网络通过标准接口在它们之间或与外部客户端交换信息,从而提供对不同领域传感器信息的统一访问。这是智慧城市应用、大数据和物联网(IoT)的一个重要方面。

Wireless technology is expanding to areas previously reluctant to the use of this type of technology. In the aeronautics industry, wireless has recently gained preference for on-board systems that conventionally used only cables. Recent interference and reliability studies with state-of-the-art standards suggest the feasibility of a relatively new research area that has been called wireless avionics intra-communications (WAICs). This paper presents a non-exhaustive survey of efforts in this emerging area. The objective is to identify topics, design issues, and synergies with other fields. The design of WAICs resembles some aspects of networks on ground, but it also adds some particular issues that remain to be addressed. This paper attempts to identify design issues of WAICs that range from physical-layer to application and security layers. Structure health monitoring, bus communications, control/sensing, and cable replacement, are examples of applications of WAICs.
无线技术正在向以前不愿使用这种技术的地区扩展。在航空工业中,无线技术最近获得了传统上只使用电缆的机载系统的青睐。最近采用最新标准进行的干扰和可靠性研究表明,无线航空电子内部通信(WAICs)是一个相对较新的研究领域。本文对这一新兴领域的努力进行了不详尽的调查。目标是确定主题、设计问题以及与其他领域的协同作用。WAICs的设计类似于地面网络的某些方面,但它也增加了一些有待解决的特殊问题。本文试图确定从物理层到应用层和安全层的waic的设计问题。结构健康监测、总线通信、控制/传感和电缆更换都是waic应用的示例。

Users need trusting in data managed by software applications that are part of Information Systems (IS), which supposes that organizations should assuring adequate levels of quality in data that are managed in their IS. Therefore, the fact that an IS can manage data with an adequate level of quality should be a basic requirement for all organizations. In order to reach this basic requirement some aspects and elements related with data quality (DQ) should be taken in account from the earliest stages of development of software applications, i.e. “data quality by design”. Since DQ is considered a multidimensional and largely context-dependent concept, managing all specific requirements is a complex task. The main goal of this paper is to introduce a specific methodology, which is aimed to identifying and eliciting DQ requirements coming from different viewpoints of users. These specific requirements will be used as normal requirements (both functional and non-functional) during the development of IS awareness of data quality.
用户需要信任由作为信息系统(IS)一部分的软件应用程序管理的数据,这假定组织应该确保在其IS中管理的数据具有足够的质量水平。因此,信息系统能够以适当的质量水平管理数据这一事实应该是所有组织的基本要求。为了达到这一基本要求,应该在软件应用程序开发的最初阶段就考虑到与数据质量有关的一些方面和元素,即“设计数据质量”。由于DQ被认为是一个多维的并且很大程度上依赖于上下文的概念,因此管理所有特定的需求是一项复杂的任务。本文的主要目标是介绍一种特定的方法,该方法旨在识别和引出来自用户不同观点的DQ需求。在开发IS数据质量意识的过程中,这些特定需求将作为正常需求(包括功能性和非功能性)使用。

Customizing content according to preferences of the user and the current context is a key issue in electronic media. Audio content has some advantages over written text and video. Yet, apart from music playlists, little previous work has been performed on customizing audio content, i.e. speech-music playlist generation. The presented work makes a number of recommendations for speech-music playlist generation based on the program of broadcast radio channels. Nearly twenty thousand hours of audio content of twenty broadcast radio channels from four countries have been analyzed. Speech, music and mixed blocks were recognized automatically. The resulting data was analyzed for general statistics over the three types of audio blocks, for typical transitions and also for weekly and daily patterns. The paper also draws conclusions for customized speech-music playlist generation.
根据用户的偏好和当前环境定制内容是电子媒体中的一个关键问题。音频内容比书面文本和视频有一些优势。然而,除了音乐播放列表之外,以前很少有人在定制音频内容,即语音音乐播放列表生成方面进行工作。本文提出了一些基于广播频道节目的语音音乐播放列表生成的建议。分析了来自4个国家的20个广播电台频道近2万小时的音频内容。语音,音乐和混合块被自动识别。结果数据被分析为三种类型音频块的一般统计数据,典型的过渡以及每周和每天的模式。本文还对定制语音音乐播放列表的生成进行了总结。

The rapid growth of Social Commerce (s-commerce) fuels the need for delivering better quality of services. The existence of C2C social commerce on Facebook and other social media networks requires the use of electronic service quality (e-SQ) instruments. The aim of this paper is to apply the existing e-SQ measures to the context of C2C s-commerce in Thailand. A pilot test study was conducted on Facebook users to test the applicability of the scale. The results revealed five service quality dimensions which could be useful to sellers (Facebook users) in Thailand. The Thai scale offers an aggregate measure of seller's service quality on Facebook. The conclusion of this study and future research are discussed.
社交商务(s-commerce)的快速发展推动了提供更高质量服务的需求。在Facebook和其他社交媒体网络上存在C2C社交商务需要使用电子服务质量(e-SQ)工具。本文的目的是将现有的e-SQ措施应用于泰国C2C s-commerce的背景下。对Facebook用户进行了一项试点测试研究,以测试该量表的适用性。结果揭示了五个服务质量维度,这些维度可能对泰国的卖家(Facebook用户)有用。泰国量表提供了Facebook卖家服务质量的综合衡量标准。最后对本文的研究结论和未来的研究方向进行了展望。

In XML databases, several works have dealt with changes of basic components of XML Schemas: element and attribute declarations, simple types, and complex type definitions. However, there is no work that has dealt with changes to advanced concepts of XML Schemas like XML namespaces, local/global qualified/unqualified declarations, and schema definition styles. In this paper, we deal with XML namespace evolution. To the best of our knowledge, we are the first to study such a topic (and in an environment that supports schema versioning). More precisely, we propose an approach for managing changes to XML namespaces defined in XML Schemas, and their effects on XML documents that are valid to these schemas, while keeping track of all XML schema and XML instance versions.
在XML数据库中,有几本著作处理了XML schema的基本组件的变化:元素和属性声明、简单类型和复杂类型定义。但是,没有任何工作处理XML schema的高级概念(如XML名称空间、局部/全局限定/不限定声明和模式定义样式)的更改。在本文中,我们处理XML名称空间的演变。据我们所知,我们是第一个研究这样一个主题的人(并且是在一个支持模式版本控制的环境中)。更准确地说,我们提出了一种方法,用于管理对XML schema中定义的XML名称空间的更改,以及这些更改对这些模式有效的XML文档的影响,同时跟踪所有XML模式和XML实例版本。

Nowadays the use of ICT and especially online teaching became common part of education. Also at our Faculty we have been using ICT for many years. The first online courses of German we created in 2003 and we have been continuously improving and developing them since that time. After several years of validation of courses that we created, we tried a small study, to demonstrate how effective the use of ICT in teaching is. The aim of research was to identify the relationship of students to new methods of teaching, how often they use ICT to study the German language and finally to determine with what level of knowledge of foreign languages students come from high schools and how their knowledge improves after one semester.
如今,信息通信技术的使用,特别是在线教学已成为教育的普遍组成部分。在我们学院,我们已经使用信息通信技术很多年了。我们在2003年创建了第一个在线德语课程,从那时起我们一直在不断改进和发展它们。在对我们创建的课程进行了几年的验证之后,我们尝试了一个小型研究,以证明在教学中使用信息通信技术是多么有效。研究的目的是确定学生与新教学方法的关系,他们使用ICT学习德语的频率,并最终确定高中学生的外语知识水平以及他们的知识在一个学期后如何提高。

Exploiting CoDe modeling for the optimization of OLAP queries 利用代码建模来优化OLAP查询

The visualization of big-data represents a hard challenge due to the sheer amount of information contained in data warehouses. Thus, the accuracy on data relationships in a representation becomes one of the most crucial aspects to perform business knowledge discovery. A tool that allows to model and visualize information relationships between data is CoDe, which by processing several queries on a data-mart, generates a visualization of such data. However on a large data warehouse, the computation of these queries increases the response time by the query complexity. A common approach to speed up data warehousing is precompute a set of materialized views, store in the warehouse and use them to compute the workload queries. In this paper, we define a process exploiting the CoDe modeling to determine the minimal number of required OLAP queries and to mitigate the problem of view selection, i.e., select the optimal set of materialized views. The results of an experiment on a real data warehouse show an improvement in the range of 62–98% with respect the approach that does not consider materialized views, and 5% wrt. an approach that exploits them.
由于数据仓库中包含了大量的信息,大数据的可视化是一项艰巨的挑战。因此,表示中数据关系的准确性成为执行业务知识发现的最关键方面之一。允许对数据之间的信息关系进行建模和可视化的工具是CoDe,它通过处理数据集市上的几个查询,生成这些数据的可视化。然而,在大型数据仓库中,这些查询的计算增加了查询复杂性的响应时间。加速数据仓库的一种常用方法是预先计算一组物化视图,存储在仓库中,并使用它们来计算工作负载查询。在本文中,我们定义了一个利用CoDe建模来确定所需OLAP查询的最小数量并减轻视图选择问题的过程,即选择最优的物化视图集。在真实数据仓库上的实验结果表明,与不考虑物化视图的方法相比,该方法的改进范围为62-98%,wrt为5%。一种利用它们的方法。

The results of an experiment on a real data warehouse show an improvement in the range of 62–98% with respect the approach that does not consider materialized views, and 5% wrt. an approach that exploits them.","PeriodicalId":146662,"journal":{"name":"2016 Eleventh International Conference on Digital Information Management (ICDIM)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123815267","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}

Virtual agents are artificial intelligent artifacts that mimic natural conversations with users. The media equation posits that human-agent interaction mirrors the social cues prevalent in human-to-human relationship. As such, personality adaptation-convergence (similarity-attraction) and divergence (complementary-attraction) in human-agent interaction have been explored, particularly in the context of e-commerce, robot and scenario-based simulation. The present work extends prior studies by investigating personality adaptation in learner-agent interaction with respect to a virtual learning system. Pursuant to this goal, an introverted and an extroverted pedagogical agent were developed, as operationalized through vocal and animation parameters, and were then assessed by forty introverted and forty extraverted learners in a 2 (agent personality type) X 2 (learner personality type) experiment. The results of this study provided clear evidences in support of the complementary-attraction principle; emotional and motivational aspects of learning were significantly enhanced when the pedagogical agent exhibited personality (extraversion type) that complemented the learner's own. Theoretical and practical implications are discussed in this paper.
虚拟代理是模拟与用户自然对话的人工智能产品。媒体等式认为,人与代理人的互动反映了人与人之间关系中普遍存在的社会线索。因此,人类-代理交互中的人格适应-收敛(相似-吸引)和分歧(互补-吸引)已经被探索,特别是在电子商务,机器人和基于场景的模拟的背景下。本研究通过对虚拟学习系统中学习者-代理交互中的人格适应进行研究,扩展了先前的研究。根据这一目标,我们开发了一个内向和外向的教学代理,并通过声音和动画参数进行操作,然后在2(代理人格类型)X 2(学习者人格类型)实验中由40名内向和40名外向学习者进行评估。本研究结果为互补吸引原理提供了明确的证据支持;当教学主体表现出与学习者自身相辅相成的性格(外向型)时,学习的情绪和动机方面显著增强。本文讨论了理论和实践意义。
