An empirical study on the effect of the order of applying software refactoring 软件重构应用顺序影响的实证研究
Yahya Khrishe, M. Alshayeb
Refactoring has been widely used to improve software design. Refactoring is applied when a bad smell is detected. Several bad smells might be present in the code. In this paper, we conduct an empirical study to find if the order of applying refactoring has any impact on the quality of the final code. We run six experiments by applying three refactoring methods in different orders and evaluate the quality of the code using software metrics at the end of each refactoring sequence. Our experiments results show that that applying refactoring in different order provides different impact on the final code.
重构被广泛用于改进软件设计。当检测到不良气味时应用重构。代码中可能存在一些不好的气味。在本文中,我们进行了一项实证研究,以发现应用重构的顺序是否对最终代码的质量有任何影响。我们通过应用三种不同顺序的重构方法进行了六个实验,并在每个重构序列结束时使用软件度量来评估代码的质量。我们的实验结果表明,按不同顺序进行重构对最终代码的影响是不同的。

How Jordanian e-Government websites respond to the needs of people with disabilities 约旦的电子政府网站如何回应残障人士的需要
Abeer F. Al-bataineh, S. Mustafa
Many Governments have realized the importance of information and communication technology (ICT) to improve the delivery of information and services to citizens and business. The fame of internet use, and the wide spread of mobile and portable means made the access to the governmental services easy and reachable at any time for a wide sector of citizens. People with disabilities have all the right to benefit from the e-services provided by the governmental websites equally with other citizens. To do so e-government websites must conform with the Web Content Accessibility Guidelines (WCAG). This paper was undertaken with three main purposes in mind, First: identifying the accessibility level of Jordanian e-Government websites in conformance with web content accessibility Guidelines (WCAG 1.0) at three level of priority, Second: assessing the efforts that have been devoted by the e-government websites to improve accessibility of Jordanian citizens with disability by comparing the recent results with our own study held in 2008. And finally, comparing Jordanian e-government accessibility results with another country (i.e. Dubai's e-government). The results indicate that the majority of Jordanian e-government websites fail to meet the minimum W3C accessibility conformance level. on the other hand many considerable improvements have taken place during the past 8 years. More than 65% of the errors had been eliminated. In comparison with Dubai's study, Jordanian e-Government websites score better in term of the average number of errors per page for priority1 and priority3 and approximate average number of errors per page for priority3.
许多政府已经认识到信息和通信技术在改善向公民和企业提供信息和服务方面的重要性。互联网使用的名声,以及移动和便携式设备的广泛普及,使得广泛的公民可以随时方便地获得政府服务。残障人士有权与其他公民一样,享受政府网站提供的电子服务。要做到这一点,电子政府网站必须遵守《无障碍网页内容指引》(WCAG)。本文主要有三个目的,第一:确定约旦电子政务网站的可访问性水平,以符合web内容可访问性指南(WCAG 1.0)的三个优先级;第二:通过将最近的结果与我们在2008年进行的研究进行比较,评估电子政务网站为改善约旦残疾公民的可访问性所做的努力。最后,将约旦的电子政务可访问性结果与另一个国家(即迪拜的电子政务)进行比较。结果表明,大多数约旦电子政务网站未能达到最低的W3C可访问性一致性水平。另一方面,在过去的8年里发生了许多显著的进步。超过65%的错误被消除了。与迪拜的研究相比,约旦的电子政务网站在优先级1和优先级3的平均每页错误数量以及优先级3的平均每页错误数量方面得分更高。

Holy Qur'an speech recognition system distinguishing the type of recitation 识别古兰经诵读类型的语音识别系统
B. Yousfi, A. Zeki
The act of reading Qur'an and pronouncing its sound dwells on the type of recitation. These are referring to the recitation of Warsh or the recitation of Hafss. It's very important to recognise the type of recitations, especially with the diversity and the spread of Qira'at in the world. This research presents a speech recognition system that distinguishes between the different types of the Qur'an recitation. The aim here is to design and developed a speech recognition for recitation of the Holy Qur'an for detecting the types of recitations and correction of fundamental and general errors. Although, there are several analysers that have been examined for error corrections, unfortunately, these analysers were not suitable for the act of recitation of the Holy Qur'an. Thus, the proposed system will be capable to recognize, identify and point out any mismatch. An experiment among student recitation with the recitation made by the expert teachers stored in a database has been done. Mel-Frequency Cepstral Coefficient (MFCC) for feature extraction and Hidden Markov Models (HMM) for feature classification are used.
诵读《古兰经》和诵读《古兰经》的行为,属于诵读的类型。这些指的是沃什的背诵或哈夫斯的背诵。认识到诵读的类型是非常重要的,尤其是考虑到Qira'at在世界上的多样性和传播。本研究提出了一种语音识别系统,可以区分不同类型的古兰经背诵。本文的目的是设计和开发一种诵读《古兰经》的语音识别系统,以检测诵读的类型并纠正基本和一般错误。虽然,有几个分析仪已经检查了错误纠正,不幸的是,这些分析仪不适合背诵神圣的古兰经。因此,所建议的系统将能够识别,识别和指出任何不匹配。在学生背诵实验中,将专家教师的背诵内容存储在数据库中。使用Mel-Frequency倒谱系数(MFCC)进行特征提取,使用隐马尔可夫模型(HMM)进行特征分类。

Investigating employees' understanding of the concept of privacy for the open Government initiative 调查雇员对“公开政府”私隐概念的理解
Nurul Amin Badrul, Karsten Øster Lundqvist, Patrick Parslow, S. Williams
Open government aims to improve the relationship between the government and citizens. In a shift from e-Government 2.0, open government provides openness of information and openness of interactions with the public. However, these opportunities pose privacy challenges in the implementation of open government. In order to address these privacy challenges, it is important to explore public employees' understanding of personal information and privacy concepts in general. This paper reports the preliminary results of a qualitative approach to explore Malaysian public service employees' understanding of personal information and privacy. Findings of this study indicate that employees have difficulties in explaining personal information and privacy.

A supervised approach for multi-label classification of Arabic news articles 阿拉伯语新闻文章多标签分类的监督方法
M. Shehab, Omar Badarneh, M. Al-Ayyoub, Y. Jararweh
Multi-label classification of textual data is an important problem with the growing size of available data and the increasing difficulties in assigning a single label to each piece of text. Examples range from news articles to emails. Most of the existing works consider English text. This work focuses on multi-label classification of Arabic articles. After dataset collection, three multi-label classifiers are considered (DT, RF and KNN). The results show a superiority of DT over the other two classifiers.
随着可用数据规模的不断增长和为每段文本分配单个标签的难度越来越大,文本数据的多标签分类成为一个重要问题。例子从新闻文章到电子邮件都有。现有的作品大多以英文文本为主。本工作的重点是阿拉伯语文章的多标签分类。数据集收集后,考虑三种多标签分类器(DT, RF和KNN)。结果表明,DT分类器优于其他两种分类器。

Emotion estimation from EEG signals during listening to Quran using PSD features 基于PSD特征的古兰经听者脑电信号情绪估计
M. Alsolamy, A. Fattouh
Emotions play an important role in our thinking and behavior and hence contribute in shaping up of our personality. Many theoretical and experimental researches have been conducted to recognize the emotions from verbal or non-verbal behaviors. It is well known that the electroencephalogram (EEG) signals contain rich information about the activities of the brain and they can reliably enable us to estimate the emotions if they are properly interpreted. In this paper, we propose a model to discriminate the emotional state of a person by analyzing his brain signals recorded during listening to the Quran and using a machine learning approach. It is assumed that listening to the Quran brings reverence, and hence two types of emotions emerge which are distinguished as happy and unhappy. In our analysis, we used the Power Spectral Density (PSD) of different bands as features and the Support Vector Machine (SVM) as a classifier. Experiments were conducted by 14 participants and they gave a classification accuracy rate 85.86%.
情绪在我们的思想和行为中扮演着重要的角色,因此有助于塑造我们的个性。从语言和非语言行为中识别情绪已经进行了许多理论和实验研究。众所周知,脑电图(EEG)信号包含了大脑活动的丰富信息,如果正确解读,它们可以可靠地使我们估计情绪。在本文中,我们提出了一个模型,通过分析一个人在听古兰经时记录的大脑信号,并使用机器学习方法来区分一个人的情绪状态。人们认为听《古兰经》会带来敬畏,因此出现了两种情绪,分别是快乐和不快乐。在我们的分析中,我们使用不同波段的功率谱密度(PSD)作为特征,支持向量机(SVM)作为分类器。14名参与者进行了实验,分类准确率为85.86%。

QoS based approach for LTE-WiFi handover 基于QoS的LTE-WiFi切换方法
Jumana Bukhari, N. Akkari
Nowadays, the current trend is to integrate WiFi with Long Term Evolution (LTE) networks in order to meet the growing demand for huge amounts of data traffic and provide ubiquitous coverage. Seamless mobility between heterogeneous networks with the required Quality of Services (QoS) provisioning for Mobile Terminals (MTs) is one of the most challenging issues while considering LTE-WiFi integration. Several studies reported in the literature have addressed the vertical handover (VHO) challenges between the two access networks. However, none of these approaches provides the MTs with the required QoS without adding a new entity or increasing the signaling cost. Thus, this paper proposes a VHO decision algorithm between LTE-WiFi heterogeneous networks. A performance study is conducted which compares the proposed approach with the WiFi First (WF) approach. Results show that the proposed approach can support QoS and reduce Wi-Fi blocking probability without adding any new entities to the infrastructure or increasing signaling costs. Also, the proposed approach outperforms existing solutions in terms of delay and signaling costs, while providing the MTs with the required QoS.
目前的趋势是将WiFi与LTE (Long Term Evolution,长期演进)网络相结合,以满足日益增长的海量数据流量需求,并提供无处不在的覆盖。在考虑LTE-WiFi集成时,异构网络之间的无缝移动性以及为移动终端提供所需的服务质量(QoS)是最具挑战性的问题之一。文献报道的一些研究已经解决了两个接入网之间的垂直切换(VHO)挑战。然而,这些方法都不能在不添加新实体或增加信令成本的情况下为mt提供所需的QoS。为此,本文提出了一种LTE-WiFi异构网络间的VHO决策算法。进行了性能研究,将所提出的方法与WiFi优先(WF)方法进行了比较。结果表明,该方法在不增加任何新的实体或增加信令成本的情况下,能够支持QoS并降低Wi-Fi阻塞概率。此外,所提出的方法在延迟和信令成本方面优于现有的解决方案,同时为mt提供所需的QoS。

A twitter sentiment analysis for cloud providers: A case study of Azure vs. AWS 针对云提供商的twitter情绪分析:Azure与AWS的案例研究
Laila M. Qaisi, Ibrahim Aljarah
The rapid revolution of Social Network Sites (SNS) around the globe is presenting wide range of data that can be used in studies of sentiment analysis about certain products, brands, services... etc. In addition, cloud computing fields had been one of the most interesting fields in research studies. In this paper, we used the sentiment analysis of top leading cloud service providers namely; Amazon and Microsoft Azure to analyse their customers' opinions and reviews. To do that, two datasets are extracted which are consisting of tweets that had either organizations' names or cloud names. We study, and analyze the way customers think about them. In this regard, many organizations tend to find out what do customers think or tweet about their products in order to effectively plan marketing campaigns and try to gain the positive impact of Word-of-Mouth. Results are analyzed and explained in details in term of polarity and emotions classifications to show the impact of sentiment analysis to support organizations decisions. We can note from the emotions classification results that, “joy” category is better for Microsoft Azure comparing to Amazon, The “sadness” percentage is larger for Amazon comparing to Microsoft Azure. Furthermore, we can note from the polarity classification that Microsoft Azure has 65% positive tweets compared 45% for Amazon. In addition, the results show that Amazon has 50% negative polarity compared 25% for Microsoft Azure.
社交网站(SNS)在全球范围内的快速革命提供了广泛的数据,可用于研究某些产品,品牌,服务的情感分析……等。此外,云计算领域一直是研究中最有趣的领域之一。在本文中,我们使用了顶级领先云服务提供商的情感分析,即;亚马逊和微软Azure来分析客户的意见和评论。要做到这一点,需要提取两个数据集,这些数据集由具有组织名称或云名称的tweet组成。我们研究和分析顾客对他们的看法。在这方面,许多组织倾向于找出顾客对他们的产品的想法或微博,以便有效地计划营销活动,并试图获得口碑的积极影响。在极性和情绪分类方面对结果进行了详细的分析和解释,以显示情绪分析对支持组织决策的影响。我们可以从情绪分类结果中注意到,与Amazon相比,Microsoft Azure的“快乐”类别更适合于Amazon,而与Microsoft Azure相比,Amazon的“悲伤”类别的百分比更大。此外,我们可以从极性分类中注意到,微软Azure有65%的正面推文,而亚马逊只有45%。此外,结果显示,亚马逊的负极性为50%,而微软Azure为25%。

Interest management through policy programming language 通过策略编程语言进行利益管理
Suzana Ahmad, S. Z. Abidin, N. Omar
Managing interest in collaborative data sharing involves determining interest of both owner and other parties. Interest management method is bound to information such as user request, location, history, preferences and data policies. Considering other researchers' works, managing data interest of sharing for its' constitutional adhered policy are rarely done in computerize manner. With attention that data shared are constituted with policy implicitly or explicitly, this paper proposes an automatic design of data policy via policy programming language in order to handle interest management. The study starts by analyzing secondary data through massive literature reviews. Two pertinent issues on interest management and data policy are explored, analyzed and summarized. Based on the research gap found in these analyses, an interest management for automated data policy is designed. As a case study, a new set of programming constructs are implemented and embedded into an existing collaborative language called JACIE (Java-based Authoring language for Collaborative Interactive Environments) that acts as a policy programming language. The results of this study conform that automated data policy is feasible and functioning well. Thus, this helps an interest manager to have flexible data policy in handling collaborative activities.
管理协作数据共享中的利益包括确定所有者和其他各方的利益。兴趣管理方法绑定了用户请求、位置、历史、偏好和数据策略等信息。考虑到其他研究人员的工作,很少以计算机化的方式对其“宪法遵守政策”的共享数据利益进行管理。考虑到共享数据是隐式或显式由策略构成的,本文提出了一种基于策略编程语言的数据策略自动设计,以实现兴趣管理。该研究首先通过大量文献综述分析二手数据。对利益管理和数据政策两个相关问题进行了探讨、分析和总结。基于这些分析中发现的研究差距,设计了一个自动化数据策略的兴趣管理。作为一个案例研究,我们实现了一组新的编程构造,并将其嵌入到一种称为JACIE(基于java的协作交互环境创作语言)的现有协作语言中,该语言充当策略编程语言。研究结果表明,自动化数据策略是可行且运行良好的。因此,这有助于兴趣管理人员在处理协作活动时拥有灵活的数据策略。
