Security threats for Big Data 大数据的安全威胁
Tarannum Zaki, Md. Sami Uddin, Mahedi Hasan, M. Islam
The world is advancing towards technological evolution day by day resulting in an exponential rise in Data. This massive volume of Data has introduced the idea of Big Data, which has captured the attention of business and IT scholars as a blessing and a source of immense opportunities for large organizations. Securing this huge amount of data has become a great concern in the field of information and communication technology. In this paper, we have conducted two studies to observe the security threats for big data: (a) first study was carried out on Enron email dataset (that contains about half a million of emails) to investigate the security challenges of big data in the field of email communication; and (b) second study was carried out on 35 undergraduate students to observe how phishing email generation based on users' intention or behavior may break the security system. The study results showed that big data analysis helps phishers to understand the behavior or interest of email users that can help them (phisher or hackers) to generate the phishing sites/emails to create big data security threats.
世界每天都在向技术进化前进,导致数据呈指数级增长。海量的数据带来了大数据的概念,大数据已经引起了商业和IT学者的注意,并被视为大型组织的福音和巨大机会的来源。保护如此庞大的数据量已成为信息通信技术领域的一个重要问题。在本文中,我们通过两项研究来观察大数据的安全威胁:(a)第一项研究是在安然电子邮件数据集(包含约50万封电子邮件)上进行的,以研究大数据在电子邮件通信领域的安全挑战;(b)第二项研究对35名本科生进行了研究,观察基于用户意图或行为生成的钓鱼邮件如何破坏安全系统。研究结果表明,大数据分析可以帮助网络钓鱼者了解电子邮件用户的行为或兴趣,从而帮助他们(网络钓鱼者或黑客)生成网络钓鱼网站/电子邮件,以制造大数据安全威胁。

Factors influencing knowledge communication in Malaysian public sector 影响马来西亚公共部门知识传播的因素
Rohaizan Daud, N. A. Rahim, Roslina Ibrahim
In the Malaysian public sector, a group of Information Technology (IT) experts and decision makers is the mastermind of the future of Information Communication and Technology (ICT). Therefore, common understanding between the IT experts and the decision makers is imperative for a collaborative and comprehensive decision making. However, there are few studies that gauge the parties' potential in knowledge integration, especially in terms of communication. Hence, developing further understanding of the communication factors that influence the knowledge integration between IT experts and decision makers is essential. Literature analysis showed that four factors influence the knowledge communication conceptual model: sharer, knowledge, relationship, and institution. However, after examining the Malaysian public sector by using purposive sampling strategy, there is a need to enhance the factors by highlighting two new items: high-level thinking and type of knowledge. These additional factors would improve the comprehensive knowledge communication in organizations for the decision making process.
在马来西亚的公共部门,一群信息技术(IT)专家和决策者是信息通信和技术(ICT)未来的策划者。因此,IT专家和决策者之间的共同理解对于协作和综合决策是必不可少的。然而,很少有研究衡量各方在知识整合方面的潜力,特别是在沟通方面。因此,进一步了解影响IT专家和决策者之间知识集成的沟通因素是必要的。文献分析表明,影响知识传播概念模型的因素有四个:共享者、知识、关系和制度。然而,在使用有目的的抽样策略检查马来西亚公共部门后,需要通过突出两个新项目来增强因素:高层次思维和知识类型。这些额外的因素将改善组织中决策过程的全面知识交流。

Fuzzy cognitive maps based on text analysis for supporting strategic planning 基于文本分析的模糊认知地图支持战略规划
P. Hájek, Ondřej Procházka, P. Pachura
Strategy maps are attracting considerable interest in strategic planning due to their capacity to represent causal-effect relationships among the key concepts. Several studies have used expert estimates to quantify the relationships. However, these evolve dynamically and are context-specific. Therefore, there is a need to develop automatic knowledge acquisition systems. Here, the assumption was used that knowledge can be extracted from strategic documents in order to conduct a detailed analysis of causal strategic concepts. First, latent semantic analysis is employed to obtain an interpretable semantic model. Second, collocated causal concepts are used to model relationships among strategic concepts. This approach to generate fuzzy cognitive maps (FCMs) is semi-automatic, requiring theoretical background literature/domain experts to determine the direction of the causalities. The FCMs can subsequently be used to simulate the effects of strategic management and, thus, provide an effective decision support tool. Several innovation strategies of regions are used as a case study and it is demonstrated that the generated FCMs are consistent with expert opinions and fuzzy ANP method.
战略地图由于能够表示关键概念之间的因果关系,在战略规划方面引起了相当大的兴趣。有几项研究使用了专家的估计来量化这种关系。然而,这些都是动态发展的,并且是特定于上下文的。因此,有必要开发自动知识获取系统。在这里,假设可以从战略文件中提取知识,以便对因果战略概念进行详细分析。首先,利用潜在语义分析获得可解释的语义模型。其次,利用并列因果概念对战略概念之间的关系进行建模。这种生成模糊认知图(fcm)的方法是半自动的,需要理论背景文献/领域专家来确定因果关系的方向。fcm随后可用于模拟战略管理的效果,从而提供有效的决策支持工具。以不同地区的创新策略为例,结果表明所生成的fcm与专家意见和模糊ANP方法是一致的。

Do private and sexual pictures receive more likes on Instagram? 私密和色情照片在Instagram上获得更多点赞吗?
Hyanghee Park, Joonhwan Lee
Photos are useful means of disclosing and sharing one's emotions and ordinary life. By uploading personal photos in SNS, people tend to manage their relationships with friends and develop new relationships in SNS. Though users' behavior of showing private pictures is considered to be common, there is little research on what kind of contents attract people's attention and become popular in SNS. The aim of this study is to empirically examine what kind of private and personal pictures attract more likes on Instagram. Moreover, this paper aims to find a difference of pictures disclosed by different groups such as male, female, and celebrities. In conclusion, our results demonstrate that there is a difference among photos uploaded by different kinds of groups. Also, the more users show sexual pictures of themselves the more they tend to receive likes.
照片是表达和分享个人情感和日常生活的有用手段。通过在社交网络上传个人照片,人们倾向于在社交网络中管理自己与朋友的关系,并发展新的关系。虽然用户展示私人照片的行为被认为是很普遍的,但是关于什么样的内容会吸引人们的注意力并在SNS中流行起来的研究却很少。本研究的目的是实证检验什么样的私人和个人照片在Instagram上吸引更多的点赞。此外,本文旨在找出不同群体(如男性、女性和名人)所披露的图片的差异。综上所述,我们的研究结果表明,不同类型的群体上传的照片存在差异。此外,用户展示自己的性感照片越多,他们就越容易得到点赞。

Experiences of Building Information Modelling (BIM) adoption in various countries 各国采用建筑信息模型(BIM)的经验
N. Mustaffa, Rozana Mohamed Salleh, Hamizah Liyana Tajul Ariffin
Building Information Modelling (BIM) is identified as a key technology and process to improve productivity and increase integration across various disciplines throughout the construction value chain. Successful BIM implementation depends on continuous support from the different disciplines and especially the main role player which is the government. Thus, for a successful BIM implementation, there must be targeted BIM initiatives at national level to ensure wider adoption of BIM. Based on extensive literature reviews from such as reports, journal articles, international conference papers and materials available on the internet; this paper describes what are initiatives have been taken from the various countries around the world; namely USA, UK, Finland, Hong Kong and Singapore, which are known as earlier BIM adopters Through the findings for an excellent and operative implementation of BIM in the country, the public and private sectors should interrelate and collaborate to develop and establish salient policies; frameworks and guidelines; efficient technologies system in exchange information; and BIM standards contract for the implementation of BIM. These experiences may shed some light on the initiatives, strategies and action that must be put in place for BIM to be holistically implemented in Malaysia.
建筑信息模型(BIM)被认为是一项关键技术和过程,可以提高生产力,并增加整个建筑价值链中各个学科的整合。BIM的成功实施依赖于不同学科的持续支持,尤其是政府这一主要角色。因此,为了成功实施BIM,必须在国家层面上有针对性的BIM计划,以确保更广泛地采用BIM。基于广泛的文献综述,如报告、期刊文章、国际会议论文和互联网上可用的材料;本文描述了世界各国采取的举措;即美国、英国、芬兰、香港和新加坡,这些国家被认为是BIM的早期采用者,通过在该国出色和有效地实施BIM的发现,公共和私营部门应该相互联系和合作,制定和建立重要的政策;框架和准则;高效的信息交换技术体系;以及BIM标准合同,用于BIM的实施。这些经验可能会对BIM在马来西亚全面实施所必须采取的举措、策略和行动有所启发。

Cultural determinants of research community participation 研究社区参与的文化决定因素
Rabiah Eladwiah Abdul Rahim, N. Ali, J. Jais
Informal and formal communities play important roles in organisations including in higher education institutions. These communities provide platforms for knowledge sharing and creation among participated members and in turn lead to research innovation. In order to increase participation in research community, higher education institutions need to address important cultural elements that support their knowledge activities. However, lack of studies examining cultural determinants of research community participation which might impact the role of community as the facilitator of organizational learning. Based on review of literature, this paper proposes top management support for knowledge sharing, openness and structure as the factors that influence research community participation. The identification of these factors are taking into account the needs of these cultural antecedents for the growth of research communities in the context of higher education institutions. Finally, the contributions and future research are discussed.
非正式和正式社区在包括高等教育机构在内的组织中发挥着重要作用。这些社区为参与的成员之间的知识共享和创造提供了平台,从而导致了研究创新。为了增加对科研社区的参与,高等教育机构需要解决支持其知识活动的重要文化因素。然而,缺乏对研究社区参与的文化决定因素的研究,这可能影响社区作为组织学习促进者的作用。在文献综述的基础上,本文提出影响科研共同体参与的因素包括高层管理对知识共享、开放性和结构的支持。在确定这些因素时,要考虑到这些文化背景对高等教育机构中研究团体发展的需求。最后,对本文的研究成果和未来的研究方向进行了展望。

The relationship between management support and individual motivation for knowledge sharing practice 管理支持与个人知识共享动机的关系
A. Ali, P. Dominic
Knowledge sharing is a key process that influences individual and organizational performance. The significance of sharing knowledge is confirmed through enormous number of previous studies. However individuals are not always motivated to share their knowledge. There are different factors might encourage or hinder employees to engage in knowledge sharing. This study aims at investigating the impact of the management support of an organization on the individual motivation for knowledge sharing. The proposed model reflects the structure of the constructs under investigation. The study uses a sample of 157 respondents collected from the oil and gas sector. The data were collected through survey method using an online questionnaire. The measurements were analyzed using the reliability analysis to confirm their internal consistency. Furthermore, the correlation matrix was generated to check on the significance of the interrelationship and to ensure the nonexistence of collinearity issue among the model constructs. The study applies the Structural Equation Modeling (SEM) techniques to validate the model and test the proposed hypotheses. The findings show that there is a strong positive relationship between management support and individual motivation for knowledge sharing. Therefore, the organizational support from top and middle management motivate employees to share their knowledge and experience with each other.
知识共享是影响个人和组织绩效的关键过程。知识共享的重要性通过大量的前期研究得到了证实。然而,个人并不总是有动力去分享他们的知识。有不同的因素可能会鼓励或阻碍员工参与知识共享。本研究旨在探讨组织的管理支持对个人知识分享动机的影响。所提出的模型反映了所研究的构念的结构。该研究使用了来自石油和天然气行业的157名受访者的样本。数据采用在线问卷调查的方式收集。使用信度分析对测量结果进行分析,以确认其内部一致性。此外,生成相关矩阵以检验相互关系的显著性,并确保模型结构之间不存在共线性问题。本研究运用结构方程模型(SEM)技术对模型进行验证,并对提出的假设进行检验。研究结果表明,管理支持与个人知识共享动机之间存在显著的正相关关系。因此,来自高层和中层管理人员的组织支持激励员工相互分享他们的知识和经验。

Exploring public e-service sustainability: In the case of Malaysia 探索公共电子服务的可持续性:以马来西亚为例
H. Nawi, O. Ibrahim, Azizah Abdul Rahman
E-service enables citizens to interact and receive services from most government agencies which are convenient, dependable, and less costly. Due to high investment allocated by the government all around the world to implement the e-service initiatives, it is important to ensure that the public e-service is sustained and continues to evolve. This study aims to identify the elements and dimensions of the e-service sustainability and how it can influence its sustainability. A case study was conducted at the one of the government agency in Malaysia to explore the public e-service sustainability criteria as it is perceived as a role model of a successful e-service provider. Qualitative data collected through interviews, observations and document analysis were analyzed verbatim using thematic analysis. Two regulators, three implementers, two e-service providers, nine users and one representative from a non-profit organization were interviewed to get a better understanding of the public e-service sustainability. Three dimensions with seventeen elements emerged from the case study and were visualized through the public e-service model.
电子服务使公民能够与大多数政府机构互动并接受服务,这些服务方便、可靠且成本较低。由于世界各国政府为实施电子服务计划而投入大量资金,因此确保公共电子服务的持续发展至关重要。本研究旨在确定电子服务可持续性的要素和维度,以及它如何影响其可持续性。在马来西亚的一个政府机构进行了一个案例研究,以探讨公共电子服务的可持续性标准,因为它被认为是一个成功的电子服务提供商的榜样。通过访谈、观察和文献分析收集的定性数据采用专题分析逐字进行分析。我们访问了两名规管机构、三名实施者、两名电子服务提供者、九名用户和一名非牟利机构代表,以加深对公共电子服务可持续性的了解。从案例研究中产生了包含17个元素的三个维度,并通过公共电子服务模型可视化。

Forecasting Malaysian exchange rate using machine learning techniques based on commodities prices 使用基于商品价格的机器学习技术预测马来西亚汇率
S. Ramakrishnan, S. Butt, Muhammad Ali Chohan, Humara Ahmad
This article investigates the dynamic interactions between four commodities prices and the exchange rate for an emerging economy, Malaysia. The literature has identified a series of contradictory claims in the support and against the accurate prediction of the exchange rate. This article provides a new methodology to perform a comparative analysis of the three machine learning techniques, namely: Support Vector Machine, Neural Networks, and RandomForest. The experimental results demonstrate that the RandomForest is comparatively better than Support Vector Machine and Neural Networks, for accuracy and performance. This shows that the fluctuation in the Malaysian exchange rate can be evaluated accurately using RandomForest as compare to other techniques. Furthermore, this paper reveals that Malaysian specific commodities prices-crude oil, palm oil, rubber, and gold, are the strong dynamic parameters that influence Malaysian exchange rate. Hence, these results are beneficial for policy making, investment modeling, and corporate planning.
本文研究了新兴经济体马来西亚的四种商品价格和汇率之间的动态相互作用。文献已经确定了一系列相互矛盾的主张,支持和反对准确的汇率预测。本文提供了一种新的方法来对三种机器学习技术进行比较分析,即:支持向量机,神经网络和随机森林。实验结果表明,随机森林在准确率和性能上都优于支持向量机和神经网络。这表明,与其他技术相比,使用RandomForest可以准确地评估马来西亚汇率的波动。此外,本文揭示了马来西亚特定商品价格-原油,棕榈油,橡胶和黄金,是影响马来西亚汇率的强大动态参数。因此,这些结果对政策制定、投资建模和企业规划都是有益的。

Hence, these results are beneficial for policy making, investment modeling, and corporate planning.","PeriodicalId":384130,"journal":{"name":"2017 International Conference on Research and Innovation in Information Systems (ICRIIS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126444617","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}

Sentiment analysis of student feedback using machine learning and lexicon based approaches 使用机器学习和基于词典的方法对学生反馈进行情感分析
Zarmeen Nasim, Quratulain Rajput, Sajjad Haider
This paper presents a combination of machine learning and lexicon-based approaches for sentiment analysis of students feedback. The textual feedback, typically collected towards the end of a semester, provides useful insights into the overall teaching quality and suggests valuable ways for improving teaching methodology. The paper describes a sentiment analysis model trained using TF-IDF and lexicon-based features to analyze the sentiments expressed by students in their textual feedback. A comparative analysis is also conducted between the proposed model and other methods of sentiment analysis. The experimental results suggest that the proposed model performs better than other methods.
本文提出了一种结合机器学习和基于词典的方法来分析学生反馈的情感。文本反馈通常在学期结束时收集,提供了对整体教学质量的有用见解,并为改进教学方法提出了有价值的方法。本文描述了一个使用TF-IDF和基于词汇的特征训练的情感分析模型,用于分析学生在文本反馈中表达的情感。并将该模型与其他情感分析方法进行了对比分析。实验结果表明,该模型的性能优于其他方法。
