This study explored the data mining tools role in cyber-risk management among Jordanian commercial banks listed on the Amman Stock Exchange. A standardized questionnaire was distributed to the information technology and bank risk management staff (n=139) in 13 commercial banks. There were significant effects of data mining tools in cyber-risk management on the discovery, dissemination, and participation of knowledge systems, and on opportunities to improve knowledge systems through the development of the environment for study and data retrieval systems. This study emphasizes the need to look for areas of improvement that would affect the efficiency of using data mining tools in the discovery, dissemination, and sharing of knowledge systems to manage cyber risks, as well as the need to combine data mining technology with to use their cognitive abilities and technical concepts with the necessary methods and tools to improve the bank's knowledge culture and to provide all necessary data stores and warehouses for the formation of new knowledge, which would help in the development of cyber risk management in Jordanian banks, which are listed on the Amman Stock Exchange.

On the Dynamics of Narratives of Crisis during Terror Attacks 论恐怖袭击中危机叙事的动态
Lisa Grobelscheg, Karolina Śliwa, Ema Kusen, Mark Strembeck
We present an analysis of the narratives that emerged on Twitter during four different terror attacks. To this end, we analyze a data-set consisting of more than five million Twitter messages. We use the structural topic model (STM) approach to automatically detect six narratives of crisis. Our findings indicate that i) Twitter users are highly engaged in the dissemination of operational and memorial narratives, ii) emotions and narratives directed towards authority accounts dominate the discourse regarding the entire event, iii) the presence of positive authority nodes (i.e. authority nodes who are predominantly perceived as being positive) directly impacts the type of a discourse and fuels hopeful memorial narratives to a larger extent than accusations and blaming.
我们对四次不同的恐怖袭击期间出现在Twitter上的叙述进行了分析。为此,我们分析了一个由500多万条Twitter消息组成的数据集。我们使用结构主题模型(STM)方法自动检测六种危机叙事。我们的研究结果表明,i) Twitter用户高度参与了操作性和纪念性叙事的传播,ii)针对权威账户的情绪和叙事主导了整个事件的话语,iii)积极权威节点(即主要被认为是积极的权威节点)的存在直接影响了话语的类型,并在更大程度上激发了充满希望的纪念叙事,而不是指责和指责。

Person Authentication using Visual Representations of Keyboard Typing Dynamics 使用键盘输入动态的可视化表示的人员认证
Ladislav Peška, Patrik Veselý, T. Skopal, Krisztián Búza
In this paper, we focus on the problem of user's authentication through typing dynamics patterns. We specifically focus on small-sized problems, where it is difficult to fully train corresponding machine (deep) learning algorithms from scratch. Instead, we propose a different approach based on the visualization of the typing patterns and subsequent usage of pre-trained feature extractors from the computer vision domain. We evaluated the approach on a publicly-available dataset and results indicate that this is a viable solution capable to improve over several baselines. Moreover, the proposed visual representation of the data contributes to the explainability of AI.
本文主要研究了通过输入动态模式实现用户身份认证的问题。我们特别关注小型问题,在这些问题上很难从头开始完全训练相应的机器(深度)学习算法。相反,我们提出了一种不同的方法,基于输入模式的可视化和随后使用来自计算机视觉领域的预训练特征提取器。我们在一个公开可用的数据集上评估了该方法,结果表明这是一个可行的解决方案,能够在几个基线上进行改进。此外,提出的数据可视化表示有助于人工智能的可解释性。

EI Integrated PR for Online Communication in Customer Loyalty: The Mediating Role of Artificial Intelligence EI整合公关对顾客忠诚度的影响:人工智能的中介作用
Riadh Jeljeli, Faycal Farhi, Saadia Anwar Pasha
Emotional Intelligence, when integrated into Public Relations, adds potential value to retail sector organizations. However, with the rise of ICT, these factors are further enriched by Artificial Intelligence as the organizations are more goal-oriented, adopting certain customer-centric approaches. This study also focused on the role of the Emotionally Intelligent Public Relation system in the United Arab Emirates benefiting from Artificial Intelligence integration. The primary focus remained on Artificial Intelligence, upgrading these Public Relations practices and improving customer loyalty. The researchers used a self-proposed conceptual model assessed using Structural Equation Modelling (SEM). Results revealed that Public Relations practices are significantly affecting Social Skills (p>. 020) and Empathy (.000) as primary components of Emotional Intelligence (EI). Besides, the effect of Social Skills on Empathy also remained significant (p> 045). On the other hand, Social Skills (p>. 000) have a significant effect on Customer Loyalty, which is significantly mediated by Artificial Intelligence (p>. 070). Thus, it is concluded that when Public Relations integrated with Emotional Intelligence are linked with Artificial Intelligence, positive, constructive outcomes are ensured. Particularly, in the retail sector, organizations integrating Artificial Intelligence provide the service as best matching the customers, adding more value to the services and product quality of the certain retailer, indicating the same patterns of consumer experiences leading to loyalty among them.
当情商被整合到公共关系中时,会为零售部门组织增加潜在价值。然而,随着信息通信技术的兴起,这些因素被人工智能进一步丰富,因为组织更加以目标为导向,采用某些以客户为中心的方法。本研究还关注了阿联酋从人工智能整合中受益的情商公关系统的作用。主要的焦点仍然是人工智能,升级这些公共关系实践并提高客户忠诚度。研究人员使用了一个自我提出的概念模型,使用结构方程模型(SEM)进行评估。结果显示,公共关系实践对社交技能有显著影响(p>。020)和共情(0.000)是情绪智力(EI)的主要组成部分。此外,社会技能对共情的影响也很显著(p> 045)。另一方面,社交技能(p>。000)对客户忠诚度有显著影响,人工智能显著调节了客户忠诚度(p>。070)。因此,我们得出结论,当与情商相结合的公共关系与人工智能相结合时,将确保积极的、建设性的结果。特别是在零售领域,整合人工智能的组织提供最匹配客户的服务,为特定零售商的服务和产品质量增加更多价值,表明相同的消费者体验模式导致他们之间的忠诚度。

Automated Question Answering based on Improved TF-IDF and Cosine Similarity 基于改进TF-IDF和余弦相似度的自动问答
Muzamil Ahmed, H. Khan, Saqib Iqbal, Q. Althebyan
This paper proposes an automated question answering system based on improved Term Frequency- Inverse Document Frequency (TF-IDF) and cosine similarity. The main purpose of this research study is to provide an effective question answering system that retrieves precise and relevant answers to the users' queries with high confidence. The existing studies in the relevant literature show that several techniques have been proposed for automatic question answering systems. The rule-based techniques depend on inference rules and take less time to respond to the user query. However, generations of pattern and inference rules are difficult as natural languages lack to follow a fixed pattern. The content-based similarity method pre-computes similarity with all the repository questions for a given query. In this research study, firstly all repository questions are pre-processed and a matrix using the improved TF -IDF model is generated. Then, we find the similarity of each user query with the matrix after query pre-processing. For the proposed approach, we remove stop-words and apply lemmatization and POS tagging techniques for pre-processing. The proposed framework is implemented using the standard datasets used in the existing studies. The empirical analysis-based results show that the systems adopting the proposed technique takes less than five seconds to respond to user queries with maximum similarity. The proposed framework attains up to 84% accuracy.
提出了一种基于改进词频-逆文档频率(TF-IDF)和余弦相似度的自动问答系统。本研究的主要目的是提供一个有效的问答系统,能够以高置信度检索用户查询的精确且相关的答案。现有的相关文献研究表明,已经提出了几种用于自动问答系统的技术。基于规则的技术依赖于推理规则,响应用户查询所需的时间更少。然而,模式和推理规则的生成是困难的,因为自然语言缺乏遵循固定的模式。基于内容的相似性方法预先计算给定查询与所有存储库问题的相似性。在本研究中,首先对所有知识库问题进行预处理,并使用改进的TF -IDF模型生成一个矩阵。然后,通过查询预处理,找出每个用户查询与矩阵的相似度。对于所提出的方法,我们去除停止词,并应用词序化和词性标注技术进行预处理。提出的框架是使用现有研究中使用的标准数据集来实现的。基于实证分析的结果表明,采用该技术的系统在5秒内就能以最大的相似度响应用户的查询。该框架的准确率高达84%。

Social Login Usage for Third-Party Cloud Services — Relation of Security Risks and Configuration 第三方云服务社交登录使用-安全风险与配置关系
Martin Zboril, J. Syrovátková, A. Pavlíček
Social logins offer users a simplified authentication method where they may leverage already-established social media accounts, such as with Twitter or Facebook. This concept brings users many benefits but, simultaneously, users should be aware of the multiple associated security risks. Social media users should also pay attention to the appropriate security configuration of their accounts to decrease the probability of a cyberattack. Social logins and the security configurations of social media have been broadly researched within the environment of the Czech Republic. This paper further analyzes the relation between the users' perception of security as regards social logins, the security risks associated with them, the security configuration of social media accounts, and the risk appetite of users. The authors examined the data through descriptive analysis and multi-factor analysis.
社交登录为用户提供了一种简化的身份验证方法,他们可以利用已经建立的社交媒体帐户,如Twitter或Facebook。这个概念给用户带来了许多好处,但同时,用户也应该意识到多种相关的安全风险。社交媒体用户还应注意适当的帐户安全配置,以减少网络攻击的可能性。社交登录和社交媒体的安全配置在捷克共和国的环境中得到了广泛的研究。本文进一步分析了用户对社交登录的安全感知、与之相关的安全风险、社交媒体账户的安全配置与用户风险偏好之间的关系。作者通过描述性分析和多因素分析对数据进行了检验。

Temporal Dynamics of User Engagement with U.S. News Sources on Facebook Facebook上美国新闻来源用户粘性的时间动态
Alireza Mohammadinodooshan, Niklas Carlsson
Recently, researchers have modeled how reliability and political bias of news may affect Facebook users' engagement, as measured using interaction metrics such as the number of shares, likes, etc. However, the temporal dynamics of Facebook users' engagement with news of varying degrees of bias and reliability is less studied. In light of the COVID-19 pandemic, it is also important to quantify how the pandemic changed user engagement with various news. This paper presents the first temporal study of Facebook users' interaction dynamics, accounting for both the bias and reliability of the publishers. We consider a dataset of 992 U.S. publishers, and the study spans the period from Jan. 2018 to July 2022. This allows us to accurately assess the effect of the covid outbreak on the temporal dynamics of Facebook users' interactions with different classes of news. Our study examines these two parameters' effect on Facebook user engagement using both per-publisher and aggregated statistics. Several findings are revealed by our analysis, including that publishers in different bias and reliability classes experienced significantly different levels of engagement dynamics during and following the covid outbreak. For example, we show that the least reliable news exhibited the most considerable growth of followers during the covid period and the most reliable news sources exhibited the greatest growth rate of followers during the post-covid period. We also show that the interaction rate (number of interactions normalized over the number of followers) with Facebook news posts during the post-covid period is smaller than it was even before the outbreak. Furthermore, we demonstrate how the COVID-19 outbreak caused statistically significant structural breaks in the temporal dynamics of engagement with several types of news, and quantify this effect. With social media becoming a popular news source during crises, the observed temporal dynamics provide important insights into how information was consumed over the recent years, benefiting both researchers and public sectors.
最近,研究人员对新闻的可靠性和政治偏见如何影响Facebook用户的参与度进行了建模,通过使用分享、点赞等互动指标来衡量。然而,Facebook用户对不同程度的偏见和可靠性新闻的参与的时间动态研究较少。鉴于COVID-19大流行,量化大流行如何改变用户对各种新闻的参与也很重要。本文首次对Facebook用户的互动动态进行了时间研究,同时考虑了发布者的偏差和可靠性。我们考虑了992家美国出版商的数据集,研究时间跨度从2018年1月到2022年7月。这使我们能够准确评估新冠疫情对Facebook用户与不同类别新闻互动的时间动态的影响。我们的研究考察了这两个参数对Facebook用户粘性的影响,使用了每个发行商和汇总统计数据。我们的分析揭示了几个发现,包括不同偏见和可靠性类别的出版商在新冠疫情爆发期间和之后经历了显著不同的参与动态水平。例如,我们表明,最不可靠的新闻在covid期间表现出最可观的关注者增长,而最可靠的新闻来源在后covid期间表现出最大的关注者增长率。我们还发现,在新冠肺炎疫情爆发后,用户与Facebook新闻帖子的互动率(互动次数除以关注者数量)甚至比疫情爆发前还要小。此外,我们展示了COVID-19的爆发如何在与几种新闻类型接触的时间动态中造成统计上显着的结构性断裂,并量化了这种影响。随着社交媒体成为危机期间流行的新闻来源,观察到的时间动态为了解近年来信息的消费方式提供了重要见解,使研究人员和公共部门都受益。
