Platform Neutrality and the Global Balance of Powers 平台中立与全球力量平衡
Marcel S. Stolz
This paper defines platform neutrality as a concept for large technology companies, most notably, social media platform providers. It is deduced from the concept of state neutrality, and acknowledges societal and political functions as well as state-like structures these companies have put into place. The paper argues that recent developments demonstrate a convergence of social media towards platform neutrality. It explains the benefit of platform neutrality both for businesses as well as societies.
本文将平台中立性定义为大型科技公司,尤其是社交媒体平台提供商的概念。它是从国家中立的概念推导出来的,并承认这些公司已经实施的社会和政治功能以及类似国家的结构。本文认为,最近的发展表明,社交媒体正在向平台中立性靠拢。它解释了平台中立性对企业和社会的好处。

Machine Learning for Multiple Stage Phishing URL Prediction 多阶段网络钓鱼URL预测的机器学习
Khalid Amen, Mohamad Zohdy, M. Mahmoud
Phishing is a fraudulent process and a form of cybercrime where an attacker tries to obtain sensitive information for malicious use. A phisher uses social engineering and technical deception to fetch private information from the web user. Previous Machine Learning (ML) approaches have been used to detect whether URLs are valid, or invalid. The purpose of this work is to detect, or predict, the three stages of Phishing URLs starting with valid, not enough info and invalid URLs. We will investigate different potential models that are trained by Machine Learning algorithms and find out which of these models has better accuracy.
网络钓鱼是一种欺诈过程,也是网络犯罪的一种形式,攻击者试图获取敏感信息以进行恶意使用。网络钓鱼者使用社会工程和技术欺骗从网络用户那里获取私人信息。以前的机器学习(ML)方法已用于检测url是否有效或无效。这项工作的目的是检测或预测网络钓鱼url的三个阶段,从有效、信息不足和无效的url开始。我们将研究由机器学习算法训练的不同潜在模型,并找出哪些模型具有更好的准确性。

A Deep Learning BERT-Based Approach to Person-Job Fit in Talent Recruitment 人才招聘中基于深度学习bert的人职契合度分析
E. Abdollahnejad, Marilynn Kalman, B. Far
Although the widespread use of the Internet provides job recruiters with a larger pool to select the most qualified candidates, the tedious process of going over hundreds of resumes makes a fair and objective decision making more difficult. This paper proposes an end-to-end BERT-based framework to decrease the workload and expedite the shortlisting process of job applicants. Utilizing historical-records data of thousands failed and successful job applications, our model simulates the recruiters’ decision-making process by the state-of-the-art BERT algorithm. The results show that BERT outperforms a variety of models by a high margin.

An Enhanced VoIP Codec Transcoder to Enhance VoIP Quality for IP Telephone Infrastructure 一种增强的VoIP编解码器转码器以提高IP电话基础设施的VoIP质量
Thubelihle S. Zulu, Topside E. Mathonsi
Poor VoIP quality in IP telephone infrastructure is a major concern and it can affect business growth, especially to businesses that deal with interacting with a client over the phone. Speech or audio signals are usually affected by codec mismatch, packet loss, and jitter which affect user perception of voice quality. VoIP telephone system is growing at a rapid speed and has received much attention because of their call cost internationally and national and fewer resources needed compared to traditional voice telephone systems or public switched telephone networks. The main aim of this paper is to develop a solution that will provide an enhanced voice quality in VoIP platform systems by implementing the amended VoIP codec transcoding system that auto negotiates VoIP codec with the intention of preventing VoIP codec mismatch via standalone and software VoIP codec transcoding system. An experimental research with technological tools such as SIP (Session Initiation Protocol) phone, asterisk PBX (Private Branch Exchange) systems and SBC (Session Border Control) will be conducted. A practical test will be carried out in any working environment with the converged network in order to test results or findings to solve the problem of codec mismatch with the intention of enhancing Voice quality and avoiding calls dropping issues in IP telephone infrastructure. This paper is introducing an amended VoIP codec transcoding system that auto-negotiate VoIP codec in order to prevent codec mismatch and enhance voice quality hence codec mismatch is not only the major concern for VoIP quality, VoIP quality can be affected by many factors, such as packet loss, jitter, packet delay, and bandwidth but this paper is focusing on the codec mismatch.
IP电话基础设施中较差的VoIP质量是一个主要问题,它会影响业务增长,特别是对那些通过电话与客户进行交互的业务。语音或音频信号通常会受到编解码器不匹配、丢包和抖动的影响,从而影响用户对语音质量的感知。与传统的语音电话系统或公共交换电话网相比,VoIP电话系统由于其呼叫成本低、所需资源少等优点,正在迅速发展,并受到国际和国内的广泛关注。本文的主要目的是开发一种解决方案,通过实施修改后的VoIP编解码器转码系统,该系统可以自动协商VoIP编解码器,目的是通过独立和软件VoIP编解码器转码系统防止VoIP编解码器不匹配,从而在VoIP平台系统中提供增强的语音质量。将利用SIP(会话发起协议)电话、asterisk PBX(专用分支交换)系统和SBC(会话边界控制)等技术工具进行实验研究。将在融合网络的任何工作环境中进行实际测试,以测试结果或发现,以解决编解码器不匹配的问题,以期提高语音质量和避免IP电话基础设施中的掉线问题。本文介绍了一种改进的VoIP编解码器转码系统,该系统可以自动协商VoIP编解码器,以防止编解码器不匹配,提高语音质量。因此,编解码器不匹配不仅是VoIP质量的主要问题,VoIP质量会受到许多因素的影响,如丢包、抖动、数据包延迟和带宽,但本文重点研究了编解码器不匹配。

Time is Important in Fake News Detection: a short review 在假新闻检测中,时间很重要:简短回顾
Shubhangi Rastogi, D. Bansal
The prevalence of fake news has augmented with the rise of digital sources, especially social media. In this paper, current fake news research is studied and examined to offer a succinct road-map for future work. The paper presents a novel three-tier system depending on the lifespan of news and divides the research in three phases: early, mid and late-stage detection. The strategy to be followed for fake news detection varies with the time of detection. Fake news has shown adverse effects in a very short time period of propagation on social media. To mitigate this, it is required to detect fake news at an early stage when limited information about the news is available. In contrast, rich information can be examined like user engagement, propagation patterns, etc., at a later stage when news is deeply spread in the social network. Therefore, it is important to first analyze the time when the news disseminated, and then follow a suitable fake news detection methodology presented in the-state-of-the-art.
随着数字来源(尤其是社交媒体)的兴起,假新闻的流行程度也在加剧。本文对当前的假新闻研究进行了研究和检验,为未来的工作提供了一个简洁的路线图。本文根据新闻的生命周期提出了一种新的三层体系,并将研究分为早期、中期和后期三个阶段。假新闻侦查的策略随着侦查时间的不同而不同。假新闻在社交媒体上的传播在很短的时间内就显示出了负面影响。为了减轻这种情况,需要在新闻信息有限的早期阶段发现假新闻。而丰富的信息则需要等到新闻在社交网络中深入传播的后期,才能进行用户参与度、传播模式等方面的检验。因此,重要的是首先分析新闻传播的时间,然后遵循最先进的合适的假新闻检测方法。

Convolutional Neural Networks for Morphologically Similar Fish Species Identification 形态相似鱼类识别的卷积神经网络
Dena F. Mujtaba, N. Mahapatra
Seafood comprises the largest globally traded food commodity in the world. Its supply chains are complex, focus on quick distribution, and rely on processing practices that make it difficult to trace products to their source. This has resulted in seafood mislabeling, with investigations revealing mislabeling of more than 30% of marketed seafood products, though the full extent of seafood mislabeling in the U.S. is unknown. When two species are morphologically similar, it is difficult for humans to visually distinguish between them, thus making mislabeling difficult to detect. To address this problem, we present a novel deep-learning-based model to distinguish between morphologically similar fish species in images. Our approach uses transfer learning with state-of-the-art convolutional neural networks (CNN) to build upon previously learned features on millions of images, thereby improving the model’s classification accuracy. We compare three pretrained CNNs: VGG, ResNet, and RegNet. For evaluation, we utilize the FishNet Open Image Database, containing over 85,000 images from electronic monitoring footage of fisheries. We train and test two models: a 4-species classifier of visually-similar tuna species, and a binary classifier of visually-indistinguishable tuna often mislabeled. Our results show CNNs can be used to distinguish between morphologically similar fish species with high accuracy, which otherwise would often be mislabeled by humans.
海产品是世界上最大的全球贸易食品。它的供应链很复杂,注重快速分销,依赖于难以追踪产品来源的加工实践。这导致了海产品贴错标签,调查显示,超过30%的上市海产品贴错标签,尽管美国海产品贴错标签的全部程度尚不清楚。当两个物种在形态上相似时,人类很难在视觉上区分它们,从而使错误标签难以发现。为了解决这个问题,我们提出了一种新的基于深度学习的模型来区分图像中形态相似的鱼类。我们的方法使用最先进的卷积神经网络(CNN)的迁移学习,在数百万张图像上建立先前学习的特征,从而提高模型的分类精度。我们比较了三种预训练的cnn: VGG, ResNet和RegNet。为了进行评估,我们利用渔网开放图像数据库,其中包含85,000多张来自渔业电子监控录像的图像。我们训练和测试了两个模型:一个是视觉上相似的金枪鱼种类的4种分类器,另一个是视觉上难以区分的金枪鱼经常被错误标记的二元分类器。我们的研究结果表明,cnn可以用于区分形态相似的鱼类,准确度很高,否则通常会被人类错误标记。

Utilizing HAPS Deployed Data Centers in Offloading Cloud Workloads 利用HAPS部署的数据中心卸载云工作负载
T. Ovatman, Muhammed Enes Tırnakçı, A. Yılmaz
Recent advances in communication technology has begun to push the data centers towards high altitude platform stations (HAPS) due to their advantages in communication coverage, mobility and cooling. There are plenty of studies that focus on the communication aspects of such devices but the issues regarding deploying micro data centers on HAPS is rarely studied. In the future, there is a potential for a substantial amount of processing power to be offload to such stations to back up terrestrial stations in fog computing scenarios. In this study we have analyzed cloud workload handling and power consumption efficiencies of two different HAPS deployment scenarios. In our simulations, performed with CloudSim Plus, we have experimented with scenarios with varying number of lower and higher altitude HAPS and terrestrial base stations. In our experiments we have identified the trade-offs and cases to provide better performance in handling cloud workloads.
由于高空平台站(HAPS)在通信覆盖、移动性和冷却方面的优势,通信技术的最新进展已开始推动数据中心向高空平台站(HAPS)发展。有大量的研究集中在这些设备的通信方面,但关于在HAPS上部署微型数据中心的问题很少研究。未来,在雾计算场景中,有可能将大量的处理能力卸载给这些站,以支持地面站。在本研究中,我们分析了两种不同HAPS部署场景的云工作负载处理和功耗效率。在我们使用CloudSim Plus进行的模拟中,我们对不同数量的低海拔HAPS和地面基站进行了实验。在我们的实验中,我们已经确定了在处理云工作负载时提供更好性能的权衡和案例。

Sublinear evaluation of complex networks for extensive exploration of configurations for critical scenarios and decision making 复杂网络的亚线性评估,用于广泛探索关键场景和决策的配置
A. Delbem, A. Saraiva, J. London, R. Fanucchi
Artificial Intelligence in Complex Networks has contributed to several relevant fields involving energy systems, computer networks, environment, agriculture, health, and social organizations. However, investigations concerning multiple heterogeneous networks have been less frequent. Mixed systems usually require fine-grained data to retain a sufficient amount of details from each network. This type of modeling may enable the investigation of emerging behaviors or synergies. For example, a decision making may require the search for an improved network configuration (involving coarse and fine modifications on devices, procedures, and settings) with the lowest possible cost to soon mitigate effects from climate changes or other types of "attacks" (from economic crises, calamities, and recent pandemics). The generation of robust configurations for heterogeneous networks involves some challenges, pointed out in this paper. Among them, the efficient calculus of load flows has been one of the main challenges. To overcome it, we propose a load flow algorithm with sublinear time complexity for the construction and evaluation of several configurations. The new algorithm scales well and can deal with nonlinear dynamics in evaluations of entire sets of fine-grained network models that it may involve.
复杂网络中的人工智能对能源系统、计算机网络、环境、农业、卫生和社会组织等多个相关领域做出了贡献。然而,对多个异构网络的研究却很少。混合系统通常需要细粒度的数据来保留来自每个网络的足够数量的细节。这种类型的建模可以对新出现的行为或协同作用进行调查。例如,一项决策可能需要以尽可能低的成本寻找改进的网络配置(包括对设备、程序和设置进行粗细修改),以尽快减轻气候变化或其他类型的“攻击”(来自经济危机、灾难和最近的流行病)的影响。本文指出了异构网络鲁棒配置的生成所面临的一些挑战。其中,有效的潮流计算一直是主要的挑战之一。为了克服这一问题,我们提出了一种具有亚线性时间复杂度的负荷流算法,用于构建和评估几种配置。新算法具有良好的可扩展性,可以处理可能涉及的整组细粒度网络模型的非线性动态评估。

This paper will cover the planning and development of cloud applications that are used in the workplace. In addition to researching the feature needs of these applications, we will examine the risks and rewards of using these cloud applications for businesses. For instance, we go into how cloud software could be used in education as well as for small business and dive into the benefits that can be obtained from both. On the other hand, when conducting business on the cloud, there is always a risk that your data can be intercepted by an unwanted party through scripting or injection attacks. With the cloud becoming larger every year, we also dive into the European Union (EU) and the United States (US) privacy regulators and how they act in favor of the consumer, so that their data and rights are protected. Finally, we examine the many different scaling techniques and infrastructure providers can elect to deploy a combination of them, so that service quality does not degrade with an increase of traffic.
本文将介绍在工作场所使用的云应用程序的规划和开发。除了研究这些应用程序的功能需求之外,我们还将研究为企业使用这些云应用程序的风险和回报。例如,我们将探讨如何在教育和小型企业中使用云软件,并深入研究可以从两者中获得的好处。另一方面,在云上开展业务时,始终存在数据可能被不受欢迎的一方通过脚本或注入攻击拦截的风险。随着云计算每年变得越来越大,我们还深入了解了欧盟(EU)和美国(US)的隐私监管机构,以及他们如何采取有利于消费者的行动,从而保护他们的数据和权利。最后,我们研究了许多不同的扩展技术,基础设施提供商可以选择部署它们的组合,这样服务质量就不会随着流量的增加而降低。
