Resource Description Framework (RDF) is designed as a standard metadata model for data interchange on the Internet. Because of machine comprehensibility, it has been successfully used in many areas, such as the intelligent processing of numerous data. While the generation of RDF with relational database (RDB) receives much attention, little effort has been put into the automatic construction of RDF with HBase due to its flexible data structure. Since more data is stored in HBase, it is necessary to extract useful information from HBase. In this paper, we are devoted to construction of RDF with HBase. We put forward formal definitions of RDF and HBase and propose our strategy for generating RDF with HBase. We develop a prototype system to create RDF, and test results demonstrate the feasibility of our method.
资源描述框架(RDF)被设计为Internet上数据交换的标准元数据模型。由于机器可理解性,它已经成功地应用于许多领域,如大量数据的智能处理。虽然使用关系数据库生成RDF (relational database, RDB)受到了广泛的关注,但由于HBase的数据结构灵活,因此在使用HBase自动构建RDF方面投入的精力很少。由于HBase中存储了更多的数据,因此有必要从HBase中提取有用的信息。在本文中,我们致力于用HBase构建RDF。提出了RDF和HBase的形式化定义,并提出了利用HBase生成RDF的策略。我们开发了一个原型系统来创建RDF,测试结果证明了我们方法的可行性。

Instances of hate speech on popular social media platforms such as Twitter are becoming increasingly common and intense. However, there still exists a lack of comprehensive deeplearning models to combat Twitter hate speech. In this project, a comprehensive detection and reporting platform, entitled “TweetWatch,” was created to solve this issue. A binary classification CNN (Convolutional Neural Network) and a multi-class CNN were created to detect hate speech from real-time Twitter data and classify tweets with hate speech into five categories. The binary classification model has an AUC score of 98.95% and an F1 score of 97.88%. The multi-class classification model has an AUC score of 89.46%. All metrics reached over a targeted 5% increase from previous models in multiple papers, validating the proposed solution. Additionally, the only real-time choropleth map for hate speech in the United States was successfully created.
在Twitter等热门社交媒体平台上,仇恨言论变得越来越普遍和激烈。然而,目前仍然缺乏全面的深度学习模型来对抗推特上的仇恨言论。在这个项目中,我们创建了一个名为“TweetWatch”的综合检测和报告平台来解决这个问题。创建了一个二元分类CNN(卷积神经网络)和一个多分类CNN,从实时Twitter数据中检测仇恨言论,并将含有仇恨言论的推文分为五类。二元分类模型的AUC得分为98.95%,F1得分为97.88%。多类分类模型的AUC得分为89.46%。在多篇论文中,所有指标都比之前的模型增加了5%以上的目标,验证了所建议的解决方案。此外,成功创建了美国唯一的仇恨言论实时地图。

The latest research shows the benefits, the impact, and the usage of Blockchain and decentralized systems with a high confidence. Its popularity becomes even higher with the electronic voting systems based on the technology itself. In this paper we propose a new implementation of an electronic voting system based on Blockchain using ECDSA with blind signatures. Additionally, the system is compared with other electronic voting systems based on Blockchain technology. Mainly these types of systems hardly ever fulfill the scalability. Nevertheless, our system has an advantage in comparison with the other systems. Since the idea of the Blockchain technology is to show the flexibility and equal privileges to all nodes, this implementation with Angular and Spring Boot shows that, so everyone can track the chain. To sum up, this implementation can have a good usage in smaller departments, because of the performances and all mathematical operations.
最新的研究显示了区块链和去中心化系统的好处、影响和使用。基于该技术本身的电子投票系统使其受欢迎程度更高。在本文中,我们提出了一种基于区块链的电子投票系统的新实现,该系统使用了带有盲签名的ECDSA。此外,还将该系统与其他基于区块链技术的电子投票系统进行了比较。主要是这些类型的系统几乎没有实现可伸缩性。然而,与其他系统相比,我们的系统有优势。由于区块链技术的理念是向所有节点展示灵活性和平等的特权,因此使用Angular和Spring Boot的实现表明了这一点,因此每个人都可以跟踪链。总而言之,由于性能和所有数学运算,这种实现在较小的部门中可以很好地使用。

Anxiety is a chronic illness especially during the Covid and post-pandemic era. It’s important to diagnose anxiety in its early stages. Traditional Machine learning (ML) methods have been developmental intense procedures to detect mental health issues, but Automated machine learning (AutoML) is a method whereby the novice user can build a model to detect a phenomenon such as Generalized Anxiety Disorder (GAD) fairly easily. In this study we evaluate a popular AutoML technique with recent chat engine (Discord) conversation dataset using anxiety hashtags. This multi-symptom AutoML Random Forest predictive model is at least 75+% accurate with the most prevalent symptom, namely restlessness. This could be a very useful first step in diagnosing GAD by medical professionals and their less skilled hospital’s IT area using pre diagnostic textual conversations. But it lacks high quality in predicting GAD in most symptoms as found by a low 50% precision on most symptoms (except 5). The AutoML technology is quicker for IT professionals and gives a decent performance, but it can be improved upon by more sophisticated ANN methods like Convolution neural networks that plug AutoML’s symptom’s deficiencies with at least 80+% precision and 0.4+% in F1 score, namely in detecting poorly predicted symptoms of concentration and irritability.
焦虑是一种慢性病,尤其是在新冠疫情和大流行后时代。在早期阶段诊断焦虑是很重要的。传统的机器学习(ML)方法已经发展为检测心理健康问题的密集程序,但自动机器学习(AutoML)是一种方法,新手用户可以建立一个模型来相当容易地检测广泛性焦虑障碍(GAD)等现象。在本研究中,我们使用焦虑标签评估了最近聊天引擎(Discord)对话数据集的流行AutoML技术。这种多症状AutoML随机森林预测模型对于最普遍的症状,即躁动,至少有75%以上的准确率。这可能是医学专业人员和他们技术较差的医院IT领域使用诊断前文本对话诊断广泛性焦虑症的非常有用的第一步。但它在预测大多数症状的广泛性焦虑症方面缺乏高质量,因为大多数症状的准确率低于50%(除了5)。AutoML技术对it专业人员来说更快,表现也不错,但它可以通过更复杂的人工神经网络方法得到改进,比如卷积神经网络,它可以以至少80% +%的准确率和0.4+%的F1分数来弥补AutoML症状的不足,即检测注意力集中和易怒等预测不佳的症状。

The issue of finding a clean and simple player movement implementation that the general public will find intuitive and easy to use has been tackled over the years in various ways. With FPS (first-person shooter) games, the need fora simple and fun style of movement is monumentally crucial, as that will be a core aspect of the gameplay [4]. To address this issue, an FPS game was created with the ability to maintain momentum while crouching with intention of providing a smoother and more intuitive gaming experience for players. This movement implementation was tested by having participants play the game for a sufficient amount of time, then asking the participants to rate the experience of movement in the game and the overall enjoyment of playing the game. The results indicate that the implemented movement would be well-received by the general public, as the vast majority of the participants viewedthe new form of movement as a welcome feature based on the optional feedback and the quantitative ratings. However, the other aspects of the gameplay were not as polished and therefore lowered the overall enjoyment of the game for the participants, particularly the shooting in the game that does not yet have proper audio or visual cues tolet the player know that the weapon has been fired.
多年来,我们一直在以各种方式解决如何找到一种清晰且简单的玩家移动执行方法,让大众觉得它直观且易于使用。对于FPS(第一人称射击游戏)来说,简单而有趣的移动风格至关重要,因为这将成为游戏玩法的核心元素[4]。为了解决这个问题,我们创造了一款能够在蹲伏时保持动力的FPS游戏,目的是为玩家提供更流畅、更直观的游戏体验。通过让参与者玩游戏足够长的时间,然后让参与者对游戏中的移动体验和玩游戏的整体乐趣进行评价,来测试这种移动执行。结果显示,实施的运动将受到公众的欢迎,因为绝大多数参与者认为基于可选反馈和定量评分的新形式的运动是一个受欢迎的功能。然而,游戏玩法的其他方面并没有得到完善,因此降低了参与者的整体游戏乐趣,特别是游戏中的射击还没有适当的音频或视觉线索让玩家知道武器已经发射。

A NLP-learning Powered Customizable Approach Towards Auto-blocking Distracting Websites 一种基于nlp学习的自定义方法,用于自动阻止分散注意力的网站
Pub Date : 2023-01-28 DOI: 10.5121/csit.2023.130209
Yulin Zhang, Yu Sun
Over the past few decades, the problem of distraction and its accompanying side effects has taken its root deeply in all parts of our daily life and extended its ever-increasing influences among young generations [2]. In addition to its alarming prevalence, another characteristic of distraction that raises most concerns is how easily we can get distracted from our tasks at hand while using the electronic devices as a means of solving problems [3]. This paper attempts to address this society-wide problem thoroughly and universally through a technical approach of detecting, analyzing, and blocking the websites intelligently. Our design highlights the applications of machine learning and natural language processing, and is implemented purely in Python, Javascript, and several other web development languages. After retrieving the web content from the target websites through the web scraping process, summarizing the data to a number of short paragraphs via the use of NLP, we were able to perform data analysis on the result and finally block the websites accordingly [4]. With the help of this extension, students and those who wish to improve their concentration in work will be able to put more focus on the tasks at hand and thus boost their work efficiency under any working conditions.
在过去的几十年里,注意力分散的问题及其伴随的副作用已经深深扎根于我们日常生活的方方面面,并对年轻一代的影响越来越大[2]。除了其惊人的普遍性外,分心的另一个最令人担忧的特点是,当我们使用电子设备作为解决问题的手段时,很容易从手头的任务中分心[3]。本文试图通过一种智能检测、分析和屏蔽网站的技术方法,彻底解决这一社会普遍存在的问题。我们的设计突出了机器学习和自然语言处理的应用,并且完全使用Python, Javascript和其他几种web开发语言实现。在通过网页抓取过程从目标网站检索到网页内容后,通过使用NLP将数据汇总为一些简短的段落,我们能够对结果进行数据分析,并最终相应地屏蔽网站[4]。在这个扩展的帮助下,学生和那些希望提高工作集中力的人将能够把更多的注意力放在手头的任务上,从而提高他们在任何工作条件下的工作效率。

A Cryptocurrency Analysis Tool based on Social Metrics 基于社交指标的加密货币分析工具
Pub Date : 2023-01-28 DOI: 10.5121/csit.2023.130206
Bill Xu, Yu Sun
Recent years have witnessed the dramatic popularity of cryptocurrencies, in which millions invest to join the cryptocurrency community or make financial gains [1]. Investors employ many ways to analyze a cryptocurrency, from a purely technical approach to a more utility-centred approach [2]. However, few technologies exist to help investors find cryptocurrencies with bright prospects through social metrics, an equally if not more important viewpoint to consider due to the importance of communities in the space. This paper proposes an application to evaluate cryptocurrencies based on social metrics by establishing scores and models with machine learning and other tools [3]. We verified the need for our application through surveys, applied it to test investment strategies, andconducted a qualitative evaluation of the approach. The results show that our tool benefits investors by providing them with a different lens to view cryptocurrencies and helps them make more thorough decisions.
近年来,加密货币急剧流行,数百万人投资加入加密货币社区或获得经济收益[1]。投资者采用多种方法来分析加密货币,从纯粹的技术方法到更加以实用为中心的方法[2]。然而,很少有技术可以帮助投资者通过社交指标找到具有光明前景的加密货币,由于社区在该领域的重要性,这是一个同样重要的观点。本文提出了一种应用程序,通过使用机器学习和其他工具建立分数和模型来评估基于社交指标的加密货币[3]。我们通过调查验证了我们的应用程序的必要性,将其应用于测试投资策略,并对该方法进行了定性评估。结果表明,我们的工具通过为投资者提供不同的视角来看待加密货币,并帮助他们做出更彻底的决策,从而使投资者受益。

Autonomous robots will need to form relationships with humans that are built on reliability and (social) trust. The source of reliability and trust in human relationships is (human) ethical competence, which includes the capability of moral decision-making. As autonomous robots cannot act with the ethical competence of human agents, a kind of human-like ethical competence has to be implemented into autonomous robots (AI-systems of various kinds) by way of ethical algorithms. In this paper I suggest a model of the general logical form of (human) meta-ethical arguments that can be used as a pattern for the programming of ethical algorithms for autonomous robots.
自主机器人将需要在可靠性和(社会)信任的基础上与人类建立关系。人际关系中可靠和信任的来源是(人的)伦理能力,其中包括道德决策的能力。由于自主机器人无法以人类代理人的道德能力行事,因此必须通过道德算法将一种类似人类的道德能力实现到自主机器人(各种人工智能系统)中。在本文中,我提出了一个(人类)元伦理论证的一般逻辑形式的模型,可以用作自主机器人伦理算法编程的模式。

Micam: Visualizing Feature Extraction of Nonnatural Data Micam:非自然数据的可视化特征提取
Pub Date : 2023-01-28 DOI: 10.5121/csit.2023.130201

Convolutional Neural Networks (CNN) continue to revolutionize image recognition technology and are being used in non-image related fields such as cybersecurity. They are known to work as feature extractors, identifying patterns within large data sets, but when dealing with nonnatural data, what these features represent is not understood. Several class activation map (CAM) visualization tools are available that assist with understanding the CNN decisions when used with images, but they are not intuitively comprehended when dealing with nonnatural security data. Understanding what the extracted features represent should enable the data analyst and model architect tailor a model to maximize the extracted features while minimizing the computational parameters. In this paper we offer a new tool Model integrated Class Activation Maps, (MiCAM) which allows the analyst the ability to visually compare extracted feature intensities at the individual layer detail.

卷积神经网络(CNN)继续革新图像识别技术,并被用于网络安全等非图像相关领域。众所周知,它们作为特征提取器工作,识别大型数据集中的模式,但是当处理非自然数据时,这些特征代表什么就不被理解了。当与图像一起使用时,有几个类激活图(CAM)可视化工具可以帮助理解CNN决策,但在处理非自然安全数据时,它们不能直观地理解。了解提取的特征表示什么应该使数据分析师和模型架构师能够定制模型,以最大化提取的特征,同时最小化计算参数。在本文中,我们提供了一个新的工具模型集成类激活图(MiCAM),它允许分析人员能够在单个层细节上直观地比较提取的特征强度。我们探索使用这个新工具来分析几个数据集。首先,MNIST手写数据集获得基线理解。然后,我们分析了两个安全数据集:来自受恶意软件感染的基于云的应用服务器的计算机处理指标和CIC-IDS-2017 IP数据流量集,并确定重新排序非自然安全相关数据如何影响特征提取性能,以及确定重新排序数据如何影响特征提取性能。

We aim to tackle the issue of improving the global situation regarding climate change by creating a mobile application named Climerry, which educates its users on recent news related to climate on the home screen. Climerry also features a second tab that allows users to view opportunities to improve the climate change situation in the vicinity by typing in a ZIP code or city name. Some examples of opportunities include beach cleanups and tree-planting sessions. By informing and encouraging the general public to become more involved in the effort to preserve our planet, the negative effects of climate change may be much less significant in the future. To prove the effectiveness of this application in encouraging the general public to take action against climate change, one experiment was performed to gauge how much knowledge regarding climate change the participants had gained by using the application. Another experiment tested the reliability of the news API used in the application by testing the accuracy of information in each of the selected articles in the featured news section of the application. The result of the experiments indicated that the application is useful when it comes to providing accurate news and educating its users on the topic of climate change.
我们的目标是通过创建一个名为Climerry的移动应用程序来解决改善全球气候变化状况的问题,该应用程序可以在主屏幕上教育用户有关气候的最新新闻。Climerry还提供了第二个选项卡,用户可以通过输入邮政编码或城市名称来查看改善附近气候变化情况的机会。一些机会的例子包括海滩清理和植树会议。通过告知和鼓励公众更多地参与到保护地球的努力中来,气候变化的负面影响在未来可能会小得多。为了证明该应用程序在鼓励公众采取行动应对气候变化方面的有效性,我们进行了一个实验,以衡量参与者通过使用该应用程序获得了多少关于气候变化的知识。另一个实验测试了应用程序中使用的新闻API的可靠性,通过测试应用程序的特色新闻部分中每篇选定文章中的信息的准确性。实验结果表明,该应用程序在提供准确的新闻和教育用户有关气候变化主题方面是有用的。
