An Arabic word can be described according to its lexical and morphological information. Lexical analysis consists in gathering both semantic information (meaning and translation) and syntactic properties (parts of speech). Morphological analysis, instead, identifies word patterns that group the words having the same syntactic, inflectional and semantic behaviour. Such descriptions constitute two different but complementary levels of study. This paper illustrates our work, aimed at creating an exhaustive resource consisting of two levels: lexical and morphological. The lexical level collects information extracted from the dictionary $al=qbar{a}mbar{u}s al=munderset{.}{h}bar{imath}underset{.}{t}$. The morphological level describes the word patterns. The two levels are autonomous but complementary. Each word described at the lexical level is linked to its corresponding pattern. The formalization of the word pattern makes it possible to enrich word descriptions with additional morphosyntactic and inflectional information. To obtain a digital systematic resource, we followed the guidelines provided by the Text Encoding Initiative (TEI). We adopted the TEI module devoted to encoding digital dictionaries and lexicons in order to formally represent the medieval primary source $al=qbar{a}mbar{u}s al=muunderset{.}{h}bar{imath}underset{.}{t}$. We also used the TEI interpretation approach to encode the morphological word patterns keeping the two levels separate but at the same time allowing them to be linked.
一个阿拉伯词可以根据它的词汇和形态信息来描述。词法分析包括语义信息(意义和翻译)和句法特性(词类)的收集。相反,词形分析识别的是将具有相同句法、屈折和语义行为的单词分组的单词模式。这样的描述构成了两个不同但互补的研究层次。本文说明了我们的工作,旨在创建一个详尽的资源,包括两个层次:词汇和形态。词汇层收集从字典$al=qbar{a}mbar{u}s al=munderset{.}{h}bar{imath}underset{.}{t}$中提取的信息。形态层次描述了单词的模式。这两个层次是自治的,但又是互补的。在词汇层面上描述的每个单词都与其相应的模式相关联。单词模式的形式化使得用附加的形态句法和屈折变化信息来丰富单词描述成为可能。为了获得数字系统资源,我们遵循了文本编码倡议(TEI)提供的指导方针。我们采用了专门用于编码数字词典和词典的TEI模块,以便正式表示中世纪原始来源$al=qbar{a}mbar{u}s al=muunderset{.}{h}bar{imath}underset{.}{t}$。我们还使用TEI解释方法对形态词模式进行编码,使两个层次保持分离,但同时允许它们相互联系。

The effects of COVID-19 have quickly spread around the world, testing the limits of the population and the public health sector. High demand on medical services are offset by disruptions in daily operations as hospitals struggle to function in the face of overcapacity, understaffing and information gaps. Faced with these problems, new technologies are being deployed to fight this pandemic and help medical staff governments to reduce its spread. Among these technologies, we find blockchains and Big Data which have been used in tracking, prediction applications and others. However, despite the help that these new technologies have provided, they remain limited if the data with which they are fed are not of good quality. In this paper, we highlight some benefits of using BIG Data and Blockchain to deal with this pandemic and some data quality issues that still present challenges to decision making. Finally we present a general Blockchain-based framework for data governance that aims to ensure a high level of data trust, security, and privacy.
COVID-19的影响迅速蔓延到世界各地,考验着人口和公共卫生部门的极限。对医疗服务的高需求被日常运营中断所抵消,因为医院在产能过剩、人手不足和信息缺口的情况下难以正常运作。面对这些问题,人们正在部署新技术来对抗这一流行病,并帮助医务人员政府减少其传播。在这些技术中,我们发现区块链和大数据已用于跟踪,预测应用等。然而,尽管这些新技术提供了帮助,但如果提供给它们的数据质量不高,它们仍然是有限的。在本文中,我们强调了使用大数据和区块链来应对这种流行病的一些好处,以及一些仍然对决策构成挑战的数据质量问题。最后,我们提出了一个通用的基于区块链的数据治理框架,旨在确保高水平的数据信任、安全和隐私。

This work presents a novel method to extract sub-structures in dialogues for the following genres: human-human task driven, human-human chit-chat, human-machine task driven, and human-machine chit-chat dialogues. The model consists of a novel semi-supervised annotation schema of syntactic features, communicative functions, dialogue policy, sequence expansion and sender information. These labels are then transformed into tuples of three, four and five segments, the tuples are used as features and modelled to learn sub-structures in above mentioned genres of dialogues with sequence-to-sequence variational autoencoders. The results analyse the latent space of generic sub-structures decomposed by PCA and ICA, showing an increase in silhouette scores for clustering of the latent space.

Recognizing semantic relation in sentence pairs using Tree-RNNs and Typed dependencies 使用tree - rnn和类型化依赖关系识别句子对中的语义关系

Recursive neural networks (Tree-RNNs) based on dependency trees are ubiquitous in modeling sentence meanings as they effectively capture semantic relationships between non-neighborhood words. However, recognizing semantically dissimilar sentences with the same words and syntax is still a challenge to Tree-RNNs. This work proposes an improvement to Dependency Tree-RNN (DT-RNN) using the grammatical relationship type identified in the dependency parse. Our experiments on semantic relatedness scoring (SRS) and recognizing textual entailment (RTE) in sentence pairs using SICK (Sentence Involving Compositional Knowledge) dataset show encouraging results. The model achieved a 2% improvement in classification accuracy for the RTE task over the DT-RNN model. The results show that Pearson's and Spearman's correlation measures between the model's predicted similarity scores and human ratings are higher than those of standard DT-RNNs.
基于依赖树的递归神经网络(Tree-RNNs)可以有效地捕获非邻域词之间的语义关系,因此在句子意义建模中无处不在。然而,识别具有相同单词和语法的语义不同的句子仍然是tree - rnn的一个挑战。这项工作提出了一种依赖树- rnn (DT-RNN)的改进,使用依赖解析中识别的语法关系类型。我们使用SICK (sentence related Knowledge)数据集对句子对进行语义关联评分(SRS)和文本蕴涵识别(RTE)实验,取得了令人鼓舞的结果。与DT-RNN模型相比,该模型在RTE任务的分类精度上提高了2%。结果表明,该模型预测的相似性得分与人类评分之间的Pearson’s和Spearman’s相关度量高于标准dt - rnn。

Autonomous vehicles have to meet high safety standards in order to be commercially viable. Before real-world testing of an autonomous vehicle, extensive simulation is required to verify software functionality and to detect unexpected behavior. This incites the need for accurate models to match real system behavior as closely as possible. During driving, planing and control algorithms also need an accurate estimation of the vehicle dynamics in order to handle the vehicle safely. Until now, vehicle dynamics estimation has mostly been performed with physics-based models. Whereas these models allow specific effects to be implemented, accurate models need a variety of parameters. Their identification requires costly resources, e.g., expensive test facilities. Machine learning models enable new approaches to perform these modeling tasks without the necessity of identifying parameters. Neural networks can be trained with recorded vehicle data to represent the vehicle's dynamic behavior. We present a neural network architecture that has advantages over a physics-based model in terms of accuracy. We compare both models to real-world test data from an autonomous racing vehicle, which was recorded on different race tracks with high- and low-grip conditions. The developed neural network architecture is able to replace a single-track model for vehicle dynamics modeling.
为了在商业上可行,自动驾驶汽车必须达到很高的安全标准。在对自动驾驶汽车进行实际测试之前,需要进行广泛的模拟,以验证软件功能并检测意外行为。这激发了对精确模型的需求,以尽可能接近地匹配实际系统行为。在驾驶过程中,规划和控制算法也需要对车辆动力学进行准确的估计,以保证车辆的安全运行。到目前为止,车辆动力学估计主要是通过基于物理的模型进行的。虽然这些模型允许实现特定的效果,但精确的模型需要各种参数。它们的识别需要昂贵的资源,例如昂贵的测试设备。机器学习模型支持新的方法来执行这些建模任务,而不需要识别参数。神经网络可以用记录的车辆数据来训练,以表示车辆的动态行为。我们提出了一种神经网络架构,它在准确性方面优于基于物理的模型。我们将这两种模型与来自自动驾驶赛车的真实测试数据进行了比较,这些数据是在不同的赛道上记录的,具有高抓地力和低抓地力条件。所开发的神经网络结构可以代替单轨道模型进行车辆动力学建模。

Using smart city technologies and technical advancements in Intelligent Transport Systems, this work aims to improve the safety of road users in different road environments. A new architecture of an intelligent transport system has been proposed in order to ensure the road safety in real time. The proposed Intelligent and Safe Transportation System (ISTS) consists of two components. The first is an intelligent safe traffic management system (ISTMS), the second is a safest route recommendation system (SRRS). The ISTMS uses road user's profile information and road environment data to generate and optimize a database of historical risk matrix. Security measures are also taken into account and optimized by the ISTMS in order to transform studied areas into safe ones. The SRRS uses user's profile information to recommend the safest itinerary and the most secure mode of transportation ensuring the user's safety.

Nowadays, Deep learning becomes the most powerful black box predictors, which has achieved a high performance in many fields such as insurance especially in fraud detection, claims management, pricing, etc. Despite these achievements, the main interest of these classic deep learning networks is to focus only on improving the accuracy of the model without assessing the quality of the outputs. In other words, classic deep learning networks do not incorporate uncertainty information but it consists only in returning a point prediction. Knowing how much confidence there is in a prediction is essential for gaining insurers' trust in technology. In this work, we propose a solution to detect automobile insurance fraud with quantified uncertainty, our model uses two methods to quantify uncertainty. The first one is called Monte Carlo Dropout method, which is considered as an approximate Bayesian inference in deep Gaussian processes. The second is named Deep Ensembles method. These two methods mitigate the problem of representing uncertainty in deep learning without sacrificing either computational complexity or test accuracy. We found that our proposed method gives good results in comparison to the existing methods on the automobile insurance data set “carclaims.txt”.
如今,深度学习已经成为最强大的黑箱预测器,在保险领域尤其是欺诈检测、理赔管理、定价等领域取得了优异的成绩。尽管取得了这些成就,但这些经典深度学习网络的主要兴趣是只关注提高模型的准确性,而不评估输出的质量。换句话说,经典的深度学习网络不包含不确定性信息,而只是返回一个点预测。要获得保险公司对技术的信任,了解人们对预测的信心有多大至关重要。在本文中,我们提出了一种具有量化不确定性的汽车保险欺诈检测方法,我们的模型使用两种方法来量化不确定性。第一种方法被称为蒙特卡罗Dropout方法,它被认为是深度高斯过程中的近似贝叶斯推理。第二种方法是深度集成方法。这两种方法在不牺牲计算复杂性和测试准确性的情况下减轻了深度学习中表示不确定性的问题。在车险数据集carclaims.txt上,与已有的方法相比,我们的方法取得了较好的效果。

The studied mining production chain generally divided into three principal units: Destoning, screening and loading. The role of the screening unit is to screen the phosphate produced by the destoning unit before the loading to trains. Its efficiency depends on several parameters, which makes analysis and decision making for its improvement very complicated. The purpose of this paper is to propose a prediction system to evaluate and monitor in advance the efficiency of the screening unit. This system is based on Knowledge discovery in databases that comprises generally three steps: data pre-processing, development of prediction models and finally validation and verification of the proposed models. The first consists in having in-depth information and knowledge about the application domain, in order to determine the set of parameters influencing the efficiency and to pre-process the data of the these parameters, in order to improve their quality before being used by the second step, which aims to develop predictive models that will be validated and verified with different evaluation criteria during the last step. This work focuses on the first level of development of the system in question, data pre-processing, which has been applied to the mine's screening unit facilities, and the results of this case study are also presented.
所研究的采矿生产链一般分为三个主要单元:选石、筛分和装载。筛分装置的作用是在装车前对脱石装置产生的磷酸盐进行筛分。它的效率取决于几个参数,这使得对其改进的分析和决策非常复杂。本文的目的是提出一个预测系统,以提前评估和监测筛选单元的效率。该系统基于数据库中的知识发现,一般包括三个步骤:数据预处理,开发预测模型,最后验证和验证所提出的模型。第一步是深入了解应用领域的信息和知识,以确定影响效率的一组参数,并对这些参数的数据进行预处理,以提高其质量,然后再用于第二步。第二步的目的是建立预测模型,并在最后一步中使用不同的评估标准进行验证和验证。这项工作的重点是该系统的第一阶段开发,即数据预处理,该技术已应用于矿山的筛选单元设施,并介绍了该案例研究的结果。

The shift towards digital teaching is leading to an increased need for interactive teaching methods. Game-Based Learning combines teaching content with a motivating application. The learning simulation Finanzmars uses elements from Game-Based Learning to prepare the contents of a classical lecture in the field of economics for a learning game. The simulation is aimed at students of business administration or similar courses of study. The contents can be edited and extended directly by the teaching staff using an external configuration tool. The knowledge transfer is flanked by Micro Learning, systematic introductions to increasingly complex subjects, interaction with game elements and increased motivation through in-game successes such as a premium currency. The player finds himself in an economic simulation with the goal of exploiting the resources of Mars in a profitable and optimized way. In the game, construction, upgrading and repair of buildings, the development of future technology through research, the export of resources and expansion to other celestial bodies are available. The functionalities are based on possible courses of action in the real world, whose mechanisms play a central role in the lecture on the topic of finance. By means of logging and the evaluation of in-game objectives, the teachers can track the progress of the students. Our evaluation of 12 Master's students in Business Administration shows that there is an increase in economic expertise. Furthermore, the evaluation of the associated standardized AttrakDiff questionnaire according to DIN EN ISO 9241–11 certifies that the application is action-oriented and user-friendly. The description of the environment with regard to the course of studies and the teaching concept was largely done in the publication “Finanzmars im Kosmos von Blended Learning” by Marc Ritter, Christian Roschke and Volker Tolkmitt, who received the Best Paper Award in Teaching at the CARF Lucerne Conference in 2019. This publication focuses on the systematic elaboration of game design and implementation with a view to increasing learning success.
向数字化教学的转变导致对互动式教学方法的需求增加。基于游戏的学习将教学内容与激励应用相结合。学习模拟Finanzmars使用基于游戏的学习(game - based learning)的元素为学习游戏准备经济学领域经典讲座的内容。模拟是针对工商管理或类似课程的学生。教学人员可以使用外部配置工具直接编辑和扩展内容。知识转移伴随着微学习,系统地介绍越来越复杂的主题,与游戏元素的互动以及通过游戏内的成功(如付费货币)增加动机。玩家发现自己处于经济模拟中,目标是以盈利和优化的方式开发火星资源。在游戏中,可以建造、升级和修复建筑物,通过研究开发未来技术,出口资源并扩展到其他天体。这些功能基于现实世界中可能的行动方案,其机制在金融主题讲座中发挥了核心作用。通过记录和游戏目标的评估,教师可以跟踪学生的进度。我们对12名工商管理硕士学生的评估显示,经济专业知识有所增加。此外,根据DIN EN ISO 9241-11对相关标准化AttrakDiff问卷的评估证明,该应用程序是面向行动和用户友好的。关于学习过程和教学概念的环境描述主要在Marc Ritter, Christian Roschke和Volker Tolkmitt的出版物“Finanzmars im Kosmos von Blended Learning”中完成,他们在2019年的CARF Lucerne会议上获得了教学最佳论文奖。本出版物着重于系统阐述游戏设计和实施,以期提高学习成功率。
