“…Previous related studies applied different methods for labeling and compiling datasets, as shown in Tables 2 and 3 . In this study, we followed the most frequently used annotation strategy described in the literature (Ibrohim & Budi, 2018 ; Rezvan et al, 2018 ). We asked a judgment group of five Arabic native speakers to label the tweets manually.…”

Cyberbullying (CB) is classified as one of the severe misconducts on social media. Many CB detection systems have been developed for many natural languages to face this phenomenon. However, Arabic is one of the under-resourced languages suffering from the lack of quality datasets in many computational research areas. This paper discusses the design, construction, and evaluation of a multi-dialect, annotated Arabic Cyberbullying Corpus (ArCybC), a valuable resource for Arabic CB detection and motivation for future research directions in Arabic Natural Language Processing (NLP). The study describes the phases of ArCybC compilation. By way of illustration, it explores the corpus to discover strategies used in rendering Arabic CB tweets pulled from four Twitter groups, including gaming, sports, news, and celebrities. Based on thorough analysis, we discovered that these groups were the most susceptible to harassment and cyberbullying. The collected tweets were filtered based on a compiled harassment lexicon, which contains a list of multi-dialectical profane words in Arabic compiled from four categories: sexual, racial, physical appearance, and intelligence. To annotate ArCybC, we asked five annotators to classify 4,505 tweets into two classes manually: Offensive/non-Offensive and CB/non-CB. We conducted a rigorous comparison of different machine learning approaches applied on ArCybC to detect Arabic CB using two language models: bag-of-words (BoW) and word embedding. The experiments showed that Support Vector Machine (SVM) with word embedding achieved an accuracy rate of 86.3% and an F1-score rate of 85%. The main challenges encountered during the ArCybC construction were the scarcity of freely available Arabic CB texts and the deficiency of annotating the texts.

The coronavirus disease , has caused a considerable increase in hospitalizations of people with different symptoms caused by this disease. Currently, the world needs a quick solution to tackle the further spread of COVID-19. Data mining techniques, machine learning and other artificial intelligence techniques can provide a best patient prognosis infected by coronavirus. This paper applies data mining techniques to predict COVID-19 infected patients' recovery using open dataset with day level information on COVID-19 affected cases of China. We also use minority Downsampling technique to balance the classes we have in the dataset and thus demonstrate the importance of balancing the classes to yield better results. Additionally, the pre-processing methods and the prediction performance using evaluation metrics are presented. Logistic Regression, Decision tree, and Neural Network algorithms are applied directly on the dataset using R programming language. Experimental results show that the neural network provides a lower error and increases the classification accuracy significantly compared with other algorithms.

This paper presents data stroke disease that combine exploratory data analysis and machine learning algorithms. Using exploratory data analysis we can found the patterns, anomaly, give assumptions using statistical and graphical method. Otherwise, machine learning algorithm can classify the dataset using model, and we can compare many model. EDA have showed the result if the age of patient was attacked stroke disease between 25 into 62 years old. Machine learning algorithm have showed the highest are Logistic Regression and Stochastic Gradient Descent around 94,61%. Overall, the model of machine learning can provide the best performed and accuracy.
