Nowadays, consumers prioritize e-shopping over the brick and motor stores due to numerous benefits, including time and transport convenience. However, this progressive upsurge in online payment increases the number of credit card frauds. Therefore, defending against fraudsters’ activity is obligatory and can be achieved by securing credit card transactions. The objective of this paper is to build a model for credit card fraud detection using Machine learning techniques. An innovative approach to credit card fraud detection grounded on machine learning is proposed in this study. Machine learning (ML) is an artificial intelligence subfield comprising learning techniques from experience and completing tasks without being explicitly programmed. Three ML techniques have been used: Support vector machine, logistic regression, Random Forest, and Artificial Neural network. First, the most significant features that affect the type of transaction (fraud or not fraud) have been selected. After that, the ML model was applied. The performance of the proposed approach is tested using a confusion matrix, recall, precision, f-measure, and accuracy. The proposed method is tested using accurate data that consists of 284807 transactions. The result shows the efficiency of the proposed approach.","PeriodicalId":417206,"journal":{"name":"Journal of Computer Science and Technology Studies","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127324224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The news algorithm recommendation mechanism can effectively meet the preferences and needs of users, maximize the cohesion between media and users, and ensure that the number of customers will not be lost in business operations. However, the news algorithm recommendation mechanism also has many problems of its own. This article analyzes it from the following multiple angles. First of all, starting from the theory of agenda setting in the field of news communication, it can be concluded that agenda setting under the news algorithm recommendation mechanism is partially invalid, but the mainstream media can still take on the role of replacement. Secondly, it analyzes the two aspects of information rights and privacy rights from the perspective of law and interprets the legal effect of news algorithm recommendation from two different normative paths. Finally, through sociological discussion of technology ethics, it is necessary to establish a more unified social norm to deal with various ethical crises that technology may bring.","PeriodicalId":417206,"journal":{"name":"Journal of Computer Science and Technology Studies","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131714973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sample of the study consisted of (84) employees in the monitoring of health services and its combined clinics in the municipality of Kufra, Libya who were randomly selected. The results revealed that the paramount importance in the success of these systems is the human resources used for these systems more than software and hardware. The results also indicated that the electronic archiving system has a positive impact in the field of administrative work, by facilitating the archiving of documents to reduce the time and effort expended in the process of searching for files, and the ease of sharing documents through a network based on (client / server) to link health services control departments and grouped clinics. In the light of the results of the study, the researchers recommended the need to focus on identifying the increase in the commitment of the Kufrah health services monitor to move towards electronic archiving. They also recommended the importance of training employees on automated documentation and electronic archiving processes, with the dissemination of the electronic archiving experience among government agencies and auditors as a starting point for the application of e-government.","PeriodicalId":417206,"journal":{"name":"Journal of Computer Science and Technology Studies","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129749610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The determination of the major aims to make students more directed in receiving lessons based on the abilities and talents of the students, and, of course, when the student graduates, they already have the skills to get a job if they do not continue their education to college. The method used in this study is data mining techniques. But not all data mining algorithms perform well in classifying the selection of interest paths at the SMK level. Therefore, this study will discuss the comparative analysis of the performance level of the Support Vector Machine (SVM) classification algorithm and the Naïve Bayes Classifier (NBC) and K-Nearest Neighbors (KNN). Comparison of NBC, KNN and SVM methods was measured using feeding accuracy for the KNN method to get an accuracy of 54.56%, then for the NBC method to get an accuracy of 74.78%, and the SVM method to get an accuracy of 58.70%. Then it can be concluded that the three methods, based on the attributes used by the NBC method, got high accuracy, which is 74.78%.","PeriodicalId":417206,"journal":{"name":"Journal of Computer Science and Technology Studies","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123958744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to regular times, E-learning during the COVID-19 pandemic depends on available home resources. Technology plays an essential role in supporting the implementation of e-learning which must consider the resources available at home. This research is a systematic literature review using database sources from ScienceDirect and Emerald. The inclusion criteria are research that discusses e-learning in higher education during the COVID-19 pandemic (2019-2020) from a computer science perspective. An exclusion criterion is research examining e-learning in higher education from sources outside ScienceDirect. The search results from ScienceDirect obtained 518, and Emerald got 66 relevant articles. The next stage is reviewing abstracts and titles that focus on technology in e-learning on the lecturer and student side; We obtained 23 articles and then checked them in full text. This literature study shows that technology as a support for e-learning systems during the COVID-19 period in universities needs to consider the resources available at home, namely infrastructure and applications for students and teachers, for future work in the research of friendly e-learning technology to the availability of resources at home.","PeriodicalId":417206,"journal":{"name":"Journal of Computer Science and Technology Studies","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114984279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
