Therefore, managing the network has become an increasingly a challenge given the existing network architectures. In this study, we have investigated how network operators operate, maintain and secure telecommunications networks. The study has also investigated the effectiveness of Software Defined Networking (SDN) in improving network management. The study has also investigated how the architecture minimizes the challenges users face. To improve network management with SDN using the OpenFlow protocol, we created network topologies and configured devices using the graphical network simulator 3, Oracle VM VirtualBox Manager, and Mininet VM. Our approach implemented both Git and Ansible in a centralized network architecture to solve the problems facing existing network architectures with the rapid growth of network-based devices on the Internet. This research paper has shown how to use Ansible playbooks to manage your network and overcome the challenges you face. The simulation results shows that the proposed scheme performs better in terms of efficiency and flexibility than the traditional OpenFlow protocol. These improvements have been achieved through the separation of the control and data planes, allowing for more centralized network management and easier implementation of network policies.","PeriodicalId":51314,"journal":{"name":"Big Data","volume":"33 1","pages":"1-5"},"PeriodicalIF":4.6,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87963992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Broadcast companies use Twitter to share short messages to engage or share opinions about a particular topic or product. With a large number of conversations available on Twitter, it is difficult to identify the category of topics in the broadcasting domain. This paper proposes the use of unsupervised learning to generate topics from unlabelled tweet data sets in the broadcasting domain using the latent Dirichlet allocation (LDA) method. Approximately six groups of topics were generated and each group was assigned a label or category. These labels were used to label the data by finding the dominating label in each tweet as the main category. Supervised learning was conducted to train six machine learning models which are multinomial logistic regression, XGBoost, decision trees, random forest, support vector machines, and multilayer perceptron (MLP). The models were able to learn from the data to predict the category of each tweet from the testing data. The models were evaluated using accuracy and the f1 score. Linear support vector machine and MLP obtained better classi-fication results compared to other trained models.","PeriodicalId":51314,"journal":{"name":"Big Data","volume":"61 1","pages":"1-6"},"PeriodicalIF":4.6,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74084993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a system for the management and monitoring of livestock on a farm using deep learning techniques. Traditional methods of monitoring livestock involve manual observation, which can be time-consuming and unreliable. Various systems have been developed, however, there are still challenges existing in present livestock classification and counting, including occlusion, animal overlapping, shadow, etc. To improve all these challenges, this paper presents a monitoring system of livestock under different conditions by the end-to-end deep learning model of You Only Look Once version 5 (YOLOv5). The suggested model conducts feature extraction on the original image with the original YOLOv5 backbone network and detects livestock of different sizes for counting on each anchor frame. Additionally, this model identifies and tracks individual animals The Kaggle dataset collected in real-time containing different animals is used as YOLOv5 relies heavily on data augmentation to improve its detection and tracking performance and validate the proposed system. The scaling, resizing, and manipulation of the splitting dataset are done by the Roboflow application. Additionally, this paper seeks to demonstrate the latest research in utilizing Faster Regional convolutional neural networks (R-CNN) and compare its backbones with the original YOLOv5 backbone. The tensor board graphs from Colab show that this proposed system outperformed other R-CNN, achieving an accuracy of 93% on mAP@_0.5%, making it a promising option for intelligent farm monitoring and managing.","PeriodicalId":51314,"journal":{"name":"Big Data","volume":"6 1","pages":"1-6"},"PeriodicalIF":4.6,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79674554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Educational stakeholders continue investigating diverse solutions to improve student learning behaviour in higher educational institutions. One solution that stands out is to gain insights and identify the trends and patterns in data about students learning behaviour for decision-making. Exploratory Data Analysis (EDA) is a method for analysing and summarising data in order to get insights and recognise patterns or trends about an entity. This study seeks to utilise Exploratory Data Analysis to analyse students' logs in the virtual learning environment to distinguish the characteristics/habits of students who graduate and students who do not graduate from higher educational institutions. The process flow for implementing EDA can act as a helpful guide for educational stakeholders. The study findings indicate that the revision trend of graduated students is much more frequent than that of non-graduated students. However, there were no differences in habits in the early access to the learning materials before the start of the program. Academic stakeholders can utilise the approach to enable them to make better decisions when assessing students' behaviour and trends in the virtual environment.","PeriodicalId":51314,"journal":{"name":"Big Data","volume":"187 1","pages":"1-8"},"PeriodicalIF":4.6,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80670616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can infect domestic and wild pigs, causing severe economic and production losses. The virus can be spread through live or dead pigs and through pork products. Since there is currently no vaccine or treatment method, it poses a major challenge and threat to the pig industry once it breaks out. The results of the investigation show that most existing solutions use laboratory tests to diagnose possible ASF cases. In addition, various machine learning (ML) techniques have been used in the past to diagnose ASF. However, historical review of recent years shows that laboratories have difficulty diagnosing ASF with the required accuracy due to a lack of correlation between causes and effects. Lack of accuracy and incorrect ASF diagnoses by laboratories have proven to be a major problem for pig welfare. Consequently, misdiagnosis of ASF disease can result in severe direct and indirect economic losses to farmers, especially farmers whose income is derived primarily from pig production. While several other researchers have proposed the use of ML for ASF diagnosis, the application of cause-effect relationships between specific viruses and symptoms for ASF diagnosis is still missing. In this systematic literature review, we examine the methods, limitations, and approaches in the existing literature from ML and laboratories for ASF diagnosis. In this review, we evaluate the performance of ML and laboratory techniques for ASF diagnosis. In addition, we compare the performance of the techniques of ML with other statistical approaches such as causal ML and computer vision for ASF diagnosis. In addition, the strengths and weaknesses of ML and laboratory techniques for ASF diagnosis were summarized. A thorough search of relevant databases was performed, and the selected studies were examined using predefined inclusion and exclusion criteria. Nevertheless, the study also indicates an area for improvement, such as the accuracy of ASF diagnosis. The study recommends the use of Causal Reasoning with ML to develop a causal ML model capable of establishing relationships between viruses and symptoms to improve the accuracy of the ASF disease. The application of causal ML is presented as an alternative solution for laboratory diagnosis of ASF, which contributes to the field of the study. In addition, further research could investigate the possible characteristics of ASF, including virus variants originating from the ASF family. The review could provide essential information on ASF datasets based on the interpretation of results obtained from the use of appropriate samples and validated tests in combination with the information from laboratory tests of ASF disease epidemiology, scenario, clinical signs, and lesions produced by different virulence.

To this end, software-defined networking (SDN) was introduced to provide network operators with the infrastructure for achieving greater flexibility and fine-grained control over networks. However, a critical issue to consider when incorporating SDN technology over large-scale networks like wide area networks (WANs) is the allocation of switches to controllers. In this paper, we address the switch-to-controller allocation problem that considers the heterogeneity of controller capacities. Specifically, we propose two neighbourhood centrality-based algorithms for addressing the problem with the aim of minimizing switch-to-controller latency. We also introduce a weighted centrality function that enables fair distribution of load across capacitated controllers. The proposed algorithms utilize centrality-based measures and heuristics to determine the ideal switch-to-controller allocations that consider the propagating capacity of suitable controller nodes. We evaluate the performance of the proposed algorithms on the internet2 topology. The results show that considering the heterogeneity of controller capacities reduces load imbalance significantly. Moreover, by limiting the exploration of the local centrality for each node to a maximum of two-step neighbours the complexity of the proposed algorithm is reduced. Thus, making it suitable for implementation in real-world SD-WANs.","PeriodicalId":51314,"journal":{"name":"Big Data","volume":"1 1","pages":"1-6"},"PeriodicalIF":4.6,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76735105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The South African retail industry is expected to upgrade its systems and advance to technologically advanced retail systems, which have already been implemented in various countries globally. With the implementation of loT technologies around the world, South African retailers are expected to follow suit with the new changes and face the challenges that may arise as a result of the implementation. loT technologies through digital transformation have been portrayed worldwide as an advantageous practice and competition-leveraging tool to promote business agility and capabilities, improve business processes, and, ultimately, enhance customer satisfaction. The purpose of this paper is to assess the level of readiness of the South African retail industry when it comes to moving away from a conventional functional system to a system mainly dominated by advanced technology-based practices.
