ABSTRACT
To minimize the pace of transmission of the novel Covid-19 virus, institutions have shifted to e-learning to substitute lectures and assessments in the classroom without being fully ready and technologically equipped. As a result, institutions must identify and employ the most suitable data architecture for their universities. For this purpose, this study first identifies 109 e-learning solution use cases, collects their 983 user reviews from the e-learning industry, and categorizes them according to their data architectures for appropriate comparison using the developed conceptual framework. The finding shows that data-driven and data-centric were the only architectures used by e-learning solutions, it further recommends data-centric as the best suited for e-learning. © 2022 IEEE.
ABSTRACT
The emergence of the COVID-19 pandemic has led to an unprecedented change in the lifestyle routines of millions of people. Beyond the multiple repercussions of the pandemic, we are also facing significant challenges in the population's mental health and health programs. Typical techniques to measure the population's mental health are semiautomatic. Social media allow us to know habits and daily life, making this data a rich silo for understanding emotional and mental well-being. This study aims to build a resilient and flexible system that allows us to track and measure the sentiment changes of a given population, in our case, the Mexican people, in response to the COVID-19 pandemic. We built an extensive data system utilizing modern cloud-based serverless architectures to analyze 760,064,879 public domain tweets collected from a public access repository to examine the collective shifts in the general mood about the pandemic evolution, news cycles, and governmental policies using open sentiment analysis tools. We provide metrics, advantages, and challenges of developing serverless cloud-based architectures for a natural language processing project of a large magnitude. © 2022, The Author(s).
ABSTRACT
The COVID-19 pandemic has had an impact on many aspects of society in recent years. The ever-increasing number of daily cases and deaths makes people apprehensive about leaving their homes without a mask or going to crowded places for fear of becoming infected, especially when vaccination was not available. People were expected to respect confinement rules and have their public events cancelled as more restrictions were imposed. As a result of the pandemic's insecurity and instability, people became more at ease at home, increasing their desire to stay at home. The present research focuses on studying the impact of the COVID-19 pandemic on the desire to stay at home and which metrics have a greater influence on this topic, using Big Data tools. It was possible to understand how the number of new cases and deaths influenced the desire to stay at home, as well as how the increase in vaccinations influenced it. Moreover, investigated how gatherings and confinement restrictions affected people's desire to stay at home. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
