5.3.1 Nomophobia case study:
In this section, we delve into the rise of nomophobia-a concern that is becoming increasingly prevalent in our digital era. We will examine how natural language processing (NLP) and machine learning (ML) technologies can be utilized to recognize these fears. Through this exploration, we shed light on approaches to comprehending and supporting individuals who struggle with phobias in the 21st century.
5.3.1.1 Introduction:
Nomophobia, a term derived from "no mobile phone phobia," is becoming a growing issue that highlights a reliance on mobile phones. A notable study by Vaishnavi Visweswaraiah et al. explored the impact of nomophobia before and after the COVID-19 pandemic, utilizing social media data from Twitter to gain insights into how expressions of dependency on phones have changed during this time period. [10].
5.3.1.2 Methodology:
The study examined tweets from February 2020, before the COVID-19 pandemic, and May 2020, during the COVID-19 era. There are two stages in this study: 1) To determine if tweets were related to nomophobia or not, a relevancy classifier was built using machine learning algorithms such as regression, naïve Bayes, and support vector machine. Among these classifiers, logistic regression (LR) showed effectiveness in identifying tweets. 2) Topic modeling using Latent Dirichlet Allocation (LDA) on nomophobia-relevant tweets classified by the LR model [10].
5.3.1.3 Findings:
The analysis, facilitated by the Latent Dirichlet Allocation (LDA) algorithm, revealed the existence of prominent themes in expressions of nomophobia. Before the pandemic, the primary themes included 'Addiction to Digital Entertainment' and frustrations due to 'Bad Internet Service.' However, during the COVID-era, the expressions transformed to include 'Work from Home Difficulties' and 'Extreme Attachment to Digital Technology' during quarantine [10].
