Analysing the sentiments about the education system trough Twitter
Abstract: This paper applies Information and Communication Technologies (ICT) as well as
data analysis to gain a better understanding of the existing perception on the education
system. 45,278 tweets were downloaded and processed. Using a lexicon-based
approach, examining the most frequently used words, and estimating similarities
between terms, we detected that a predominantly negative perception of the education
system exists in most of the analysed countries. A positive perception is identified in
certain low-income nations. Men exhibit a more positive sentiment than women as
well as a higher subjectivity in some countries. The countries that exhibit the most
positive perceptions India, Canada, Pakistan, Australia, South Africa and Kenya are
also those that manifest the highest subjectivity.
