It is worth noting that the fraction of tweets on topic 2 (distance learning concerns) increases considerably from 16.95% in the first period to 45.94% in the last period. In Brazil, in 2019, the emission of greenhouse gases from freight transport corresponds to 25% of the emission of gases from the energy sector, that is, 5.25% (25% x 21%) of the greenhouse gases . Emotional recognition aims to identify the emotions that a tweet carries. Sadness is considered by numerous authors to be a core symptom of depression42.

Put 1.5 - 2 seconds between each rider in staggered formation (not the 1 second recommended in many rider training courses). In addition, because the velocity is constant 213 at 3, we know that if3 s (t) = 3t, then s 0 (t) = 3, so s (t) = 3t is . To clean the data and prepare it for sentiment analysis, we applied the following preprocessing steps using NLP techniques implemented with Python: replaced HTML characters with Unicode equivalent (such as replacing & with &).

To explore what the user is concerned about on Twitter with reference to distance learning, we applied LDA to our clean corpus. The latent Dirichlet allocation (LDA) model is one of the most popular topic modeling methods; it is a probabilistic model for expressing a corpus based on a three-level hierarchical Bayesian model. The use of digital teaching technologies accelerated and led to a hybrid instructional model that combined remote and face-to-face teaching, named integrated digital learning. 4) for all regions except for Umbria (\(+\) 0.10), Sardinia (\(+\) 0.07) and Veneto ( 0.06), which slightly exceed the neutrality thresholds. Formalist and structuralist theorists tend to emphasize a predictable relationship between the reader and the language of literature because individual readers, as Roland Barthes has pointed out, "cannot by [themselves] either create or modify . To solve for distance use the formula for distance d = st, or distance equals speed times time. Google Scholar. What are the three action .
