A dynamic latent Dirichlet allocation model (DLDA) was built to identify commonly discussed topics in tweets and their evolution over time. J. La Rosa, V. L., Gori, A., Faraci, P., Vicario, C. M. & Craparo, G. Traumatic distress, alexithymia, dissociation, and risk of addiction during the first wave of COVID-19 in Italy: Results from a cross-sectional online survey on a non-clinical adult sample. 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 &). The first is a measure based on a sliding window that uses normalized pointwise mutual information (NPMI) and cosine similarity. Average speed is a scalar, so we do not include direction in the answer. The COVID-19 pandemic has greatly affected life worldwide. Why does a motorcycle have an engine cut-off switch? Fourth Int.

Through extensive human work, this tool enables the sentiment analysis of social media to be completed quickly and has a very high accuracy similar to that of human beings. In the subsequent months, distance learning gradually moved to integrated digital learning3, which combined remote (virtual classroom) and in-person (traditional classroom) instruction. This is rather convenient when you want to know how far it is between each degree, no matter where you are on Earth. D. Article However, the distance learning topic truly affects the younger population more closely than the older population; therefore, the underestimation issue may have a marginal, if any, impact on the results in the present study.

The 4-second rule is an estimate of A. the vehicle's braking distance. In the past, it was often suggested that you keep one car length of safety distance for every 10 mph of speed. The Russian conquest of Central Asia was the 19th century's most dramatic and successful example of European imperial expansion, adding 1.5 million square miles of territory and at least 6 million people - most of them Muslims - to the Tsar's domains. Thus, when car A is 3 blocks north of the intersection and car B is 4 blocks east of the intersection, the distance between them is decreasing at a rate of 2 mph. Regarding the emotion analysis, a possible limitation is that the number of emotion categories was limited to 828,44, but emotion is a broad concept and may involve up to 27 categories45.

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 . ("One Thousand One, One Thousand Two," etc.) Findings from this study could help the Ministry of Education visualize how people are coping with distance learning, thus improving distance learning support and making the experience more effective in the future. 4 seconds is proven to be the adequate distance to prevent crashes, contradicting previous estimates of 2-3 seconds. Asare, A. O., Yap, R., Truong, N. & Sarpong, E. O.
