Constructing Colloquial Dataset for Persian Sentiment Analysis of Social Microblogs [PDF]
arXiv, 2023 Introduction: Microblogging websites have massed rich data sources for sentiment analysis and opinion mining. In this regard, sentiment classification has frequently proven inefficient because microblog posts typically lack syntactically consistent terms and representatives since users on these social networks do not like to write lengthy statements ...

Logistic approximations used to describe new outbreaks in the 2020 COVID-19 pandemic [PDF]
arXiv, 2020 In this investigation I used the Logistic Model to fit the COVID-19 pandemic data for some countries. The data modeled is the death numbers per day in China, Iran, Italy, South Korea, Spain and United States. Considering the current growth rate of the pandemic, it was possible to show that the death toll should be between 3,277-3,327 deaths in China, 2,
