ArCovidVac: Analyzing Arabic Tweets About COVID-19 Vaccination
This work addresses the problem of misinformation and public sentiment analysis for policymakers and researchers during the COVID-19 infodemic, though it is incremental as it focuses on dataset creation and benchmarking.
The authors tackled the challenge of identifying and analyzing COVID-19 vaccination-related information in Arabic tweets by creating ArCovidVac, the first largest manually annotated dataset for this purpose, which includes annotations for informativeness, content types, and stance, and they benchmarked it using transformer architectures.
The emergence of the COVID-19 pandemic and the first global infodemic have changed our lives in many different ways. We relied on social media to get the latest information about the COVID-19 pandemic and at the same time to disseminate information. The content in social media consisted not only health related advises, plans, and informative news from policy makers, but also contains conspiracies and rumors. It became important to identify such information as soon as they are posted to make actionable decisions (e.g., debunking rumors, or taking certain measures for traveling). To address this challenge, we develop and publicly release the first largest manually annotated Arabic tweet dataset, ArCovidVac, for the COVID-19 vaccination campaign, covering many countries in the Arab region. The dataset is enriched with different layers of annotation, including, (i) Informativeness (more vs. less importance of the tweets); (ii) fine-grained tweet content types (e.g., advice, rumors, restriction, authenticate news/information); and (iii) stance towards vaccination (pro-vaccination, neutral, anti-vaccination). Further, we performed in-depth analysis of the data, exploring the popularity of different vaccines, trending hashtags, topics and presence of offensiveness in the tweets. We studied the data for individual types of tweets and temporal changes in stance towards vaccine. We benchmarked the ArCovidVac dataset using transformer architectures for informativeness, content types, and stance detection.
