AI Article Synopsis
- Using a combination of disease ontology, text mining, and statistical analysis, researchers compiled a list of COVID-19 symptoms to build a foundation for analysis.
- By employing machine learning techniques on Google search and Twitter data, they created a long-short-term memory (LSTM) model that effectively predicted increases in confirmed cases and hospitalizations up to 14 days in advance, achieving high accuracy scores.
Article Abstract
The COVID-19 pandemic has pointed out the need for new technical approaches to increase the preparedness of healthcare systems. One important measure is to develop innovative early warning systems. Along those lines, we first compiled a corpus of relevant COVID-19 related symptoms with the help of a disease ontology, text mining and statistical analysis. Subsequently, we applied statistical and machine learning (ML) techniques to time series data of symptom related Google searches and tweets spanning the time period from March 2020 to June 2022. In conclusion, we found that a long-short-term memory (LSTM) jointly trained on COVID-19 symptoms related Google Trends and Twitter data was able to accurately forecast up-trends in classical surveillance data (confirmed cases and hospitalization rates) 14 days ahead. In both cases, F1 scores were above 98% and 97%, respectively, hence demonstrating the potential of using digital traces for building an early alert system for pandemics in Germany.
