Query: #StayHome or #Marathon? Social Media Enhanced Pandemic Surveillance on
  Spatial-temporal Dynamic Graphs   COVID-19 has caused lasting damage to almost every domain in public health,
society, and economy. To monitor the pandemic trend, existing studies rely on
the aggregation of traditional statistical models and epidemic spread theory.
In other words, historical statistics of COVID-19, as well as the population
mobility data, become the essential knowledge for monitoring the pandemic
trend. However, these solutions can barely provide precise prediction and
satisfactory explanations on the long-term disease surveillance while the
ubiquitous social media resources can be the key enabler for solving this
problem. For example, serious discussions may occur on social media before and
after some breaking events take place. These events, such as marathon and
parade, may impact the spread of the virus. To take advantage of the social
media data, we propose a novel framework, Social Media enhAnced pandemic
suRveillance Technique (SMART), which is composed of two modules: (i)
information extraction module to construct heterogeneous knowledge graphs based
on the extracted events and relationships among them; (ii) time series
prediction module to provide both short-term and long-term forecasts of the
confirmed cases and fatality at the state-level in the United States and to
discover risk factors for COVID-19 interventions. Extensive experiments show
that our method largely outperforms the state-of-the-art baselines by 7.3% and
7.4% in confirmed case/fatality prediction, respectively.
