  Many COVID-19 patients developed prolonged symptoms after the infection,
including fatigue, delirium, and headache. The long-term health impact of these
conditions is still not clear. It is necessary to develop a way to follow up
with these patients for monitoring their health status to support timely
intervention and treatment. In the lack of sufficient human resources to follow
up with patients, we propose a novel smart chatbot solution backed with machine
learning to collect information (i.e., generating digital diary) in a
personalized manner. In this article, we describe the design framework and
components of our prototype.
