Question 1

1. Filter keywords from Microblogs texting

I chose observed symptoms as keywords to filter out related Microblogs by using JMP. The observed symptoms contain chills, sweats, aches and pains, fatigue, coughing, breathing difficulty, nausea and vomiting, diarrhea, and enlarged lymph nodes. I use the symptom-related keywords and frequency of these words to improve accuracy.

2. Find out the outbreak time

We can find all the symptoms are sharply increased from May 18 and partial from May 19 in Figure1 line-chart. I only need to do deep analysis from May 17 to May 20.
