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 below line-chart. I only need to do deep analysis from May 17 to May 20.  |
|
3. Find out the affected areas The symptom words used on May 18 are related to aches, breath, chills, cough, fatigue and sweats. These symptoms outbroke mainly in Uptown, Downtown and Eastside.  |
