Objective & Methodology
In light of the serious situation that Smartpolis faces (several deaths reported!), I need to:
1. Source: Determine origin of disease outbreak
2. Spread: Find out medium of transmission
3. Control: Suggest measures to contain spread
My approach to this problem is:
Action Step | Result |
---|---|
Filter blog text for spots of flu | Exclude non-disease blogs from analysis |
Determine type of symptoms | Categorise symptoms into water, air or human |
Correlate spots with map and time | Animate disease outbreak path by timelapse |
Drill down into water-borne | Study the origin, spread and contributing factor |
Drill down into air-borne | Study the origin, spread and contributing factor |
Drill down into human-transmitted | Study the origin, spread and contributing factor |
So that I can suggest containment measures and geo-fencing for each of the transmission type.
Data Preparation
Efforts are needed to transform the "Microblog" dataset into a format that is conducive for visualization.
Variable | Treatment | Description | Screenshot |
---|---|---|---|
Location | Break into "Lat" and "Lon" respectively | SAS EG workflow to prepare Lat/Lon and save to library | |
Text | Find stemmed words from text | SAS EM workflow to extract stemmed words from library | |
Text | Filter microblogs to only pre-defined symptoms | SAS EG workflow to join documents and words list | |
Adhoc | Transformation as necessary | Tableau | Visualization tricks |
