Data in Africa

Common challenges – Accessibility/ Availability and Quality

How can we discover data and surface

information?

– How does Facebook and Amazon suggest friends you may know and recommended items to purchase?

– How can we solve the never ending traffic problems in the city?

– How does NYC determine the frequency of

subway trains all day; all weekend?

What is Data Science?

The process of using data to surface information and tell stories Data Science includes collecting data, cleaning and managing the data, making it tell its story, and presenting that story to others

An ideal Data Scientist is: 1/3 part Mathematician 1/3 part Computer Scientist 1/3 part Artist

How can we innovate in each of these processes?

Data Collection

•  Survey management processes: – Mobile and web data

collections tools

– Open Data Portals – Crowdsourcing tools

KODI

Data Storage

•  Data Storage/Warehousing:

–  MySQL; NoSQL; SparQL; Linked Data; Azure; Amazon Cloud Services; Dropbox

–  What formats is the data stored in?

–  Data Cleaning processes – Need tools such as Google

Refine?
