Video About Wolfram Alpha

I just finished to watch the introductory video about Wolfram Alpha

It mainly explained the main feature of the website and their main challenges in how to implement it.

I also liked the break down of their challenge:

1. Data Acquisition
2. Data Curation
3. Linguistic Curation
4. Dynamic Visualization

or as I translate;

1. Get the information
2. Extract the Good Information
3. Make it understandable
4. Make it attractive
