WEEK 12

 Hi All,

I hope all of you have had a good week. My research will be done next week. By that time, I would have a solid result to analyze and share with you all. Currently, I have gathered data for the same input, “how to make a pizza” from the original and new method. The results are pretty interesting.

Here is the table from the original method.

Inputs	Before / After	Number of videos	Percentage
How to make a pizza	Before	0	0 %
	After	118	98.33 %

Here is the table from the new method.

Inputs	Before / After	Number of videos	Percentage
How to make a pizza	Before	20	16.66 %
	After	109	90.83 %

Before searching, the rate of relevant videos increased roughly by 17%. After searching, the rate of relevant videos decreased about by 8%. From this result, my question is, why has it decreased after searching? One of my assumptions is that YouTube may suggest few other videos which are not relevant to the input to figure out my preference and behaviors based on my view time and videos I clicked. It is good to have progress on this.
