How this youtube application works??

Recommended Posts

Hello,

 

I was just wondering that how youtube 's "Recommended for you" logic works. like it checked all the urls /videos you have watched last time(logged in time) and next time when users logs in, it ll show him/her the related those videos(probably most popular)  he/she had watched earlier.

 

i was just wanted to know its rough idea that how it works.

 

Can anyone tell me how it works?

 

Thanks in advance.

Chances are that they're also recording which other videos other people came from (or went to) for videos you recently watched. Those can then be ranked and act as part of the recommendation engine.  Whether that's the case or not, I'd recon the system in place on YouTube is pretty complex and non-trivial to recreate.

Thanks for the reply to both of you.

 

Yes i was thinking something similar like if i can check the categories of what user has seen the videos before so i can store them and next time show them the most recent videos belong to that particular category.

 

Anyways i  have got the logic.

 

Thank you.
