Web search presentation

In the lecture, Chris presented how Google navigates the web, raised the problem of "filter bubble" and offered us tips on efficient search.

Google navigates the web by over two hundred factors, but most importantly, the result ranking depends on the quality of a webpage. Google decides the quality depending on the frequency that a particular page is linked to other sites.

Google, Facebook and other most popular websites conduct the personalized editing based on our browse history and many other astonishing details, such as where we sit and the computer we use. Such personalized editing is termed as "Filter bubble", which causes us to see only the things we want to see instead of what we should see objectively.

At last, he offered the tip on selecting the key words. For example, we could filter the result by adding "site: .edu" or "-site:.com", or using the word that sounds more academic-related.

Chris shared abundant information and all of them are very interesting. I was greatly benefited. Thank you Chris.
