In a move to curb information overload, MSN Newsbot is set to use implicit customization to help users find news important to them. The idea is similar to Google News, which scans over 4000 news sources, and clusters similar articles together by topic.
Newsbot goes one step further, and considers which stories the user has chosen to read to present new stories as they appeal to the user. While Microsoft hasn’t revealed its technology, it’s likely a cross between Google News and Amazon.com.
Amazon analyses user preferences, and if it determines you have similar tastes to a certain group of people, then it recommends other books those people have liked.
