Collaborative Information Ranking

 

Description

Allows ranking of items (photos, news articles) by many users, highlighting those items that users find interesting or useful.  The most familiar use of this capability is by Amazon.com.

Uses and Potential Benefits

Allows users on the web to determine the content that is most useful and relevant to them, and display that most prominently.  Example: a foundation might provide a news feed on their website that allows users to mark articles they found most useful, allowing those to rise to the top of a list.
