Timeline of Articles from a Google News Cluster

Google News enhanced the presentation for the clusters of related articles: after showing options to filter the articles, a search option and feeds, Google News added a graph that shows the number of sources covering the story. There's also a timeline that lets you understand how the story developed.

"Our grouping technology takes into account many factors, such as titles, text, and publication time. We then use various clustering algorithms to identify stories we think are closely related," explains the help center.


  1. Worth noting that it only works on certain (I suppose larger) clusters. Here's an example link.

  2. doesn't work on sports cluster as well.

  3. So when is Google going to apply the clustering to Google Reader? I would love to only read the most popular article on a given topic with links to others when a big story hits because several of my feeds have overlapping content.

  4. @Matthew Kolb: Totally agreed.
