Keeping good news stories together: just part of what it means to work on Google News

Tuesday, May 13, 2008 8:23 PM



Have you noticed that when there are a bunch of articles about the same story, we’ll group them together? I think this is one of the key features of Google News. When you're browsing through Google News and you click on a link to see "all 257 articles" about a story, you can read perspectives from different news sources, or see how a story evolves over time.

We call these groupings of stories “clusters.” So far, we’ve only kept individual news stories together for three days, after which time they’re broken out and presented on their own.

Today, though, we’ve removed the three day limitation, meaning that stories will stay in clusters (and be easier to find) for as long as they're in our index. Since stories in Google News remain indexed for 30 days, you’ll find clusters for any news stories from the past month. Of course, this doesn’t mean that every article is going to appear in a cluster - just that clusters won’t be broken up anymore.

As an example, if you search for [dalai lama paris] in order to read about the decision of the city of Paris to make the Dalai Lama an honorary citizen, you'll get a story for that event along with related events:


In addition to greater perspective on news stories, this feature will also help us display more diverse search results on the first page: less space will be taken up by individual, unclustered articles. I think this brings us a step closer to our goal of making news universally accessible from as many sources, perspectives and languages as the world can offer.
