Here is an interesting filter service.

10×10™ (‘ten by ten’) is an interactive exploration of the words and pictures that define the time. The result is an often moving, sometimes shocking, occasionally frivolous, but always fitting snapshot of our world. Every hour, 10×10 collects the 100 words and pictures that matter most on a global scale, and presents them as a single image, taken to encapsulate that moment in time. Over the course of days, months, and years, 10×10 leaves a trail of these hourly statements which, stitched together side by side, form a continuous patchwork tapestry of human life.

10×10 is ever-changing, ever-growing, quietly observing the ways in which we live. It records our wars and crises, our triumphs and tragedies, our mistakes and milestones. When we make history, or at least the headlines, 10×10 takes note and remembers.

How does it work?

Every hour, 10×10 scans the RSS feeds of several leading international news sources, and performs an elaborate process of weighted linguistic analysis on the text contained in their top news stories. After this process, conclusions are automatically drawn about the hour’s most important words. The top 100 words are chosen, along with 100 corresponding images, culled from the source news stories. At the end of each day, month, and year, 10×10 looks back through its archives to conclude the top 100 words for the given time period. In this way, a constantly evolving record of our world is formed, based on prominent world events, without any human input.
