Bush. Energy. Oil. Caribbean? These were the most frequently uttered words in Congress last week, brought to you courtesy of Sunlight’s latest Web site, Capitol Words. Now, you can have an at-a-glance view into the daily proceedings of the United States Congress through the simplest lens available — a single word.

For every day that Congress is in session, Capitol Words displays the most frequently used word in the Congressional Record, dating back to the second session of the 106th Congress (January 20, 2000). (The Congressional Record, published daily, is a complete account of the floor proceedings of the House and Senate.)

We created Capitol Words to make it easy to know what issues Congress is addressing on a daily basis. Whether the congressional word of the day matches up to an issue, an action or the name of a member of Congress, Capitol Words provides a snapshot of the main topic addressed by Congress for any given day. By looking at the site’s calendar view, it’s obvious that ‘energy’ has been a hot topic in Congress this month.

Capitol Words is powered by LOUIS which scraped the Congressional Record on GPO Access. Our Labs also created an API so you can incorporate the word of the day in your applications.
