The most popular social news website, Digg, announced updating its dupe detection technology. This system is in charge with detecting duplicate entries and prevent their submission.
The developers teams made this upgrade after analyzing the types of duplicate entries submitted and concluding that most of these duplicates are actually the same stories coming from the same sites, but using different URLs.
They use a document similarity algorithm, comparing titles and descriptions with higher accuracy than before.
A change was also made at the submission process level, so that the system first matches the URL and then the description, unlike before, when you had to post the description of your story and wait for the duplicate checking.
In addition, you won’t have to wait that long for your story to be checked for duplicates. Now the process takes place in just a few seconds and only the first version of a story will be allowed on the social news website.
The dupe detection system seems to be close to perfection and eliminates the 30-day time interval after which anyone could start to post similar posts from the same website again.
Developers will continue keeping an eye on the submissions and see how the system responds to different tricks users might try to post their duplicates.
This announcement was posted on the official Digg blog by Chris Howard, Digg’s Director of Product.
