User:Staeckerbot

From Wikipedia, the free encyclopedia

This is the userpage of an inactive bot which was operated by User:Staecker from April 2007 to May 2008.

This bot's main function will be to place speedy-delete tags on duplicate image uploads.

See my request for approval, concluded April 8, 2007.

Details[edit]

The bot runs every 15 minutes and scans Special:Newimages. At the first pass, the bot just checks for uploads with identical filesizes. Any files with identical sizes have their thumbnails downloaded and compared directly (using PIL).

  • If the thumbnails are identical and the description page has no previous file history, then:
  • If the thumbnails differ or the description page has a file fistory, then the images are logged to User:Staeckerbot/Suspicious images, to be handled by a human editor. I have found that most such cases do represent duplicate images, perhaps with different metadata or other differences invisible to the eye.

The bot is built on the pywikipedia framework, and runs on ubuntu linux.

There are a few minor issues that I don't really have the time to work out: see User:Staeckerbot/Known bugs.

I welcome any comments or suggestions you have on improving the bot- Staecker

Logs[edit]

  • User:Staeckerbot/Suspicious images Images which were uploaded closely together and have the same file size, but differ as binary files. Many of these may be duplicate images, but need to be checked by hand.
