Vinyl & Data

Time to bring two topics together: finding promising releases for fixing and image processing. The first topic I wrote about in this post , the second topic I wrote about in a series of posts, ending with a large test of images of a specific Spanish label . I specifically focused on cherry picking the releases with 1 image to see if that image contained a label. I found 1299 releases with 1 image for this label and compared it with the releases that I found a label for. The results were, as expected, very poor: for only 9 releases with 1 image the image was actually a label. Of these a few already had the right depósito legal information on the release page (and I hadn't filtered for that this time), some had already been updated and others didn't show the label with the depósito legal information on it, but the label of the other side. Still I would consider this a resounding success, because now I don't have to look at the 1290 other releases, but can very efficient...

So far these blogs have been about detecting wrong information in releases that people entered into the database, but there are also other errors that are much harder to find, namely detecting if a release is missing information and are incomplete. Many releases in Discogs are missing information. One of the things we did for a while was track new Spanish that were added, looking at the pictures (if any) and then adding the missing information, such as the depósito legal, or a rights society. But this does not scale, and it is also quite labour intensive, and it is not easy to remember by heart which releases have already been checked. So I want to optimize to success: which releases will likely be the easiest to fix? I ran a test, where I confined my search to: releases from Spain 7" releases (vinyl, flexi-disc) with the specific goal to fill in the depósito legal field(s) and other things like rights society fields (if not already there). The following was done: first...
