Auto-rejection of artworks

August 30th, 2006 in New Features

Sick of really bad quality snapshots in the public gallery? Us too!

From now on, snapshots that have less than a certain rating and sufficient votes will be auto-rejected.

Certain rating you say? At the time of writing, we’ve set this cutoff value at 35%. This is the normalised rating as shown in the artwork detail view.

Sufficient votes? Since our artwork rating and gallery ranking system uses the Bayes Theorem, each artwork needs a sufficient amount of votes so that the rating reaches a certain believability (or certainty) threshold. At the time of writing, we’ve set this value to 25 votes.

So, once a snapshot “goes south” and has a enough votes, it will auto-disappear, ie it will be placed back in your private snapshots gallery.

Why are there still some snapshots around that don’t disappear even though they should be eligible for auto-reject death? That’s because we’ve been sneaky and have marked some snapshots to be immune to auto-rejection, for various reasons. :-)

Great Idea! I like this article a lot. It was very helpful! I’m sick of viewing artwork that was not completed at all yet made it to the Gallery. So, this nifty little feature will ease our eyes and hopefully, bring some more professional/beautiful artwork to the spotlight.

I wanted to know something. Say, for example not everyone voted on your particular artwork to keep it from disappearing. Is there a way of saving artwork to your “Private Snapshots” and keeping there without depending on votes? I’m assuming the answer is , “Yes.”

Every artworks needs 25 votes before it can become auto-rejected. Auto-rejection doesn’t delete an artwork, it just places it back in your private snapshots gallery.

how long do the artworks stay around in order to gain these 25 votes? i imagine if it was too short a period of time then some really good artworks would not get a chance becuase not enough users had gone through the gallery to view new images.

what about comments.. do they count into this at all? there are some artworks that have few votes but many comments. will these get taken out automatically despite the fact that they have started converstations amoungst the members?

do - and + votes count or does it just count 25 + votes?

They stay around forever, if this is how long it takes. The whole point here is that if an artwork is below a certain limit in terms of quality, as determined by its rating, then it will be automatically rejected, but only if it has enough votes so that we have a high enough certainty that the artwork is really of low quality. That’s what that 25 vote counts refers to - that’s 25 votes in total, whether plus or minus.

Comments have nothing to with the rating of an artwork.

so put simply if the majority of the 25 votes are + it is kept and if the majority are - it is rejected?

Markus24 Sep 06

Wonderful goose: No. I’ll try to explain again. All new artworks start off with average rating. As more and more votes are being cast, the rating of the artwork will either get higher or lower.

If an artwork is bad and its rating falls and falls until it is lower than a certain cutoff rating, then it is rejected if it has at least 25 votes.

Well, keeping the artwork until 25 votes has been accumulated would cause some artworks to hang around for long time. I think there could be another factor that would control the time it takes to get that certain amount of votings.

But then again, I think to judge something creative by opinions of only 25 people is still too low. Did you take 25 cause after 25/30 samples u can assume it to be Normally Distributed?? I mean, that must be the statistical base.

Markus26 Sep 06

I’m explaining the same thing again and again :-)

rawc, as I said two comments above: Artworks DO always hang around - forever! The really bad ones whose rating is going lower and lower will be auto rejected once they are below a certain rating value. This only happens when an artwork has at least at least 25 votes so that there is sufficient certainty (believability) of the rating. Please refer to http://www.thebroth.com/blog/118/bayesian-rating

The auto rejection feature has nothing to do with time as a factor.

They stay around forever, except the time it takes. The whole point here is that if a work of art is below a certain threshold in terms of quality, as determined by its rating, so it will automatically be rejected, but only if enough votes, so we have a high enough certainty that the artwork is really bad. 25 is that votes count refers to - it’s 25 votes in total, more or less.
