There is a request for a comment on this issue Controversial posts and comments #2515. Do you have any ideas on how best to implement this?
I’d like to see some more people chime in with opinions, but maybe that’ll come with a PR. At the very least, it’s something that can be moved forward with.
My first thought is to rank items by
totalVotes / score. This would prioritize posts that get lots of votes in both directions.Example:
def getControversialScore(upvotes, downvotes): return (upvotes + downvotes) / abs(upvotes - downvotes) getControversialScore(50, 10) # 1.5 getControversialScore(4, 5) # 9 getControversialScore(6, 30) # 1.44 getControversialScore(30, 28) # 29It might depend on the definition but I’d probably expect engagement/total to play a bigger factor.
As it is it weights very heavily towards evenness:
A:(11, 10)=21
B:(99, 90)=21They have the same ratio of votes but I’d expect
Bto be more controversial since more votes are tied up in the controversy / it got more attention. Maybe most people just don’t care aboutAso they didn’t bother to vote.If you square the numerator then the busier comments would score higher.
I like this. Super clean and simple.
That said, I suspect Reddit’s ‘controversial’ sorting might work a little differently, as I often used it to see what the crazy people were saying.
I haven’t played with the numbers, but I’m not sure that your proposal would push the crazies to the top - just the moderate crazies.
If I was God Emperor for any sort of content algorithm, I’d want to try a decentralized “simulated annealing” of feature vectors based on up/down votes, subscriptions, etc. That lets you create linear combinations (eg on Wikipedia the vector for King - Man might be close to Royalty) and share them around on different platforms. This makes The AlgorithmTM a lot more transparent and user-driven, since you can feasibly program on a per-user basis all sorts of policies for how their own preference vector updates, or they could have layers of linearly combined vectors for base style, mood, binging, etc.
What I like about this is it doesn’t presume some kind of inherent value - it implies a philosophy that everything is equally valid/valuable to someone, and people just have different preferences for what they prefer. If it’s something utterly vile that everyone downvotes into oblivion, that’ll naturally sink into the recesses of feature-space that occupy the opposite of whatever “all humans” value.
I think this is brilliant but not what they’re looking for. You should absolutely spread this idea around if you’re not willing to get a group together to implement it.
In my dreams I’d also like to see separate drop downs for timespan and criteria. They could even have options referring to different time dropoff curves. Then the traditional past day, past week, etc would effectively be flat.
