Elo/Trueskill sounds like a solid idea.
When you go to rate a book the system asks you if it was better or worse (maybe same) then a book of you previously read closest in rating or some hidden matchmaking rating (MMR).
I think having books having both a personal and global score would be nice as well.
I don't think it would be possible for someone to change their rating but that may be a feature.
I also don't think this solves recommendation though it may be useful as a feature.
- MrVandemar 3y ago> I don't think it would be possible for someone to change their rating but that may be a feature. It should definitely be possible. Take films. I had a friend who would go see a film. On the day he saw it: "OMG THE BEST THING EVER". Next Week: "Yeah, that was a good film". A month later: "Yeah it was okay I guess". Six months later: "A bit ordinary really" In 1990 if you'd asked me to rank the Alien films, I would have put ALIENS first, and ALIEN second. These days, I reverse those rankings. People's tastes change over time. It would be inaccurate to "fix" a rating in stone.
- helges 3y agoYeah, I think what was meant is that the Elo rating system might make it difficult to account for changes in the rating. People change their minds all the time (and it's a good thing), I agree.
- aleksiy123 3y agoYes, this is what I meant. Changing the rating would require storing every rating and recalculating all dependent ratings which could be quite a large DAG. While not impossible I don't think it would be particularly scalable.
