You can do one more step and build a recommendation system that tracks not only trust but individual preferences. Performace requirements are pretty steep for real-time recommender, but it is totally worth it.
Oh, by the way, we have it implemented already on jaanix. For an opensource implementation you can take a look at http://www.advogato.org/ http://www.advogato.org/
- ntoshev 18y agoDo you have implemented the described system, a recommendation system, or both? If you have implemented similar global estimation of how much every vote counts, I'd be interested in hearing how did it actually affect your site.
- gaika 18y agoIt is both. Trust and recommendations are mixed together in an SVD like algorithm as described in http://sifter.org/~simon/journal/20061211.html http://sifter.org/~simon/journal/20061211.html . On top of that jaanix lets you adjust all your personal preferences in real-time. The biggest effect is that it is discouraging trolls and spammers, as there's no front page they can spam or troll. The downside is that the critical mass required to make the site truly social is a lot higher, and unfortunately we have not figured out how to gain enough users for it to really shine.
- ntoshev 18y agoI agree recommendations are a way to take trust into account, but it is a different way with its own drawbacks. You wouldn't need higher critical mass if you have just implemented a pagerank equivalent as opposed to recommendations. You can make a page without recommendations the default, at least until you acquire critical mass. You can just have a "personalized" slider defaulting to no personalization.
