Show HN: Movie Recommendations for several people to watch together(foundd.com)

We've been working on a custom engineered collaborative filtering algorithm not only to recommend movies for one person but for several to watch together, at the same time.

We're still in closed beta but would love to get feedback before launching.

The site is written in Java, using Tapestry 5 & jQuery. Persistence via MongoDB.

We're still in closed beta but would love to get feedback before launching.

Nice site, cool idea. Though I found that most of the movies just seemed to be the popular ones... and many that I'd already watched. I'm guessing it matches with your Facebook likes?

We structured the recommendations to be 100% personalized, so it might be that you have more a popular taste? If not please let me know as it should really recommend long tail content too. Could also be that our rated item set is still not very large. We just use FB Likes to let you rate those (to increase relevance for items we ask you to rate) but don't use FB Likes in the recommendations. Yeah def. gonna be some movies in your watchlist that you've seen already, we hope it creates trust in the recommendations and we made rating super fast - one person rated 1,600 movies in 90 mins :)

Looks great so far! A question, though: why are the group sizes limited to 5 people? Is it an issue with the cross referencing being too strict to find good matches with more people? I would like to have a larger group size, 10 would be ideal, though even just 7 would be a big help.

Thanks for the feedback. The rated item base for now is not yet large enough to give good recommendations to a large group of people. We'll be able to extend group size in the future.

Looks cool.

Minor comment though, when I saw the cell phones, the first thing I thought of was button candy. http://2.bp.blogspot.com/_ooCR1rvj6h4/TSFPFXg1CFI/AAAAAAAAB_...

Supposed to be remote controls...

Love the idea, but my first thought was "man, I have to rate everything I've watched/read/played AGAIN???" I really wish there was better interchange/exchange of this sort of data, because it's sad that my first impression of your app is so quickly soured by that.

lassecausen 14 years ago | |

Yeah that's a good point. We're gonna work on that, for now we just wanted to test the group recommendations...

Excellent!

watchlist recommendations were dead on! i might totally use this. one thought though: if i could, i'd share my list of ratings on facebook or elsewhere - and i'd totally want check out rating-lists by others. for all those who won't invite friends to a group (for now i won't), such a feature could be in my interest and provide a low threshold mechanism to spread the word about foundd at the same time.

yeah that's a good idea

I think this is great. It'd be nice if google account login was available though.

lassecausen 14 years ago | |

Thanks, glad you're liking it. Gonna work on google login soon...
