We are currently looking at the idea of putting the ChefMoz restaurant ratings and reviews into our database. Right now I think we have a catch 22 where people see we don’t have many reviews yet so they don’t write reviews, if there were more reviews it might snowball on itself.
ChefMoz is a free set of restaurant data and review information from the open directory project (DMOZ), while we have at little less than twice the restaurants that they do, they have lots of reviews that would really help to give us a baseline.
It looks like, from just a peek at their documentation that they rate things 1-10 instead of 1-5, but we could convert that. I think that this would actually be possible to integrate this data into our database and have the recommender algorithm work with it.
We are quite excited by the prospect of this, and it may actually be put on the fast track before our other 2 secret projects
