A beer recommendation system made with R

This neat little app is the product of a recommendation system built using the R language by the folks behind the yhat blog. It’s based on about 1.5 million beer reviews from the Beer Advocate. The ratings were read into a Postgres database and then imported to R using the RPostgreSQL package. From there, you can easily make a start at collaborative filtering in R by using the intersect function to identify all reviewers that have rated a particular pair of beers, and write a distance function in R to measure how close the two beers are according to the reviewers’ ratings. Do this for all pairs of beers (using a neat application of the expand.grid function), put the results behind a JavaScript UI, and you’ve got yourself a beer recommender. (This is similar to the approach used for this recommendation engine for movies.)
