VinWiki Part 1: Building an intelligent Web app using Seam, Hibernate, RichFaces, Lucene and Mahout
From the webpage:
This is the first post in a four part series about a wine rating and recommendation Web application, named VinWiki, built using open source technology. The purpose of this series is to document key design and implementation decisions, which may be of interest to anyone wanting to build an intelligent Web application using Java technologies. The end result will not be a 100% functioning Web application, but will have enough functionality to prove the concepts.
I thought about Lars Marius and his expertise at beer evaluation when I saw this series. Not that Lars would need it but it looks like the sort of thing you could build to recommend things you know something about, and like. Whatever that may be. 😉
