| Hi, everyone. I need to get more educated about collaborative filtering and how to efficiently implement it in SQL server, using analysis services and or homegrown t-sql.Can someone recommend a book? Are there any that are good for both explaining the basics, theory, and math, as well as implementation on SQL server?Thanks-b |

| Well, I didn't know what this was so I googled and wikipediad it to find out. Unfortunately, i don't have any first hand experience with CF, but i thought I'd pass on the links I found.Since I didn't even know what collaborative filtering was (had an idea, turns out I was dead on). Anyway, wikipedia pointed me to this site with many links to research papers and such on the subject. unfortunately I didn't see anything detailing a SQL implementation.http://pespmc1.vub.ac.be/COLLFILT.htmlalso check the wikipedia artcle here http://en.wikipedia.org/wiki/Collaborative_filtering and click the links to the non-commercial implementations of collaborative filtering. These sites then link you to more info on algorithms used and their implementation. Interesting stuff.-ec |

| Thanks for the links!I've got some hacked together implementations of collaborative filtering going, and they are working well in my application.What I'm looking for is more of a SQL-server centric education. For instance, I believe the the decision trees OLAP algorithm can be used for CF; what I don't know is the relative merits of doing so versus a t-sql based implementation. And, I expect that there are CF specific issues with regards to indexing and query design.Thanks again for the links; they'll definitely help in my hacking, but I'd love to hear if anyone knows a more formal reference for CF on SQL Server (I looked at amazon and stuff before posting, with no luck).Cheers-b |
