Comments on: A recommendation for Amazon.com’s recommendation system http://blog.cgsm.com/2010/03/02/a-recommendation-for-amazon-com%e2%80%99s-recommendation-system/ Thoughts on Marketing and Other Stuff Sat, 28 Jan 2012 02:26:57 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Thai Online Shopping http://blog.cgsm.com/2010/03/02/a-recommendation-for-amazon-com%e2%80%99s-recommendation-system/comment-page-1/#comment-948 Thai Online Shopping Wed, 21 Apr 2010 04:11:19 +0000 http://blog.cgsm.com/?p=439#comment-948 Hi, I've been doing a lot of research online lately regarding traffic and SEO since I just opened up an Thai online shop with a couple of buddies. The information offered on your site would be of great value to GetSiam visitors, and I believe, your visitors would find great value in our site. Because our two websites are complementary rather than competitive, I see synergy here as an opportunity for our mutual benefit and I'd really like to exchange links with your website. Have a look at our site if you want, we put a lot of work and effort into it and are dedicated to improve it constantly. We receive a lot of hits already (contact me for visitor stats) and I think both our sites can benefit from one another. Anyway, just thought I'd share this with you - keep up the good work and get back to me if interested! Hi,

As you note, any recommendation system is only as effective as the data it has to leverage, and I think Amazon is limited by drawing only on correlations between users. Collaborative filtering has significant disadvantages as a recommendations approach, which I think is why we're seeing more recommendations systems taking other approaches - for example, at Jinni http://www.jinni.com our recommendations have a semantic basis.
