More on "More Like This" Recommendations in SOLR

Big Data

Companies like Amazon, Netflix, and Youtube have popularized mantras like "More Like This" recommendations. Now, almost all online shops/content sites implement such solutions.

But is it possible to build a scalable Content-Based Recommendation System using open-source software that is easy-to-maintain, simple to tune and straightforward to deploy?

I will present how to use "More Like This" from Apache SOLR. Built as a Search Tool, Apache SOLR can also be used as a Recommendation System as they both operate with computing relevance.

However, the "More Like This" functionality of SOLR uses only text fields. I will show you how to overcome this and fully profit from the powerful capabilities of SOLR.

I will also present how an Inverted Index works, the TF/IDF scoring formula and how to measure the performance of a Recommendation System. All with a step-by-step example.

Scheduled on Thursday from 12:40 to 13:20 in Track 1
