 <p>Recommenders have changed over the years. Mahout contains a long list of them, which
you can still use. But to get the best  out of our more modern aproach we'll need to think
of the Recommender as a "model creation" component&mdash;supplied by Mahout's new spark-itemsimilarity
job, and a "serving" component&mdash;supplied by a modern scalable search engine, like
-<p><img alt="image" src="" /></p>
+<p><img alt="image" src=""
 <p>To integrate with your application you will collect user interactions storing them
in a DB and also in a from usable by Mahout. The simplest way to do this is log interactions
to csv files (user-id, item-id). The DB should be setup to contain the last n user interactions,
which will form part of the query for recommendations.</p>
 <p>Mahout's spark-itemsimilarity will create a table of (item-id, list-of-similar-items)
in csv form. Think of this as an item collection with one field containing the item-ids of
similar items. Index this with your search engine. </p>
 <p>When your application needs recommendations for a specific person, get the latest
user history of interactions from the DB and query the indicator collection with this history.
You will get back an ordered list of item-ids. These are your recommendations. You may wish
to filter out any that the user has already seen but that will depend on your use case.</p>
