Building a relevance platform with Couchbase and Elasticsearch

These slides were from my Goto Amsterdam presentation. During this presentation I went into detail about how we're building a high performance relevance platform at Hippo with Couchbase and Elasticsearch. The talk will also cover why we chose CouchBase for storage and how Elasticsearch can be used for search and analytics. I shared how we integrated and leverage both products full-circle from within our Hippo CMS product.

8. follow the Hippo trail OneHippo @ Goto Registration Visitor - entity making HTTP requests Collector - records data about a visitor or his behavior Example: location collector (GeoIPCollector) Targeting Data - all data about a specific visitor Example: IP address is located in Amsterdam
9. follow the Hippo trail OneHippo @ Goto Matching Characteristic - a type of fact about visitors Example: "comes from a city", "experiences a type of weather" Target Group - the specification of a Characteristic Example: "comes from a European city", "comes from Amsterdam" Persona - one or more target groups that describe a certain type of visitor Example: "Jim, the European urban consumer", "Alice, the Pet owner"
