Ramon Navarro Bosch - Plone 5 and how to use machine learning with it. [EuroPython 2015] [22 July 2015] [Bilbao, Euskadi, Spain] Plone is a Document Management System and Content Management System that has been in the Python scope for more than 10 years. Plone 5’s features allow us to manage content, define various kinds of content and provide a nice useful UI to work on semantic web technologies. In this talk we are going to explain our approach for using Plone with the Python machine learning toolkit sklearn (http ://scikit-learn.org/stable/) to enable clusterization and classification of content using a scalable content management system. We will also add some sophisticated front-end gloss using the new functionalities on frontend development added on Plone 5 and some real use cases of CMS/DMS with machine learning using sklean and solr.
