Source code of several services that we developed has just been released as open source code with the Apache 2.0 license. These services include:

• the Enriched EPG service: provides enriched EPG metadata data from BBC /programmes by using Lupedia to enrich program titles and people’s names.
• the Linked Data Pattern-based Recommender: uses Linked Data as background knowledge to recommend programs. The Beancounter provides user profiles (derived from the Social Web accounts of a user). Background knowledge in DBpedia, Freebase and LinkedMDB are used to find potentially interesting commonalities between items and user interests. Two example of Pattern-based recommendations (generated real-time) are this and that.

The services are written in Prolog on top of the ClioPatria framework. ClioPatria is a RDF-store and Web server implemented in SWI-Prolog.
The source code is available on github: https://github.com/schopman/NoTube-ClioPatria-services
