ContextGraph

Mozilla project: “Context Graph” is a recommender system (Personalization) for the Web. The goal for Context Graph features is to help people find new stuff based on their current context https://wiki.mozilla.org/Context_Graph

disrupt how discovery is done on the web by setting up a parallel graph to the traditional map of the web that isn't based on direct linking and page-content analysis, but instead on how users in the past have interacted with the web and where they found success.
