[0] http://hyperdev.fr/notes/a-graph-based-movie-recommender-engine-using-guile-scheme.html This introduce traversi framework to do graph traversal. traversi is inspired from Tinkerpop's Gremlin. Traversi is a custom stream library which is faster than srfi-41 and support backtracking. I think that building traversi on top of streams make graph traversal much more approachable. This article is inspired from a *graph-based recommender engine* [1] [1] https://markorodriguez.com/2011/09/22/a-graph-based-movie-recommender-engine/ Have fun!
