Hybrid recommendation approach based on a voting system: Experimentation in an educational context

Abstract

We present in this paper the results of a second experiment that was recently conducted to evaluate a hybrid recommendation approach in an online learning environment. The approach consists of mixing the two approaches of content-based filtering and collaborative filtering to improve the relevance of the educational resources recommended to learners. A first experiment was carried out in 2019 and gave convincing results, which led us to repeat a second experimentation in order to confirm the results, on the one hand, and on the other hand, to modify the way learners evaluate the resources by transforming the "like" by a vote from one to five, in order to verify whether this will bring an improvement in the recommendations. This second experiment was also an opportunity to integrate an engine that guides learners' searches by adding criteria relating to their preferences and to check their satisfaction with the use of this engine. The results were globally positive.
