ITM-Rec: An Open Data Set for Educational Recommender Systems

With the development of recommender systems (RS), several promising systemshave emerged, such as context-aware RS, multi-criteria RS, and group RS. However, theeducation domain may not benefit from these developments due to missing information, suchas contexts and multiple criteria, in educational data sets. In this paper, we announce andrelease an open data set for educational recommender systems. This data set includes notonly traditional rating entries, but also enriched information, e.g., contexts, user preferencesin multiple criteria, group compositions and preferences, etc. It provides a testbed and enablesmore opportunities to develop and examine various educational recommender systems.
