Abstract: In this report, we offer a brief overview of the contributions and takeaways from the Joint KaRS & ComplexRec Workshop, co-located with the 15th edition of the ACM RecSys in Amsterdam, The Netherlands. With this workshop, we aimed to merge the main objectives envisioned for the 3rd Edition of the Workshop of Knowledge-aware and Conversational Recommender Systems and the 5th Edition of the Workshop on Recommendation in Complex Environments. This joint workshop adopted a hybrid format aligned with the goal of this year's main conference congregating to continue to build community around recommender systems research and development. Date: 27th September-1st October, 2021. Website: https://kars-workshop.github.io/2021/program/.
