Preface Georgios Drakopoulos1 and Eleanna Kafeza2 1 Department of Informatics, Ionian University, Greece 2 College of Interdisciplinary Studies, Zayed University, UAE The CIKM 2022 workshop volume consists of the papers presented at seven of the workshops of the 31st ACM International Conference on Information and Knowledge Management (CIKM 2022). The following workshops are included in this volume (in alphabetical order):  AIMLAI: Advances in interpretable machine learning and artificial intelligence  AnalytiCup – EvalRS: A rounded evaluation of recommender systems  HIL-DC: Human-in-the-loop data curation  MICROS: The 2nd workshop on mixed-initiative conversational systems  PAS: The 1st international workshop on privacy algorithms in systems  PASIR: First workshop on proactive and agent-supported information retrieval  THECOG: The 2nd workshop on transforms in behavioral and affective computing As it can be seen from the above list, the CIKM workshops cover a wide array of interdisciplinary topics including data mining, data curation, recommendation systems, interpretable AI, privacy, IR, conversational systems, and behavioral sciences. Thus, they constitute open fora for idea exchanges and fruitful collaborations between researchers of diverse backgrounds. At this point we would like to take a moment to thank all authors, participants, and workshop organisers for their work. Without them this volume would have never been possible.
