UMAP 2020 Demo and Late-Breaking Results Chairs' Preface

It is our great pleasure to welcome you to the UMAP 2020 LBR and Demo Track, in conjunction with the 28th Conference on User Modelling, Adaptation and Personalization, held online from July 12 to 18, 2020. This track encompasses two categories: (i) Demos, which showcase research prototypes and commercially available products of UMAP-based systems, (ii) Late-breaking Results (LBR), which contain original and unpublished accounts of innovative research ideas, preliminary results, industry showcases, and system prototypes, addressing both the theory and practice of UMAP. The submissions spanned a wide scope of topics, ranging from novel techniques for user and group modeling, to adaptation and personalization implementations across different application scenarios. We received 25 LBR and 4 Demo submissions. Each submission was carefully reviewed by at least 3 members of the Demo and LBR program committee, which consisted of 55 members. Out of this total of 29 submissions, 17 LBR and 2 Demos were deemed of good quality by the reviewers, and were consequently accepted (65% overall acceptance rate). They were presented in the UMAP poster and demo sessions, which collectively showcased the wide spectrum of novel ideas and latest results in user modelling, adaptation and personalization. We would like to thank the members of the Program Committee for their reviews and discussions. We truly express our gratitude to the committee, for helping us in selecting a set of good quality contributions.
