ABSTRACT
=========

Adaptive and personalized systems have become pervasive technologies that are gradually playing an increasingly important role in our daily lives. Indeed, we are now used to interacting every day with algorithms that help us in several scenarios, ranging from services that suggest us music to be listened to or movies to be watched, to personal assistants able to proactively support us in complex decision-making tasks.

As the importance of such technologies in our everyday lives grows, it is fundamental that the internal mechanisms that guide these algorithms are as clear as possible. It is not by chance that the recent General Data Protection Regulation (GDPR) emphasized the users' right to explanation when people face intelligence systems. Unfortunately, the current research tends to go in the opposite direction, since most of the approaches try to maximize the effectiveness of the personalization strategy (e.g., recommendation accuracy) at the expense of the explainability and the transparency of the model.

The main research questions which arise from this scenario is simple and straightforward: how can we deal with such a dichotomy between the need for effective adaptive systems and the right to transparency and interpretability?

Several research lines are triggered by this question: building scrutable user models and transparent algorithms, analyzing the impact of opaque algorithms on final users, studying the role of explanation strategies, and investigating how to provide users with more control in the personalization and adaptation problems.

The workshop aims to provide a forum for discussing such problems, challenges, and innovative research approaches in the area, by investigating the role of transparency and explainability in the recent methodologies for building user models or for developing personalized and adaptive systems.

============
SUBMISSIONS
============
We encourage the submission of contributions investigating novel methodologies to exploit heterogeneous personal data and approaches to build transparent and scrutable user models. In particular, we accept three kinds of submissions:

(A) Regular papers (max. 10 pages + references - single-column ACM format)
(B) Ongoing projects, Demo and Short papers (max. 5 pages + references - single-column ACM format);
(C) Journal papers (already published - 2 pages including abstract, highlights, and a pointer to the complete paper - single-column ACM format);

Submission site: https://easychair.org/conferences/?conf=umap23 <https://easychair.org/conferences/?conf=umap23>
During the submission process select “5th Workshop on Explainable User Models and Personalized Systems (ExUM)”

All submitted papers will be evaluated by at least two members of the program committee, based on originality, significance, relevance, and technical quality. Note that the references do not count toward page limits. Submissions should be single-blinded, i.e. authors’ names should be included in the submissions. Papers must be formatted according to the new workflow for ACM publications.

All accepted papers will be published by ACM as a joint volume of Extended UMAP 2023 Proceedings and will be available via the ACM Digital Library. At least one author of each accepted paper must register for the particular workshop and present the paper there.
