**** PLEASE, EXCUSE MULTIPLE POSTINGS **** Call for Papers: UMAP4Good 2026First International Workshop on User Modeling, Personalization, and Adaptive Systems for Sustainability and Social Good We invite submissions to the First International Workshop on User Modeling, Personalization, and Adaptive Systems for Sustainability and Social Good (UMAP4Good 2026), held in conjunction with the ACM UMAP 2026 conference. UMAP4Good 2026 is an in-person event. Details & submission guidelines can be found here: http://umap4good.github.io/umap4good26/ Important dates: April 14, 2026 - Paper Submission (EXTENDED) April 28, 2026 - Notification May 7, 2026 - Papers Camera-ready Submission In an era where personalization technologies increasingly shape human decision-making, integrating sustainability and social good into user-adaptive systems has become an essential challenge. Adaptive systems influence choices across many contexts, including health, mobility, education, and media consumption, positioning them as key technologies for supporting the UN Sustainable Development Goals. UMAP4Good 2026 provides an interdisciplinary venue to explore how personalization can support sustainable behaviors, ethical decision-making, and positive societal impact. We welcome works at various stages of development, including applied systems, empirical results, or theoretically grounded positions. We invite submissions in the form of full papers, reproducibility papers, short papers, and extended abstracts. Note: Accepted papers (full, reproducibility, and short) will be published in the proceedings (CEUR). Extended abstracts are editorially reviewed for workshop presentation only and will not be included in the proceedings. Topics of Interest We welcome submissions focused on sustainability perspectives, including but not limited to: - User Modeling and Adaptation for Sustainability - Modeling users’ sustainable preferences and behavior change patterns. - Personalized nudging and persuasive systems designed for sustainability. - Context-aware sustainability recommendations. - Energy-efficient modeling and "Green AI" for personalization. - Responsible and Sustainable Adaptive Systems - Multi-stakeholder adaptive systems. - Fairness, inclusion, and long-term impact modeling. - Explainability and trustworthy personalized systems. - Privacy, safety, and ethical considerations. - Evaluation and Methodology - Metrics beyond accuracy, specifically focusing on long-term, societal, and environmental impact. - Simulation-based evaluation for behavior change. - Reproducible pipelines and sustainability-aware benchmarks. - Application Domains - Education and digital well-being. - Health and lifestyle. - Media, misinformation, and social platforms. - Smart environments, mobility, and tourism. - Agriculture, energy, and resource management.
