[CFP - DEADLINE EXTENDED] DiversityOne Open Challenge at Ubicomp 2025: Exploring People’s Everyday Life Behavior with Mobile Data
Andrea Bontempelli
DiversityOne Open Challenge: Exploring Diversity in People’s Everyday Life Behavior with Mobile Data
held at
The ACM International Joint Conference on Pervasive and Ubiquitous Computing (UbiComp)
Espoo, Finland, October 12-16, 2025
Workshop website: https://datascientiafoundation.github.io/diversityone-2025/
The open challenge aims to explore the DiversityOne dataset, one of the larger and most geographically diverse datasets for everyday life behavior modeling. The dataset combines questionnaires about demographic and psychosocial variables from 18K participants, and passive smartphone sensor data and self-reported annotations from 782 students across eight universities in eight countries. The study followed ethical approval procedures in each of the participating institutions and is compliant with the European General Data Protection Regulation (GDPR). This dataset is a rich, flexible and valuable research resource that can be used to answer research questions in multiple fields: machine learning, mobile sensing, computational social science, behavioral recognition, and many others. This challenge offers the opportunity to work on the dataset and gain useful feedback on your research. We welcome contributions from researchers from diverse backgrounds and geographical provenances. In particular, we welcome contributions that address aspects including, but not limited to:
AI/ubiquitous computing/mobile sensing
data-centric AI
interactive machine learning
noisy annotation detection and correction
domain adaptation
transfer learning
activity and mood recognition
responsible and ethical AI
Computational social science
network analysis of social systems
sequence analysis of diary data
analysis of communities of practices
machine learning or rule-based analysis of social behavior
Designing with data
studies focusing on the design and documentation of the dataset collection
studies focusing on the design affordances of the dataset
data-centric design
user-centered design
Explore a rich, large-scale dataset for research
Receive feedback for your work from an expert program committee
