Important Dates

• Paper Submission Deadline: April 20, 2025
• Notification of Acceptance: May 10, 2025
• Camera-Ready Papers Due: May 28, 2025
• Workshop Date: June 10, 2025

Workshop Scope

The pervasiveness of complex AI and data analytics technologies has created new challenges for distributed data systems. These systems must manage diverse and high-velocity data sources, ranging from multivariate, audiovisual, relational, and unstructured data. Additionally, real-time streaming data requires novel computational approaches to handle its evolving nature efficiently. The RELAX 2025 workshop focuses on developing scalable and efficient data-intensive software systems that can navigate the trade-offs between strict correctness guarantees and system performance.

Topics of Interest

We invite original research papers, position papers, and works-in-progress on topics including, but not limited to:

• Trade-offs between precision and computational efficiency
• Federated learning and distributed AI for data analytics
• Robust and resilient AI-driven data pipelines
• Scalable event-based and distributed computing systems
• Data quality in analytics pipelines, including handling missing or noisy data
• Data validation techniques and quality-aware analytics in streaming environments
• Bias detection, mitigation, and fairness in AI-driven data processing
• Ethical considerations in approximate computing, including fairness in data quality, bias detection and mitigation, and ensuring reliability in approximate data processing
• Real-time analytics over high-velocity data streams
• Sustainable AI and energy-efficient data analytics

Submission Guidelines

Regular Papers – Up to 6 pages (including references)

Short Papers – Up to 4 pages (for preliminary or position papers)

Manuscripts must follow the ACM conference template. Submissions should be formatted in the ACM proceedings style (double column “sigconf” from https://www.acm.org/publications/proceedings-template , font size set to 10 pt) and submitted as PDF file via EasyChair at https://easychair.org/conferences?conf=relax2025. RELAX 2025 adopts a single-blind review process for both categories of papers. All submissions will be peer-reviewed and accepted papers will be published. Authors of selected papers may be invited to submit extended versions of their work to the special issue for Elsevier's Information Systems on "Advances in Distributed Data Processing and Event-Based Systems". RELAX 2025 plans to be an in-person event, and the authors of accepted papers are expected to arrange for in-person attendance to present the paper and answer questions.

Workshop Structure

The half-day workshop consists of three segments:

Keynote Talk –  Keynote speaker: Georgia Koutrika (Athena Research Center, Greece): Website

Paper Presentations – Accepted papers will be presented with Q&A discussions.

Panel Discussion – Experts will discuss challenges in implementing relaxed semantics in real-world applications.
