Quality in Databases

Data quality has been a major concern of organizations for decades. The recent advances in artificial intelligence (AI) have brought data quality (DQ) back into the spotlight: while many recent data quality and cleaning solutions are powered by ML, DQ is a core requirement to ensure reliable AI-based systems. DQ is tackled from different perspectives by different research communities, including database, machine learning (ML), and information systems. We believe it is important to bring together these communities to foster a vital discussion about the future of DQ assessment and improvement.

Considering the large number of participants (>50) at QDB’23, QDB'24 aims to (1) continue to host the vital discussions about data quality, and (2)  exchange best practices and novel methods for (semi-)automated (ML-based) data quality assessment and improvement in the context of AI-based systems.

Keynote

Title: How Data Management Research Helps to Improve Real World ML Applications 

Abstract: The talk will given an overview of our past and recent research to improve data quality in ML applications, based on proven principles and techniques from data management. In particular, we will cover work on declarative data unit tests tailored for large-scale data lakes, on reasoning about the datasets for ML applications by treating ML pipelines as algebraic queries, and on leveraging fine-grained data provenance as a foundation for data debugging systems.

Sebastian Schelter is a Full Professor at the Berlin Institute on the Foundations of Learning and Data (BIFOLD) and Technische Universität Berlin. His research is focused on the intersection of data management and machine learning with the goal to foster the responsible management of data and to democratise data science technologies. The research of his group is accompanied by efficient and scalable open source implementations, many of which are applied in real world use cases, for example in the Amazon Web Services cloud and in large European e-commerce platforms. In the past, he has been an assistant professor at the University of Amsterdam, a faculty fellow at New York University, a senior applied scientist at Amazon Research and a research intern at Twitter and IBM Almaden in California. His research contributions have been recognized with an ACM SIGMOD Systems Award, an ACM SIGMOD Best Demo Runner Up Award, and a Best Paper Runner Up Award from the Table Representation Learning workshop at NeurIPS.

Manuscript Preparation

Submission
Authors are invited to submit original, unpublished full research papers and demo descriptions that are not being considered for publication in any other forum.
Please submit your paper as a PDF using Microsoft's QDB CMT site. You need to append the category tag as a suffix to the title of the paper such as “Data Management in the Year 3000 [Regular]”; “Spatial Database System [Demo]”. This must be done both in the paper file and in the CMT submission title. The suffix will not be part of the camera-ready copy if the paper is accepted.

Format
It is the authors' responsibility to ensure that their submissions adhere to the VLDB format detailed here. In particular, it is not allowed to modify the format with the objective of squeezing in more material. Submissions that do not comply with the formatting detailed here will be rejected without review. Note that the limit of up to 6 pages (including all figures, tables, and references) must be followed for both full papers and demos.

Publication
Accepted papers will be distributed via the CEUR workshop proceedings.

Past Events

We are building on an established tradition of eleven previous international VLDB workshops concerning data and information quality.
