CURED: Creating, Understanding, and Repairing Errors Demonstrator

2026-07-22

AI Summary

This work addresses the gap between theory and practice in error detection and cleaning for tabular data by proposing and implementing an interactive web-based demonstration system that integrates error modeling, injection, and intelligent cleaning. For the first time, the system unifies machine learning–based data cleaning methods with dependency-aware error generation models within a visual platform, enabling users to upload tables, inject realistic errors, and interactively experience the cleaning process alongside interpretable explanations of the underlying mechanisms. By synergizing machine learning, database technologies, and web development, the project enhances intuitive understanding of error repair principles and provides a publicly accessible demo platform (https://cured.demo.calgo-lab.de/) that serves as an effective validation tool for both research and practical applications in data cleaning.

Abstract

Detecting and cleaning errors in tabular data is a prerequisite for data intense software applications. Recent research at the intersection of Machine Learning (ML) and Database Management Systems (DBMS) highlights the potential of statistical learning algorithms for error detection and cleaning. This paper combines our recent work on ML-based data cleaning and error models in a unified demonstrator. The web application allows users to upload tabular data, perturb the data with realistic data dependent errors and use modern ML methods to clean and understand error mechanisms in data. Our demonstrator helps to bridge the gap between theoretical advancements and intuitive practical insights in the context of error models and data cleaning algorithms for tabular data. The demonstrator is available at https://cured.demo.calgo-lab.de/
