Implementation Guidelines for Data Quality Metrics

Read the original on arXiv Machine Learning →

The paper addresses the disconnect between textual data quality (DQ) dimensions and practical DQ tools by making ISO/IEC 25024 and ISO/IEC 5259 metrics executable. It classifies metrics into generalizable, parameterized, and non-generalizable categories, and provides implementation guidelines for the first two. The authors implement these guidelines in the open-source library dqmeasure, demonstrating that the metrics respond predictably to injected errors, correlate with downstream machine learning performance, and scale linearly with dataset size.

Data Quality Rule Generation with LLMs

The paper introduces LeDQeR, an approach that uses large language models to automatically generate data quality rules for rule‑based enterprise tools. It follows a generate‑filter framework where the LLM proposes candidate rules from dirty data, and four filters ensure the rules are executable, correct, generalizable, and non‑redundant. Experiments show that LeDQeR produces effective, compact rule sets across diverse datasets and error types.

Litmus: Zero-Label, Code-Driven Metric Specification for Evaluating AI Systems

Litmus is a zero-label system that automatically designs evaluation and monitoring metrics for AI pipelines by extracting evaluation intent from source code and targeted interrogation. It identifies what must be measured and why, then generates a justified, per-stage metric portfolio. In experiments on three real code-defined pipelines, Litmus outperforms AutoMetrics and DynamicRubric baselines in concern coverage, stage span, redundancy, and validity against per-row quality labels, especially on scientific QA.

Benchmarking Code LLM-as-a-Judge via Constrained Perturbation and Calibration

The paper introduces AXIOM, a perturbation-based framework for creating a balanced benchmark of code evaluation problems. AXIOM refines program quality by applying controlled semantic perturbations and then calibrates scores through selective manual annotation, resulting in the multilingual AXIOMBENCH dataset with 1,962 problems. This approach addresses limitations of prior benchmarks that rely on coarse binary labels or subjective human scoring.
