T-Assess: An Efficient Data Quality Assessment System Tailored for Trajectory Data

Summary: T-Assess: an automated, trajectory-specific data-quality assessment system defining comprehensive criteria (validity, completeness, consistency, fairness) and supporting both offline and real-time stream evaluations. Introduces evaluation optimizations for efficiency and demonstrates superior coverage and practical effectiveness versus general-purpose DQ tools on four real-world trajectory benchmarks.
