Semantic Quality of AAS Submodel Templates: Dataset and LLM-Based Validation Approach

The Asset Administration Shell (AAS) enables semantic interoperability in Industry 4.0, yet the growing number of Submodel Templates (SMTs) raises concerns about their semantic quality. Due to their interdisciplinary creation, SMTs often contain inconsistencies and ambiguities, especially in open domains. However, exis...

When Data Augmentation Falls Short: Wi-Fi Fingerprint-Based Indoor Localization Revisited

Generative data augmentation has been widely explored in Wi-Fi fingerprint-based indoor localization to reduce the cost of dense radiomap construction, with many studies reporting substantial localization improvements. However, these comparisons typically rely on default or weakly optimized baseline regressors, making...
