Categoriesvary denotes the phenomenon in data science and information science where category labels, taxonomies, or class definitions differ across datasets, systems, or contexts.

Formalization: There is no single universal metric for categoriesvary; it is commonly assessed using measures such
Examples: A product catalog uses “electronics,” “gadgets,” and “devices” as categories in one system, while another
Implications: High levels of categoriesvary can impede data integration, model generalization, and cross-domain analysis. Addressing it
