Summary

A study by Alice Suozzi, Luca Capone, Gianluca Lebani, and Alessandro Lenci, presented at *SEM 2026, investigates the semantic competence of Italian BabyLMs, particularly their sensitivity to semantic violations. The research adapts a minimal pair benchmark to assess BAMBI, a family of small-scale language models trained on progressively larger and more complex datasets. Performance metrics, including accuracy, mean log-likelihood offset, and expected calibration error, were used for evaluation. The study further compares BAMBI's results against three larger Italian LMs. Key findings reveal insights into the development of semantic competence in small-scale models and how data scale and training strategies influence this capability, especially for low-resource languages like Italian.

Key takeaway

For NLP Engineers developing or evaluating small-scale language models for low-resource languages like Italian, this research highlights the importance of targeted semantic evaluation. You should adapt minimal pair benchmarks to precisely measure semantic competence and sensitivity to violations. Your training data scale and strategy directly influence these models' semantic abilities, suggesting that careful optimization can yield more semantically robust small LMs.

Key insights

Semantic competence in small Italian LMs can be evaluated using semantic violation benchmarks, revealing data scale and training strategy impacts.

Principles

Method

Adapt a minimal pair benchmark to assess semantic violation sensitivity. Evaluate small-scale BAMBI models trained on varied datasets. Compare performance using accuracy, mean log-likelihood offset, and expected calibration error against larger LMs.
