The intersection of linguistic typology and Natural Language Processing (NLP) has given rise to a critical question: Do deep learning models, specifically transformer-based architectures like RoBERTa, learn to represent the structural diversity of human language in a way that mirrors linguistic theory? This paper explores the relationship between the World Atlas of Language Structures (WALS) and the internal representations of RoBERTa . We analyze how models organize languages into "sets" based on structural features, the methodology for probing these representations, and the implications for multilingual NLP.

The classic whale motif features a block-print aesthetic that reflects traditional artisanal Indian textile methods.
Sentences from the target languages are passed through the pre-trained RoBERTa model. The model's hidden states (usually from the final layers) are extracted.
The metric is a prominent example of a typology-based similarity metric. By converting discrete WALS feature values into a numeric scale, researchers created a continuous measure of linguistic distance. This measure was validated against linguist expert surveys and computational benchmarks, proving to be a highly effective tool for modeling language similarity.
: By knowing a language's WALS features, developers can predict how well a model trained on English might perform on a distant language like Swahili.
