MASEU Multilingual

Dataset Description

MASEU is a dataset specifically constructed to enable reliable and linguistically faithful evaluation of mathematical reasoning in Basque, a low-resource language. It is based on a manually curated subset of the mawps-asdiv-a_svamp corpus, which merges three well-established benchmarks in the domain of Math Word Problems (MWPs): MAWPS, ASDiv-A, and SVAMP. These datasets were selected for their diversity in reasoning types, consistent structure, and pedagogical value, making them particularly suitable for testing LLM performance in multilingual and instructional contexts.

The Basque portion of MASEU comprises 195 train entries and 1584 test entries, all carefully translated into Basque by a single native speaker, without the use of any machine translation tools or automated assistance. The translation process was fully manual and carefully controlled to ensure both mathematical fidelity and linguistic naturalness, faithfully preserving the original intent, difficulty level, and logical structure of each problem. This guarantees that the Basque version reflects idiomatic usage while maintaining conceptual equivalence, enabling robust reasoning evaluation without introducing semantic drift.
