 # BL2MP (Basque L2 student-based Minimal Pairs)
 
-BL2MP (Basque L2 student-based Minimal Pairs) test set to evaluate LMs (0 shot) on grammatical knowledge of Basque.
+The BL2MP test set, designed to assess the grammatical knowledge of language Models in the Basque language, inspired by the BLIMP benchmark. The BL2MP dataset includes examples sourced from the [bai&by](https://www.baiby.com/en/) language academy,
+derived from essays written by students enrolled at the academy. These instances provide a wealth of authentic and natural grammatical errors, representing genuine mistakes made by learners and
+thus offering a realistic reflection of real-world language errors.
+
+We randomly selected 1,800 sentences from student essays provided by the bai&by academy, adhering consistently to the ”minimal pairs” criterion. To ensure a balanced diversity, we ensured an
+equal distribution of examples across three proficiency levels4 (A: Beginner, B: Intermediate, and C: Advanced) and three error types (E1: Declension, E2: Verb, E3: Structure and Order) , as shown in
+Table 1. This approach aimed to represent a vari ety of proficiency levels and error types within the dataset.
