🏔️ Tarifit Morphological Verb Dataset (TMVD)

📌 Overview

The Tarifit Morphological Verb Dataset (TMVD) is a high-quality, human-curated resource designed to bridge the gap in Digital Language Support for Tarifit (Riffian Berber). Despite being spoken by millions in the Rif region and the diaspora, Tarifit remains a severely underrepresented Afro-Asiatic language in the NLP landscape.

Unlike many large-scale datasets for low-resource languages that rely on noisy web-scraping or inaccurate machine translation, this dataset has been manually authored and validated by a native speaker with a professional background in linguistics and multilingual proficiency (Berber, Arabic, Catalan, Spanish, French, English).

🧪 Research Value

This dataset provides a granular look at Tarifit verbal morphology, characterized by complex initial and internal changes. It is particularly valuable for:

• Instruction Tuning: Training LLMs to understand and generate grammatically correct Tarifit.
• Morphological Analysis: Evaluating the ability of models like Gemini, Llama, or Claude to handle non-concatenative morphology.
• Low-Resource Benchmarking: Serving as a "Gold Standard" for zero-shot or few-shot translation tasks involving Catalan and Spanish.

📊 Dataset Structure

The dataset contains structured conjugations for core verbs (including iri, aqqa, ttuga, gar, day), covering various tenses and moods:

• Preterite & Imperfective: Capturing the aspectual nuances of the Berber verb system.
• Future & Imperative: Including prohibitive and intensive forms.
• Deictic & Existential Verbs: Essential for building dialogue systems and spatial reasoning.
