PleIAs/KaribuAI

The Karibu project is a collaboration between pleIAs, Bibliothèque sans frontière (BSF) and Kajou. Our platform delivers comprehensive educational activities across six CEFR proficiency levels (A1 to C2), making quality language learning accessible to all, even in offline environments through microSD card deployment. By combining reading comprehension, interactive exercises, and personalized learning paths, Karibu creates an immersive educational experience that adapts to each learner's needs.

Karibu Language Level Classifier

KaribuAI is a DeBERTa-based classifier that automatically assigns CEFR language proficiency levels (A1-C2) to French educational content.

Architecture: DeBERTa with multi-head classification

• Model Size: Fine-tuned from DeBERTa-v3-small
• Output : 6 classification levels (A1, A2, B1, B2, C1, C2)

Training Details

• Training Data: 9,000 synthetic samples 🔍 Explore the full dataset

• Source: French press articles + Wikimedia content

• Processing: Sequential text simplification using an open source model (to be published)

• Validation: 1,000 samples per level manually verified by BSF experts

Cultural Relevance and Ethical Content Curation

Understanding the importance of cultural context in language learning, we've implemented a robust content filtering system that ensures all materials are not only educationally sound but also culturally sensitive.

• Topics coverage : Solidarity, geography, African literature, agriculture, tourism, cultural events, African history, geopolitics, communication
• Topic Filtering: Meta-Llama-3-8B-Instruct for content categorization
• Toxicity filtering : Celadon
