-## About NumidiaNLP
-
-**NumidiaNLP** is a research initiative focused on Natural Language Processing
-for **Maghrebi Arabic and North African social-media language**.
-
-Our work investigates computational representations of the linguistic
-variation observed across **Algeria, Morocco, and Tunisia**, including
-dialectal Arabic, non-standard orthography, Arabizi, and multilingual
-code-switching.
-
-The objective is to develop and evaluate reusable language resources that
-support rigorous and reproducible research on underrepresented Maghrebi
-language varieties.
-
----
-
-## Research Areas
-
-Our current research focuses on:
-
-- Maghrebi Arabic language modeling
-- Regional language-model adaptation
-- Hate and offensive language detection
-- Sentiment analysis
-- Arabizi and Latin-script Maghrebi Arabic
-- Arabic–French and multilingual code-switching
-- Maghrebi dialect identification
-- Corpus construction and annotation
-- Robust and reproducible NLP evaluation

-## MagharibiBERT
-
-### A Regionally Adapted Language Model for Maghrebi Arabic
-
-[**MagharibiBERT**](https://huggingface.co/NumidiaNLP/MagharibiBERT)
-is a regional language model developed to provide reusable contextual
-representations for heterogeneous Maghrebi Arabic.
-
-The model follows a continued-pretraining strategy over a large and diverse
-collection of Maghrebi text covering Algerian, Moroccan, and Tunisian
-linguistic variation.
-
-Its training data preserve important characteristics of real-world Maghrebi
-communication, including:
-
-- dialectal Arabic;
-- spelling variation;
-- Arabizi;
-- Arabic–French/English code-switching;
-- informal social-media language.
-
-The objective is not to replace country-specific models, but to investigate
-whether **regional continued pretraining can provide transferable
-representations across Maghrebi countries and NLP tasks**.
-
-➡️ **Model:** https://huggingface.co/NumidiaNLP/MagharibiBERT

-
-## Evaluation Philosophy
-
-NumidiaNLP promotes evaluation practices that go beyond reporting a single
-best score.
-
-Our experiments emphasize:
-
-- fixed train/validation/test partitions;
-- multiple random seeds;
-- Macro-F1 as a primary metric for imbalanced classification tasks;
-- validation-based model selection;
-- comparisons with regional and general Arabic language models;
-- statistical analysis where appropriate;
-- computational-cost reporting;
-- transparent reporting of limitations and negative results.
-
-We consider cross-country robustness and stability important criteria when
-evaluating regional Maghrebi language models.
-
----
-
-## Regional Perspective
-
-Maghrebi Arabic is characterized by substantial variation across countries,
-communities, writing systems, and communication contexts.
-
-For this reason, NumidiaNLP studies the Maghreb not as a single homogeneous
-dialect, but as a **linguistically diverse regional continuum**.
-
-Our research aims to understand when regional representations are beneficial,
-when country-specific models remain preferable, and how both approaches can
-complement each other.
-
----
-
-## Open and Reproducible Research
-
-Where licensing, ethical requirements, and publication policies permit,
-NumidiaNLP aims to provide:
-
-- pretrained models;
-- evaluation code;
-- benchmark configurations;
-- dataset documentation;
-- reproducible experimental protocols.
-
-Research artifacts are released with appropriate documentation describing
-their intended use and limitations.

+## About
+
+**NumidiaNLP** is a research initiative dedicated to Natural Language
+Processing for **Maghrebi Arabic and North African digital language**.
+
+Our research focuses on the linguistic diversity observed across
+**Algeria, Morocco, and Tunisia**, including dialectal Arabic,
+non-standard orthography, **Arabizi**, and multilingual
+**code-switching**.
+
+The broader objective is to develop reusable language models, datasets,
+and evaluation resources for underrepresented Maghrebi language varieties.

+## 🌍 MagharibiBERT
+
+### A Regionally Adapted Language Model for Maghrebi Arabic
+
+**MagharibiBERT** is a regional language model developed to provide
+reusable contextual representations for heterogeneous Maghrebi Arabic.
+
+It is adapted through large-scale continued pretraining over diverse
+Maghrebi text representing linguistic variation from Algeria, Morocco,
+and Tunisia.
+
+The training resources preserve important characteristics of real-world
+Maghrebi communication, including dialectal variation, non-standard
+orthography, Arabizi, and multilingual code-switching.
+
+The central research question is:
+
+> **Can regional continued pretraining provide transferable language
+> representations across Maghrebi countries and NLP tasks?**
+
+🤗 **Model:**  
+https://huggingface.co/NumidiaNLP/MagharibiBERT
+
+---
+
+## Regional Perspective
+
+Maghrebi Arabic is not treated as a single homogeneous dialect.
+
+Instead, we consider it a **linguistically diverse regional continuum**
+with substantial variation across countries, communities, scripts,
+platforms, and communication contexts.
+
+Our research therefore investigates both:
+
+- the value of **shared regional representations**, and
+- the complementary strengths of **country-specific models**.
+
+---
+
+## Evaluation Principles
+
+Our experimental methodology emphasizes:
+
+- fixed train/validation/test partitions;
+- multiple random seeds;
+- validation-based checkpoint selection;
+- Macro-F1 for imbalanced classification tasks;
+- comparisons with general Arabic and regional language models;
+- statistical analysis where appropriate;
+- reporting of computational requirements;
+- transparent reporting of limitations and negative results.
+
+The objective is not merely to obtain the highest score on one dataset,
+but to study **cross-country robustness, stability, and transferability**.
