        The model analyzes the **meeting minutes** to automatically extract **structured metadata** using a *Named Entity Recognition (NER)* approach.

        Each token in the document is classified, identifying information such as:
        - 📅 **Date**
        - 🕐 **Start / End time**
        - 📍 **Location**
        - 📋 **Minute ID**
        - 📌 **Meeting type**
        - 👔 **President** (present / absent / substituted)
        - 👥 **Councilors** (present / absent / substituted)

        The model uses the **BIO tagging scheme** (*Begin, Inside, Outside*) to mark entity boundaries, and the final spans are reconstructed from token-level predictions.
