CLASSER_Sanskrit_MuRIL

This model is a fine-tuned version of MuRIL on the Sanskrit CLASSER dataset for Fine-grained Named Entity Recognition.

The tagset of MultiCoNER2 is a fine-grained tagset. The fine to coarse level mapping of the tags are as follows:

• Location (LOC) : Facility, OtherLOC, HumanSettlement, Station
• Creative Work (CW) : VisualWork, MusicalWork, WrittenWork, ArtWork, Software
• Group (GRP) : MusicalGRP, PublicCORP, PrivateCORP, AerospaceManufacturer, SportsGRP, CarManufacturer, ORG
• Person (PER) : Scientist, Artist, Athlete, Politician, Cleric, SportsManager, OtherPER
• Product (PROD) : Clothing, Vehicle, Food, Drink, OtherPROD
• Medical (MED) : Medication/Vaccine, MedicalProcedure, AnatomicalStructure, Symptom, Disease

Model performance:

Precision: 77.62 <br> Recall: 78.99 <br> F1: 78.30 <br>

Training Parameters:

Epochs: 6 <br> Optimizer: AdamW <br> Learning Rate: 5e-5 <br> Weight Decay: 0.01 <br> Batch Size: 64 <br>

Sample Usage

The AWED-FiNER agentic tool can be used to interact with expert models trained using this framework. Below is an example:

pip install smolagents gradio_client

from tool import AWEDFiNERTool

tool = AWEDFiNERTool(
    space_id="prachuryyaIITG/AWED-FiNER"
)

result = tool.forward(
    text="Jude Bellingham joined Real Madrid in 2023.",
    language="English"
)

print(result)
