FiNERVINER: Fine-grained Named Entity Recognition for Vulnerable languages of India's North Eastern Region

FiNERVINER is a high-quality fine-grained named entity recognition dataset created through annotation projection method.

The vulnerable languages are: Bodo (brx), Mizo (lus), and Manipuri (mni).

Please read the paper in LREC'26 proceedings

FiNERVINER is a part of the AWED-FiNER ecosystem: Paper | GitHub | Interactive Demo

Sample Usage

You can use the AWED-FiNER agentic tool to interact with expert models trained using this framework. Below is an example using the smolagents library:

from smolagents import CodeAgent, HfApiModel
from tool import AWEDFiNERTool

# Initialize the expert tool
ner_tool = AWEDFiNERTool()

# Initialize the agent (using a model of your choice)
agent = CodeAgent(tools=[ner_tool], model=HfApiModel())

# The agent will automatically use AWED-FiNER for specialized NER
# Case: Processing a vulnerable language (Bodo)
agent.run("Recognize the named entities in this Bodo sentence: 'बिथाङा दिल्लियाव थाङो।'")
