numind/NuNER-v1.0

SOTA Entity Recognition English Foundation Model by NuMind 🔥

This model provides the best embedding for the Entity Recognition task in English.

We suggest using newer version of this model: NuNER v2.0

This is the model from our Paper: NuNER: Entity Recognition Encoder Pre-training via LLM-Annotated Data

We suggest using newer version of this model: NuNER v2.0

Here is the aggregated performance of the models over several datasets.

k=X means that as training data for this evaluation, we took only X examples for each class, trained the model, and evaluated it on the full test set.

Model	k=1	k=4	k=16	k=64
RoBERTa-base	24.5	44.7	58.1	65.4
RoBERTa-base + NER-BERT pre-training	32.3	50.9	61.9	67.6
NuNER v0.1	34.3	54.6	64.0	68.7
NuNER v1.0	39.4	59.6	67.8	71.5
NuNER v2.0	43.6	61.0	68.2	72.0

NuNER v1.0 has similar performance to 7B LLMs (70 times bigger than NuNER v1.0) created specifically for the NER task.

Model	k=8~16	k=64~128
UniversalNER (7B)	57.89 ± 4.34	71.02 ± 1.53
NuNER v1.0 (100M)	58.75 ± 0.93	70.30 ± 0.35

Usage

Embeddings can be used out of the box or fine-tuned on specific datasets.

Get embeddings:

import torch
import transformers


model = transformers.AutoModel.from_pretrained(
    'numind/NuNER-v1.0'
)
tokenizer = transformers.AutoTokenizer.from_pretrained(
    'numind/NuNER-v1.0'
)

text = [
    "NuMind is an AI company based in Paris and USA.",
    "See other models from us on https://huggingface.co/numind"
]
encoded_input = tokenizer(
    text,
    return_tensors='pt',
    padding=True,
    truncation=True
)
output = model(**encoded_input)

emb = output.last_hidden_state
