This model is a fine-tuned version of EMBEDDIA/est-roberta on a custom dataset for extracting quantifier constructions (e.g., "kari koeri", "hunnik raamatuid") in Estonian text.

It performs token classification using the BIO labeling scheme with the following labels:

O: Outside
B-QUANT: Beginning of a quantifier expression
I-QUANT: Inside a quantifier expression

🔍 Example Usage

python

from transformers import AutoTokenizer, AutoModelForTokenClassification
import torch

model = AutoModelForTokenClassification.from_pretrained("ahtokiil/est-roberta-quant-extraction_EKI")
tokenizer = AutoTokenizer.from_pretrained("ahtokiil/est-roberta-quant-extraction_EKI")

sentence = "Arsti juures tuli tükk aega oodata."
inputs = tokenizer(sentence, return_tensors="pt")
outputs = model(**inputs)
predictions = torch.argmax(outputs.logits, dim=2)

tokens = tokenizer.convert_ids_to_tokens(inputs["input_ids"][0])
labels = [model.config.id2label[p.item()] for p in predictions[0]]

print(list(zip(tokens, labels)))
