srl_bert_model

This repository contains a BERT-based model for Semantic Role Labeling (SRL).

Model Description

We revisit structured SRL modeling with a modernized encoder-based framework that preserves explicit predicate-argument structure while enabling 10× faster inference than AllenNLP.

• Model name: srl_bert_model
• Repository: yeomtong/srl_bert_model
• Architecture: BERT-based SRL model
• Framework: PyTorch
• Task: Semantic Role Labeling

Intended Use

This model is intended for:

• semantic role labeling research
• predicate-argument structure analysis
• downstream NLP tasks that require structured semantic information
• experimentation with role-aware language representations

How to Use

Example loading code should be adapted to your project setup.

from huggingface_hub import hf_hub_download, snapshot_download

ckpt_path = hf_hub_download(
    repo_id="yeomtong/srl_bert_model",
    filename="best_srl_Sep_29.ckpt")
repo_dir = snapshot_download("yeomtong/srl_bert_model")
sys.path.append(repo_dir)

from predictor import srl_init
from model import PredicateAwareSRL
from visualizer import prediction, prediction_formatted

#load model
srl_init(ckpt_path, bert_name= "bert-base-cased")

test_sentence = "I want to go home"
prediction(test_sentence)
