scibert_scivocab_uncased_scicite_finetuned

SciBERT Fine-tuned for SciCite Intent Classification

This model is a fine-tuned version of allenai/scibert_scivocab_uncased on the SciCite dataset.

Model Description

Base Model: AllenAI's SciBERT pre-trained on scientific text with a domain-specific vocabulary.

Task: Citation Intent Classification — predicting why an author is citing another work (background, method, or result).

Labels:

• background (0): Citations providing prior work context
• method (1): Citations of techniques or methodologies
• result (2): Citations comparing or contrasting experimental results

Results

Achieved on the SciCite test set:

Per-class performance:

Intended Uses & Limitations

Intended Use: Automatically classify citation intents in academic papers to improve literature mining, knowledge graph construction, and semantic search applications.

Limitations: Model trained on arXiv scientific abstracts; may not generalize to other domains (biomedical, legal, etc.). Best performance on background/method classes; result class has lower precision due to class imbalance.

Training and Evaluation Data

Dataset: SciCite — 8,243 training examples, 916 validation, 1,861 test (citation contexts from arXiv papers).

Format: Citation sentence + class label. Max length: 256 tokens. Split: 80% train, 10% val, 10% test.

How to Use

Installation

pip install transformers torch

Inference

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

tokenizer = AutoTokenizer.from_pretrained("lostelf/scibert_scicite_finetuned")
model = AutoModelForSequenceClassification.from_pretrained("lostelf/scibert_scicite_finetuned")

text = "We use the BERT architecture as in Devlin et al."
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=256)

with torch.no_grad():
    outputs = model(**inputs)
    logits = outputs.logits
    predicted_class = logits.argmax(dim=-1).item()

labels = {0: "background", 1: "method", 2: "result"}
print(f"Predicted: {labels[predicted_class]}")

Batch Prediction

texts = [
    "We build on the transformer framework introduced by Vaswani et al.",
    "Our implementation follows the optimization procedure in Kingma & Ba.",
    "These results exceed prior work by Devlin et al. (BERT)."
]

inputs = tokenizer(texts, return_tensors="pt", padding=True, truncation=True, max_length=256)
outputs = model(**inputs)
predictions = outputs.logits.argmax(dim=-1)
print([labels[p] for p in predictions])
