Professionalism Rating Model

This repository contains the model described in the paper Meta-rater: A Multi-dimensional Data Selection Method for Pre-training Language Models .

Code: https://github.com/opendatalab/Meta-rater

Model Description

This model is a fine-tuned version of ModernBERT-base designed to evaluate the Professionalism dimension of text quality on a 5-point scale (0-5). Professionalism measures the degree of expertise and prerequisite knowledge required to comprehend a text, focusing on the depth, accuracy, and accessibility of content.

Model Details

• Base Model : ModernBERT-base
• Parameters : 149M
• Context Window : 4,096 tokens
• Task : Text quality rating (regression)
• Score Range : 0-5 (continuous)
• Performance : 91.57% F1 score, 93.78% accuracy

Rating Scale

The model uses an additive 5-point rating system:

• 0 : Content requiring no technical knowledge
• 1 : Simple content requiring minimal technical knowledge (nursery rhymes, children's books)
• 2 : Somewhat complex content requiring basic specialized knowledge (popular books, popular science)
• 3 : Moderate complexity requiring some expertise (advanced books, detailed articles)
• 4 : Complex content requiring significant expertise (academic papers, technical reports)
• 5 : Extremely high professionalism requiring advanced subject matter expertise (advanced academic papers, patents)

Usage

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

# Load the model and tokenizer
model_name = "opendatalab/meta-rater-professionalism-rating"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)

# Example text
text = "The quantum entanglement phenomenon demonstrates non-local correlations between particles..."

# Tokenize and predict
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=4096)
with torch.no_grad():
    outputs = model(**inputs)
    score = outputs.logits.squeeze().argmax(dim=0)

print(f"Professionalism Score: {score:.2f}")

Training Details

• Training Data : 747,422 examples from SlimPajama dataset
• Annotation Model : Llama-3.3-70B-Instruct
• Training Epochs : 10
• Evaluation Split : 93,428 test examples
• Data Split : 8:1:1 (train:dev:test)

Applications

This model is particularly useful for:

• Data curation for language model pre-training
• Content filtering based on technical complexity
• Educational content difficulty assessment
• Research paper and technical document evaluation
• Curriculum development and content sequencing

Limitations

• The model focuses on content professionalism, not writing style or grammar
• Performance may vary across different domains not well-represented in training data
• Designed primarily for English text
• Should not be used as the sole criterion for content quality assessment
