Model Card for Model ID

This model is designed to identify whether two product titles (including specifications) describe the same product. The model generates a score, where a score greater than 0.5 indicates that the products are likely the same. The threshold value can be used as needed. It is based on the BERT base uncased architecture and has been fine-tuned on a custom dataset derived from real-world examples. The model performs particularly well on longer sequences.

Model Details

Model Description

Model type: Binary Classification
Language(s) (NLP): English
Finetuned from model: bert-base-uncased

Uses

Direct Use

This model can be directly used to determine if two product titles are the same. It is especially useful in e-commerce applications for deduplication, catalog matching, and product comparison.

Out-of-Scope Use

The model is not suitable for tasks requiring deep contextual understanding beyond product titles or for comparing product descriptions that lack specification details.

Bias, Risks, and Limitations

Bias: The model may inherit biases present in the dataset, particularly related to product categories with less representation.
Limitations: The model is optimized for product titles and may perform poorly on short, ambiguous titles or non-standardized names.

Recommendations

It is recommended to use this model for products with clearly defined titles and specifications. Users should also monitor performance on specific product categories to identify and address any biases.

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

How to Get Started with the Model

python

import torch
from transformers import BertTokenizer
from huggingface_hub import hf_hub_download

# Step 1: Download model.py
file_path = hf_hub_download(repo_id='Berketarak/Product-Matching-Classifier', filename='model.py')

# Step 2: Add directory containing model.py to the Python path
import sys, os
model_dir = os.path.dirname(file_path)
sys.path.append(model_dir)

# Step 3: Import custom model class
from model import CustomBertModel

# Step 4: Load tokenizer and model
tokenizer = BertTokenizer.from_pretrained('Berketarak/Product-Matching-Classifier')
model = CustomBertModel.from_pretrained('Berketarak/Product-Matching-Classifier')

# Send model to GPU
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
model.to(device)

# Define the products
product1 = 'X brand Pegasus Sneakers'
product2 = 'Y brand Shoes'

# Tokenize the input
inputs = tokenizer(product1, product2, padding='max_length', truncation=True, max_length=350, return_tensors='pt')

# Inference
with torch.no_grad():
    input_ids = inputs['input_ids'].to(device)
    attention_mask = inputs['attention_mask'].to(device)
    token_type_ids = inputs['token_type_ids'].to(device)
    output = model(input_ids, attention_mask, token_type_ids).item()

# Interpret the output
if output > 0.5:
    print(f"The products are likely the SAME. Model output: {output}")
else:
    print(f"The products are likely DIFFERENT. Model output: {output}")
