In the realm of public procurement, accurately classifying contract notices is pivotal. The multilingual-CPV-sector-classifier brings cutting-edge technology to simplify this task, enabling you to efficiently categorize procurement descriptions across multiple languages. This guide will walk you through how to utilize this model effectively, with helpful insights and troubleshooting tips included!

Understanding the Multilingual CPV Sector Classifier

The multilingual CPV sector classifier is a fine-tuned model based on bert-base-multilingual-cased. It effectively categorizes procurement descriptions written in over 104 languages into 45 sector classes, which are based on the Common Procurement Vocabulary (CPV). Think of it like a multilingual librarian who can understand various languages and direct different procurement notices to their correct shelves.

Getting Started

• Input Description: Ensure that your procurement descriptions are written in one of the 104 supported languages.
• Model Evaluation: Keep in mind that the model has only been evaluated in 22 languages—performances in others might be less reliable.
• Limited Scope: This model primarily caters to awarded procurement notices within the European Union, so results in different contexts may vary.

Training Procedure

The training of the multilingual classifier took place on Google Cloud V3-8 TPUs. Here’s a simplified view of the training parameters used:

learning_rate: 2e-05
num_epochs: 3
gradient_accumulation_steps: 8
batch_size_per_device: 4
total_train_batch_size: 32

Think of this setup like a baker meticulously perfecting a new recipe. Each parameter is an ingredient that, when mixed just right, results in the ideal batch of cookies—or in this case, an outstanding classification model!

Evaluating Model Performance

After training, the model’s performance is assessed using the F1 score, which balances the binary classification results of precision and recall. The final results showed an F1 score of 0.686, proving the model’s effectiveness in classifying procurement notices.

Troubleshooting Tips

If you encounter issues while using the multilingual CPV sector classifier, consider the following troubleshooting ideas:

• Input Issues: Ensure that the procurement descriptions are clear and compliant with the supported languages.
• Limited Language Performance: Be aware that the model’s reliability is limited to the 22 evaluated languages; performances in others might not be as strong.
• Domain Restrictions: Remember that the model focus is on EU procurement notices; using it for other regions may yield unexpected results.
