# SentenceTransformer based on sentence-transformers/paraphrase-multilingual-mpnet-base-v2
This is a [sentence-transformers](https://www.SBERT.net) model specifically trained for job title matching and similarity. It's finetuned from [sentence-transformers/paraphrase-multilingual-mpnet-base-v2](https://huggingface.co/sentence-transformers/paraphrase-multilingual-mpnet-base-v2) on a large dataset of job titles and their associated skills/requirements across multiple languages. The model maps English, Spanish, German and Chinese job titles and descriptions to a 1024-dimensional dense vector space and can be used for semantic job title matching, job similarity search, and related HR/recruitment tasks.
The model was presented in the paper [Multilingual JobBERT for Cross-Lingual Job Title Matching](https://huggingface.co/papers/2507.21609).
## Model Details
### Model Description
- **Model Type:** Sentence Transformer
- **Base model:** [sentence-transformers/paraphrase-multilingual-mpnet-base-v2](https://huggingface.co/sentence-transformers/paraphrase-multilingual-mpnet-base-v2)
- **Maximum Sequence Length:** 64 tokens
- **Output Dimensionality:** 1024 dimensions
- **Similarity Function:** Cosine Similarity
- **Training Dataset:** 4 x 5.2M high-quality job title - skills pairs in English, Spanish, German and Chinese
### Model Sources
- **Documentation:** [Sentence Transformers Documentation](https://sbert.net)
- **Repository:** [Sentence Transformers on GitHub](https://github.com/UKPLab/sentence-transformers)
- **Hugging Face:** [Sentence Transformers on Hugging Face](https://huggingface.co/models?library=sentence-transformers)
### Full Model Architecture
```
SentenceTransformer(
(0): Transformer({'max_seq_length': 64, 'do_lower_case': False}) with Transformer model: XLMRobertaModel
(1): Pooling({'word_embedding_dimension': 768, 'pooling_mode_cls_token': False, 'pooling_mode_mean_tokens': True, 'pooling_mode_max_tokens': False, 'pooling_mode_mean_sqrt_len_tokens': False, 'pooling_mode_weightedmean_tokens': False, 'pooling_mode_lasttoken': False, 'include_prompt': True})
(2): Asym(
(anchor-0): Dense({'in_features': 768, 'out_features': 1024, 'bias': True, 'activation_function': 'torch.nn.modules.activation.Tanh'})
(positive-0): Dense({'in_features': 768, 'out_features': 1024, 'bias': True, 'activation_function': 'torch.nn.modules.activation.Tanh'})
)
)
```
## Usage
### Direct Usage (Sentence Transformers)
First install the Sentence Transformers library:
```bash
pip install -U sentence-transformers
```
Then you can load and use the model with the following code:
```python
import torch
import numpy as np
from tqdm.auto import tqdm
from sentence_transformers import SentenceTransformer
from sentence_transformers.util import batch_to_device, cos_sim
# Load the model
model = SentenceTransformer("TechWolf/JobBERT-v3")
def encode_batch(jobbert_model, texts):
features = jobbert_model.tokenize(texts)
features = batch_to_device(features, jobbert_model.device)
features["text_keys"] = ["anchor"]
with torch.no_grad():
out_features = jobbert_model.forward(features)
return out_features["sentence_embedding"].cpu().numpy()
def encode(jobbert_model, texts, batch_size: int = 8):
# Sort texts by length and keep track of original indices
sorted_indices = np.argsort([len(text) for text in texts])
sorted_texts = [texts[i] for i in sorted_indices]
embeddings = []
# Encode in batches
for i in tqdm(range(0, len(sorted_texts), batch_size)):
batch = sorted_texts[i:i+batch_size]
embeddings.append(encode_batch(jobbert_model, batch))
# Concatenate embeddings and reorder to original indices
sorted_embeddings = np.concatenate(embeddings)
original_order = np.argsort(sorted_indices)
return sorted_embeddings[original_order]
# Example usage
job_titles = [
'Software Engineer',
'高级软件开发人员', # senior software developer
'Produktmanager', # product manager
'Científica de datos' # data scientist
]
# Get embeddings
embeddings = encode(model, job_titles)
# Calculate cosine similarity matrix
similarities = cos_sim(embeddings, embeddings)
print(similarities)
```
The output will be a similarity matrix where each value represents the cosine similarity between two job titles:
```
tensor([[1.0000, 0.8087, 0.4673, 0.5669],
[0.8087, 1.0000, 0.4428, 0.4968],
[0.4673, 0.4428, 1.0000, 0.4292],
[0.5669, 0.4968, 0.4292, 1.0000]])
```
