Gv Semanticsearch Dutch Cased

🚀 {MODEL_NAME}

This model is designed for sentence similarity tasks. It belongs to the sentence-transformers family, mapping sentences and paragraphs into a 768-dimensional dense vector space. This makes it highly useful for tasks such as clustering and semantic search.

🚀 Quick Start

This section provides two ways to use the model, with and without the sentence-transformers library.

✨ Features

• Feature Extraction: Maps sentences and paragraphs to a 768-dimensional dense vector space.
• Versatile Applications: Ideal for clustering and semantic search tasks.

📦 Installation

To use this model, you need to install the sentence-transformers library. You can install it using the following command:

pip install -U sentence-transformers

💻 Usage Examples

Basic Usage

If you have the sentence-transformers library installed, you can use the model as follows:

from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]

model = SentenceTransformer('{MODEL_NAME}')
embeddings = model.encode(sentences)
print(embeddings)

Advanced Usage

If you don't have the sentence-transformers library installed, you can use the model directly through the transformers library. The following is a detailed example:

from transformers import AutoTokenizer, AutoModel
import torch


#Mean Pooling - Take attention mask into account for correct averaging
def mean_pooling(model_output, attention_mask):
    token_embeddings = model_output[0] #First element of model_output contains all token embeddings
    input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
    return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9)


# Sentences we want sentence embeddings for
sentences = ['This is an example sentence', 'Each sentence is converted']

# Load model from HuggingFace Hub
tokenizer = AutoTokenizer.from_pretrained('{MODEL_NAME}')
model = AutoModel.from_pretrained('{MODEL_NAME}')

# Tokenize sentences
encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')

# Compute token embeddings
with torch.no_grad():
    model_output = model(**encoded_input)

# Perform pooling. In this case, max pooling.
sentence_embeddings = mean_pooling(model_output, encoded_input['attention_mask'])

print("Sentence embeddings:")
print(sentence_embeddings)
