NILC Portuguese Word Embeddings — Wang2Vec CBOW 50d

This repository contains the Wang2Vec CBOW 50d model in safetensors format.

About

NILC-Embeddings is a repository for storing and sharing word embeddings for the Portuguese language. The goal is to provide ready-to-use vector resources for Natural Language Processing (NLP) and Machine Learning tasks.

The embeddings were trained on a large Portuguese corpus (Brazilian + European), composed of 17 corpora (~1.39B tokens). Training was carried out with the following algorithms: Word2Vec, FastText, Wang2Vec, and GloVe.

📂 Files

• embeddings.safetensors → embedding matrix ([vocab_size, 50])
• vocab.txt → vocabulary (one token per line, aligned with rows)

🚀 Usage

from huggingface_hub import hf_hub_download
from safetensors.numpy import load_file

path = hf_hub_download(repo_id="nilc-nlp/wang2vec-cbow-50d",
                       filename="embeddings.safetensors")

data = load_file(path)
vectors = data["embeddings"]

vocab_path = hf_hub_download(repo_id="nilc-nlp/wang2vec-cbow-50d",
                             filename="vocab.txt")
with open(vocab_path) as f:
    vocab = [w.strip() for w in f]

print(vectors.shape)

Or in PyTorch:

from safetensors.torch import load_file
tensors = load_file("embeddings.safetensors")
vectors = tensors["embeddings"]  # torch.Tensor

📊 Corpus

The embeddings were trained on a combination of 17 corpora (~1.39B tokens):
