NLP Pipeline for Sentence Normalization, Word Embedding, Positional Encoding, and French Translation Using Hugging Face Transformers and NLTK
This code provides a complete workflow for text processing using Hugging Face Transformers and NLTK. It includes modules for sentence normalization, spelling correction, word embedding generation, positional encoding computation, and English-to-French translation.
- Python
- Jupyter notebook
- NumPy: For numerical operations.
- NLTK: For text processing and tokenization.
- Transformers: For a translation using the MarianMT model.
- Pandas: For data handling.
Tokenize the input sentence into words and convert all tokens to lowercase.
Use WordNet to find the correct spellings for each token. If a token matches a known word in WordNet, it is corrected to its canonical form. This helps in standardizing words before generating embeddings.
Create random numerical vectors (embeddings) for each token. These embeddings represent words in a high-dimensional space, capturing semantic relationships. In practice, you might/can use pre-trained embeddings, but for demonstration purposes, random embeddings are generated.
Compute positional encodings for each token. Positional encodings help models understand the order and position of words, which is crucial for interpreting sentence structure, especially in sequence models.
Use the "MarianMT" model to translate the normalized sentence from English to French. The model is pre-trained on a large corpus of bilingual text, allowing it to generate accurate translations. Tokenized input is fed into the model, and the output tokens are decoded to produce the translated sentence.
Collect and organize all results, including normalized tokens, embeddings, positional encodings, and translations, into a DataFrame.
