An Introduction to Natural Language Processing (NLP)

This repository contains the code for the Introduction to Natural Language Processing presentation given at the Quera Data Science Bootcamp in November 2023.

Slides

Notebooks

1. Text processing: NLP_preprocessing.ipynb contains the code for the text processing part of the presentation.
2. Text representation: NLP_text_representation.ipynb contains the code for the text representation part of the presentation.
3. Naive Bayes: A from scrach implementation of the Naive Bayes classifier can be found in NLP_naive_bayes.ipynb.
4. Word Embeddings: NLP_word_embeddings.ipynb contains an exploration of word embeddings.
5. Song Recommender: We built a song recommender system using the idea of word2vec. The code for this part can be found in NLP_songs_recommandation.ipynb.
