Ceci est une version annotée du script de base word2vec. Le code est basé sur un tutoriel Word2Vec fourni par Tensorflow.
Historique
Word2vec est constitué de modèles associés utilisés pour générer des vecteurs à partir de mots (aussi appelé plongement lexical). C'est un réseau neuronal à deux couches, produit par une équipe de chercheurs dirigée par Tomas Mikolov chez Google.
word2vec_basic_algolit.py
La structure du script word2vec annoté est la suivante:
- Étape 1: Télécharger les données.
- Algolit step 1: Lire les données du fichier texte brut
- Algolit inspection: wordlist.txt
- Étape 2: Créer un dictionnaire et remplacer les mots rares par un symbole UNK.
- Algolit inspection: counted.txt
- Algolit inspection: dictionary.txt
- Algolit inspection: data.txt
- Algolit inspection: disregarded.txt
- Algolit adaption: reversed-input.txt
- Étape 3: Fonction pour générer un lot de formation pour le modèle skip-gram
- Étape 4: Construire et former un modèle de skip-gram.
- Algolit inspection: big-random-matrix.txt
- Algolit adaption: sélectionnez votre propre ensemble de mots-test
- Étape 5: Commencer la formation.
- Algolit inspection: training-words.txt
- Algolit inspection: training-window-words.txt
- Algolit adaption: visualisation des mises à jour de calcul de similarité cosinus
- Algolit inspection: logfile.txt
- Étape 6: Visualisez les plongements.
- Algolit adaption: sélectionner 3 mots à inclure dans le graphique

Le script word2vec_basic.py fournit une option pour télécharger un jeu de données à partir de la page d'accueil de Matt Mahoney. Il s'avère être un document en texte brut, sans ponctuation ni saut de ligne. Pour les tests que nous voulions faire avec le script, nous avons plutôt opté pour un extrait de littérature académique: Tristes Tropiques, écrit par Claude Lévi-Strauss et traduit par John Russell. (https://archive.org/details/tristestropiques000177mbp).
Avant que nous puissions utiliser le texte de nearbySaussure comme matériel de formation, nous devions supprimer toute la ponctuation du fichier. Pour ce faire, nous avons écrit un petit script python text-punctuation-clean-up.py. Le script enregistre une version *dépouillée* du livre d'origine sous un autre nom de fichier.
Le livre contient 153.003 mots au total dont 19.869 mots sont uniques.
