Word2vec embeddings can be used for categorizing text by utilizing them as input features in a supervised classification algorithm. The following steps can be used for categorizing text using word2vec embeddings:
Preprocess the text: Remove stop words, punctuations, and any irrelevant information.
Generate word2vec embeddings: Train or download pre-trained word2vec embeddings.
Prepare the data: Convert text into numerical data using word2vec embeddings. You may take the average or sum of word vectors in a sentence to represent it.
Split the data: Split your data into training and testing datasets.
Train a classifier: Train a model such as logistic regression, SVM or Naïve Bayes using the word2vec embeddings as input features.
Evaluate the model: Evaluate the performance of the model on the testing dataset.
Fine-tune the model: Use hyperparameter tuning and cross-validation to optimize the performance of the model.
In summary, leveraging word2vec embeddings as input features in machine learning models can help categorize text accurately. This approach is commonly used in applications such as sentiment analysis, topic discovery, and document classification.
