Automatically extracting topics from large amounts of text is one of the main uses of natural language processing (NLP). The latent Dirichlet allocation (LDA) technique is frequently used to extract topics from pre-processed materials based on word frequency. One of the main problems of LDA is that the topics extracted are of poor quality if the do...
