“A bag-of-words is all you need,” some NLPers have decreed.

The bag-of-words language model is a simple-yet-powerful tool to have up your sleeve when working on natural language processing (NLP). The model has many, many use cases including:

  • determining topics in a song
  • filtering spam from your inbox
  • finding out if a tweet has positive or negative sentiment
  • creating word clouds
