This primer will take a deep dive into NLP, NLU and NLG, differentiating between them and exploring their healthcare applications.
Differentiating NLP, NLU and NLG NLP, NLU and NLG are related, but distinct concepts.
Using machine learning (ML) and deep learning techniques, NLP converts unstructured language data into a structured format via named entity recognition (NER).
NLU tools analyze syntax -- the grammatical structure of a sentence -- and semantics -- the intended meaning of the sentence.
NLG tools typically analyze text using NLP and considerations from the rules of the output language, such as syntax, semantics, lexicons and morphology.
