Part 5: Comparison and Applications

In this part, you will understand how the ongoing development of LLMs has contributed significantly to topic modeling for document classification. You will learn about the BERTopic modeling, a milestone topic modeling method that adopts the BERT word embeddings. You will build a BERTopic model and understand its differences with LDA.

This unit then surveys seven NLP applications in the medical, healthcare, social media, legal, and finance fields. The techniques include Word2Vec, LSA, LDA, and BERTopic. In each use case, you will understand the professional background, the need for an NLP model, and their solutions.

This part contains the following chapters:

• Chapter 14, LDA and BERTopic
• Chapter 15, Real-World Use Cases
