See the idea in three steps
A simple illustration of the idea. Results depend on the model, training and app.
A familiar way to picture it
An analogy helps you understand the main idea. It is not a description of every technical detail.
A simple BERTopic example
A restaurant has 1,000 reviews. BERTopic can help group comments about food, price and service.
A café receives many written reviews.
The software groups reviews with similar subjects.
The owner reads the groups to see which issues keep coming up.
Is BERTopic the same as ChatGPT?
No. BERTopic organises collections of writing into topics. ChatGPT is an assistant you can talk to. A developer can use language models as part of a BERTopic project.
Where can I try it or learn more?
A developer usually sets it up. It is not a chat app.
A maker’s page or research page may explain the technology rather than provide a chat box. Available models, features and access can change.
A small activity for you
You do not need to memorise model sizes or write a program to understand this lesson. First explain the idea in your own words. If you want to build an app later, the official resources are your next step.
