Y2014-23_PFAS-Abstract_TM01

This is a BERTopic model. BERTopic is a flexible and modular topic modeling framework that allows for the generation of easily interpretable topics from large datasets.

Usage

To use this model, please install BERTopic:

pip install -U bertopic

You can use the model as follows:

from bertopic import BERTopic
topic_model = BERTopic.load("tempe2phoenix/Y2014-23_PFAS-Abstract_TM01")

topic_model.get_topic_info()
