I Want Dataset For Topic Modeling In Json Format

I need dataset for this
Using the concept of topic modeling, implement it using:

(i) Rule-based method

(ii) Latent Dirichlet Allocation LDA method

For your convenience, take any unlabeled dataset

Perform data cleaning

Use TF-IDF vectorizer and any clustering method in case of Rule-based method

Fit LatentDirichletAllocation estimator in case of LDA method
