bisac_expanded_topics

This is a list f 34,000 topics based on the BISAC book classification, a standard used to categorize books by subject that is both comprehensive and educationally focused.
We started with 5,000 topics belonging to 51 categories in [BISAC](https://www.bisg.org/complete-bisac-subject-headings-list) (`top_category` and `subcategory`) and asked Mixtral to generate subtopics for certain topics.
Below is the final distribution of subtopics in each category (the prompts and generations are available in the dataset):
