## Dataset Overview |
|
This dataset is based on [derek-thomas/dataset-creator-reddit-{subreddit}](https://huggingface.co/datasets/derek-thomas/dataset-creator-reddit-{subreddit}) |
|
and will add [nomic-ai/nomic-embed-text-v1](https://huggingface.co/nomic-ai/nomic-embed-text-v1) embeddings based on the |
|
`content` field. |
|
|
|
The goal is to be able to have an automatic and free semantic/neural tool for any subreddit. |
|
|
|
The last run was on {latest_hour_str} and updated {new_rows} new rows. |
|
|
|
## Creation Details |
|
This is done by triggering [derek-thomas/processing-bestofredditorupdates](https://huggingface.co/spaces/derek-thomas/processing-bestofredditorupdates) |
|
based on a repository update [webhook](https://huggingface.co/docs/hub/en/webhooks) to calculate the embeddings and update the [nomic atlas](https://docs.nomic.ai) |
|
visualization. This is done by this [processing space](https://huggingface.co/spaces/derek-thomas/processing-bestofredditorupdates). |
|
|
|
## Update Frequency |
|
The dataset is updated based on a [webhook](https://huggingface.co/docs/hub/en/webhooks) trigger, so each time [derek-thomas/dataset-creator-reddit-{subreddit}](https://huggingface.co/datasets/derek-thomas/dataset-creator-reddit-{subreddit}) |
|
is updated, this dataset will be updated. |
|
