#### Question over at Meta Discourse

My idea is that you’d have a plugin where you can moderate posts and it automatically trains a text classifier to learn from your moderation. For example, if you mark a post as having toxic language or being off-topic it learns from you and can flag similar posts or even pre-moderate them.

Text classifiers (used in forums, for example) have been around for a long time.

Typically this type of text classification and scoring is performed with Bayesian classifiers.

If you do a Google search with keywords:

```plaintext
bayesian classifier ruby

```

and /or

```plaintext
bayesian classifier javascript

```

You will find myriad libraries and examples of text classification using Bayesian classifiers.

We have used various Bayesian classifiers for forum post moderation, spam detection, and more over the years; and have implemented custom code to train the classifier when moderators perform mod actions.

Hope this helps.
