• Usually text input, especially in e-mail and some related occasions, in addition to the validation of spelling, structure of words, maybe only the text grammar structure. For the proper use of those and whether there is profanity-level statements, currently rarely integrated into related applications.
• Using machine learning to construct related models can strengthen the test of whether the content of the text is appropriate.
• This repo shares a trained model and an open API for validation on the phrase, free to integrate in an English based app.

🚨WARNING🚨

For the demo and explanation purpose, this repository, all examples and data referenced may contain content which can be uncomfortable, please forgiven.

!!! rm "rewrites" node in firebase.json
$ firebase deploy --only hosting

• An open table from tweet feeds and classified by three types.
  • 0 - hate speech 1 - offensive language 2 - neither.
  • Download http://tinyurl.com/y8ylg8zo
• Use Google Cloud Tables(AutoML) to train the model.
• Deploy and host model on Google Cloud.
  • Mirror download http://tinyurl.com/y824odfu

• A REST-API: https://profanity-check-c9365.web.app/profanityCheck2?q=[phrase you want to validate]

Example

https://profanity-check-c9365.web.app/profanityCheck2?q=hello

Output
