Bayesian text classification is often used for things like spam detection, sentiment determination, or general categorization. Essentially you collect samples of text that you know are of a certain "type" or "category," then you use it to train a bayesian classifier. Once you have trained the classifier with many samples of various categories, you can begin to classify and/or score text samples to see which category they fit best in. You could, for instance, set up classification of sentiment by finding samples of text that are happy, sad, angry, sarcastic, and so on, then train a classifier using those samples. Once your classifier is trained, you can begin to classify other text into one of those categories. What a classifier does is look at text and tell you how much that text "looks like" other categories of text that it has been trained for.

$ sudo nohup scentamint >> /var/log/scentamint.log 2>&1 &All endpoints accept POST commands and return predictable results depending on what is posted.
Endpoint:
/train/<string:category>/ (ex: /train/spam/)
Result Status:
204 No Content
- The POST payload should contain the raw text that will train the classifier.
- You can train a category as many times as you want.
Endpoint:
/untrain/<string:category>/ (ex: /train/ham/)
Result Status:
204 No Content
- The POST payload should contain the raw text that will train the classifier.
- You can untrain a category as many times as you want, but a token's value will not go below zero.
- This action carries out the inverse operation of training so unintentional trains can be reversed.
Endpoint:
/classify/
Result Status:
200 OK
Result JSON Example:
{
"result": "ham"
}
- The POST payload should contain the raw text that you want to classify.
Endpoint:
/score/
Result Status:
200 OK
Result JSON Example:
{
"scores": {
"ham": 268.4685238156538,
"spam": 44.531476184346225
}
}
- The POST payload should contain the raw text that you want to score.
Endpoint:
/flush/
Result Status:
204 No Content
- This is a purely destructive, non-reversable action.
