Is it possible to predict two categories from one label?

Prentice

I'm new to this software and was wondering if this is possible or if it only categorizes it to the closest category.

For example, if I have a raw line written like: "My brother likes oranges as well as bananas" and I have the categories Orange, Banana, Apple and Pear.
Is it possible to categorize this into Orange as well as Banana?

Hi,

You could look at the confidence values and extract the top N predictions from those.  Or you could simply use the operator "Generate Prediction Ranks" which is doing exactly that for a given number of desired classes.  The process below shows a simple example.

Hope this helps,

Thanks, I will try this once I get to it.
