# Use cases

The following pages will show you a walkthrough about three possible uses of SmartPredict's custom module features.

Let us see three simple use cases of custom modules to help you understand how to create a module of your own. 

* The first case of use that we are going to see is **image resizing**. 
* the second is **text cleaning**, 
* and the third, **extracting URLs from texts and website**s.

All of them , are common use cases of **Data Mining** and useful operations to learn.
