Finding methods of classes from the use case

Question

I know some nouns in the use case scenario are candidate to be class, for example member, customer, student ....

I can find such entities and some attributes of them, but my problem is that I can't easily find any method for these classes.

Which part of use cases are candidate for methods or functions of classes?

Please give some examples.
For example in a system for hospital, Patient or Doctor are classes, what are the functions for these classes?

Answer 1

If the nouns are the classes the verbs are the functions. In your use case the nouns presumably do things? These are the candidates for functions of the classes.
