You could try:
return strip_tags(self.cleaned_data['title'])
though I have no knowledge of what that function does so I'm just assuming
it does what you want.
There are several things wrong with what you have: first, stirp_tags is a
simple function, not an object method, and not a method of ArticleForm
(hence the error when you try to call it via self.strip_tags). Passing in
'title' will cause it to operate on the literal string 'title', whereas if
you want it to operate on the data that has been posted in the form, you
need to pass in self.cleaned_data['title']. You assign what it turns to the
variable title but then you go ahead and return the original
self.cleaned_data['title'] that you have not modified, so even if you did
not get the error you are seeing, your clean function as written would
simply return what had been included in the form.
