Implementation on machine learning with weka

[david4u]

Goodday,
I am new to weka and I am working on machine learning algorithm in Emails. How I can group emials based on user activities and also to provide text sumarization.

Can someone explain or put me through how I can use weka to sort out part of this task?

Sounds a bit like text mining in conjunction with clustering. These links might help a bit:
