I think email spam detection is an interesting and important 
problem. It affects everyone and obviously not very well 
solved yet. It is also quite chanllenging since it is non-
trivial to predict whether an email is a spam or not. The 
feature selection is not straightforward, due to the 
possible large quantities of term or term combinations, and 
the possible variations / evolvements of patterns. Also, it 
is not clear that what are the very effect classification 
method. 

Users: everyone.
Data: emails.
Functions: classification.
