As Tino says, the emphasis is SMT learns from data and RBMT learns from
linguist. However, the distinction can sometime blur and we borrow each
other's ideas.
For instance, you might need linguistic knowledge to manually write
reordering rules in SMT. In Moses, we've added placeholders for
numbers/dates/name translation since manually written rules are best at
translating these.
And I'm sure RBMT has bits and pieces from SMT. Whatever works for you
