The goal of this ILP is to find a set of assignments for all z ia that maximizes the following function: Each S i ∈ S should have one of these argument types, or no type (null).
we have Next, we show how to transform the constraints in 1 http://homepages.inf.ed.ac.uk/s0450736/maxent_toolkit.html the filter function into linear equalities or inequalities, and use them in this ILP.
