ILP provides a framework for jointly determining anaphoricity and coreference decisions for a given set of mentions based on the probabilities provided by P A and P C , such that the resulting joint decisions satisfy the desired constraints while respecting as much as possible the probabilistic decisions made by the independently-trained P A and P C .
an ILP program is composed of an objective function to be optimized subject to a set of linear constraints, and is created for each test text D as follows.
