This paper introduces IQPs (Integer Quadratic Programs) as a way to model joint inference for the task of concept recognition in clinical domain. IQPs make it possible to easily in- corporate soft constraints in the optimization framework and still support exact global infer- ence. We show that soft constraints give statis- tically significant performance improvements when compared to hard constraints.
