... of a medical “event” in clinical text is very dif- ferent from events in Timebank. Medical events are temporally- associated concepts in clinical text that describe a medical condition affecting ... to rank medical events. Temporally ordering medical events allows us to induce a partial order of medical events over the patient’s history. We noted many d...

... to this function. Again, since our interest is in investigating the util- ity of the answer textual content, we use only infor- mation extracted from the answer text when learn- ing the scoring ... the cost of building the training corpus in the former setup is high; in the latter scenario the data tends to be domain-specific, hence unsuitable for the learning of open-domain models....

... methods. The main difference is that rather than trying to maximize a single metric, we maximize the number of pareto points, in order to expand the Pareto Frontier We will explain PMO-PRO in terms ... necessarily pareto-optimal. Algorithm 1 shows the pseudocode. In line 3, we take a point h ∗ and check if it is dominating or dominated in the for- loop (lines 4-8). At least one...
