Many Semantic Role Labeling (SRL) combination strategies have been pro- posed and tested on English SRL task. But little is known about how much Chi- nese SRL can benefit from system combi- nation. And existing combination strate- gies trust each individual system’s output with the same confidence when merging them into a pool of candidates. In our ap- proach, we assign different weights to dif- ferent system outputs, and add a weighted merging stage to the conventional SRL combination architecture. We also pro- pose a method to obtain an appropriate weight for each system’s output by min- imizing some error function on the devel- opment set. We have evaluated our strat- egy on Chinese Proposition Bank data set. With our minimum error weighting strat- egy, the F1 score of the combined ...
