Experiments with ACE 2004 Semantic Relations

In this paper are presented two semantic relation classication ex- periments: one with 7 and one with 3 semantic relation classes. The comparison between the results of the experiments reveal that the pro- posal of 3 semantic relation classes (Role, Location and Social) is a good generalization and it leads to an F-measure of 0.80 using support vector machines and 0.81 using decision trees.
