... way. Up to now no studies exist on how kernels for different types of parse trees may support each other. To tackle this we present a study on how those kernels for relation extractions can be com- bined. ... to combine two kernels. The fourth sec- tion details the experiments on a public benchmark dataset. We close with a summary and conclu- sions. 2 Kernels for Relation Ext...
