In addition, our model shows results competitive with the best single models of the competition, while requiring no expensive hand-crafted features or external resources, thereby demonstrating its language and domain independence.
we show that the hierarchical model outperforms two non-hierarchical baselines, obtains results competitive with the state-of-the-art, and outperforms the state-of-the-art on five multilingual, multi-domain datasets without any handengineered features or external resources.
