When evaluating the top 10 triples with the highest relevance weight, our framework outperforms the best baseline LDA by 4.4% in MAP and by 3.91% in P@N. When evaluating the top 5 triples, our framework performs even better and significantly outperforms the best baseline by 5.87% in MAP and by 17.21% in P@N. To analyze the results further, Ours-S, the simplified version of our model without iterative propagation, outperforms two strong baselines VSM and WE, which indicates the effectiveness of encoding distributional semantics.
the most closely related work in this area is our own (Zhang et al., 2014), which used the triples of SPO as background knowledge.
