We evaluated our method with a set of 200 query persons randomly selected from Baidu 1 query logs, and compare it with Renlifang 2 , a well known system developed for related person extraction.
experiment results show that our approach consistently outperforms Renlifang with a gap of 8%-13% in terms of averaged P recision@K. 8.28% (0.915 vs. 0.845), 12.9% (0.9 vs. 0.797), and 9.73% (0.846 vs. 0.771) improvement has been achieved at rank 1, 5, and 10 respectively.
