Ander Barrena, Aitor Soroa, Eneko Agirre · 2015
Named entity disambiguation is the task of linking entity mentions to their intended referent, as represented in a Knowledge Base, usually derived from Wikipedia.In this paper, we combine local mention context and global hyperlink structure from Wikipedia in a probabilistic framework.Our results show that the two models of context, namely, words in the context and hyperlink pathways to other entities in the context, are complementary.We test our method in eight datasets, improving the state-of-the-art results in five, without any tuning, showing that it is robust to out-ofdomain scenarios.When tuning combination weights, we match the best reported results on the widely-used AIDA-CoNLL test-b.
