Entity Linking (EL) has received considerable attention in recent years. Given many name mentions in a document, the goal of EL is to predict their referent entities in a knowledge base. Traditionally, there have been two distinct directions of EL research: one focusing on the effects of mention?s context compatibility, assuming that ?the referent entity of a mention is reflected by its context?; the other dealing with the effects of document?s topic coherence, assuming that ?a mention?s referent entity should be coherent with the document?s main topics?. In this paper, we propose a generative model ? called entity- topic model, to effectively join the above two complementary directions together. By jointly modeling and exploiting the context compatibility, the topic coher...
