These knowledge bases have been shown to form a valuable component for many natural language processing tasks such as knowledge base population , text classification (Wang and Domeniconi, 2008), and cross-document coreference (Finin et al., 2009).
to be able to utilize or enrich these KB resources, the applications usually require linking the mentions of entities in text to their corresponding entries in the knowledge bases, which is called entity linking task and has been proposed and studied in Text Analysis Conference (TAC) since 2009 (McNamee and Dang, 2009).
