“…While these choices allow fast run-time, they generally rely on the assumption that all surface forms of each entity are present as aliases in the KB. The performances of these systems degrade when dealing with domain-specific vocabulary (Munnelly and Lawless, 2018), local variations (Rovera et al, 2017), historical materials (Olieman et al, 2017; and, in general, challenges that emerge when performing EL on non-standard documents. 2 This subtask of EL, often referred to as candidate ranking (and selection), is mostly ignored when designing downstream systems, even though its significant impact on downstream NLP pipelines has been shown previously (Quercini et al, 2010;Hachey et al, 2013).…”
