Here, we describe our model that encodes information about the set of entities E using dense unified representation for linking (v e ∈ R d , ∀e ∈ E).
we use existing mentions in Wikipedia to encode the context ( § 3.1), textual descriptions from Wikipedia to encode background information ( § 3.2), and fine-grained types from Freebase as structured topical knowledge ( § 3.3).
