2.1 Deﬁnitions
We represent a Knowledge Base K as a set of triples
(s, r, o) where s, o ∈ E are the subject and object
entities and r ∈ R is the relation, where E and
R are pre-deﬁned vocabularies of entities and rela-
tions. A text corpus C is a collection of paragraphs2
{p1, . . . , p|C|}. Let M be the set of entity men-
tions in the corpus C. A mention mi is encoded
as (em, sp
m), indicating entity em is mentioned
in paragraph p starting at token position sp
m and
ending at tp
m. We will usually drop the superscript
p and use sm and tm for brevity.
