Suppose that we now encounter a new entity pair (x, y) occurring with a phrase that matches p. We can compute the likelihood of x and y being of types t 1 and t 2 , respectively, from the likelihood of p cooccurring with entities of types t 1 , t 2 .
we are interested in the type-pattern likelihood, defined as follows: Definition 6 (Type-Pattern Likelihood) The likelihood of p co-occurring with an entity pair (x, y) of the types (t 1 , t 2 ) is given by: (1) where t 1 and t 2 are the types of the arguments observed with p from a corpus such as Wikipedia.
