Support for possessives

[assaft]

We want to support inferences like:
(note: 'of' is assumed to be annotated as OF unless differently specified)

Text=John's wife adores Paul.
Hypothesis=The wife of John adores Paul.

Text=Paul hates John's wife.
Hypothesis=Paul hates the wife of John.

Text=Paul hates John's wife, Yoko Ono.
Hypothesis=Paul hates Yoko Ono.

Text=Paul hates John's wife, Yoko Ono.
Hypothesis=Paul hates the wife of John.
'of' is assumed to be annotated as OF.

// for testing the internal representation only (as H is ungrammatical):
Text=Sue hates John's dog.
Hypothesis=Paul hates the dog of John.
Note: here 'of' is assumed to be annotated as P_R
