Possessive vs non possesive WH-pronouns

Question

I was going through Jurafsky book. It says following about pronouns in the context of tag set:

Wh-pronouns (what, who, whom, whoever) are used in certain question forms, or act as complementizers (Frida, who married Diego...).

But there are two categories for Wh-pronouns in Penn tagset:

• WP: Wh-pronoun
• WP$: Possissive wh-pronoun

I was guessing which Wh-pronouns are possessive and which are not. I feel only "whose" is possessive and rest all (which, where, who, whom etc) are not possessive. Am I correct with this?

Answer 1

You are right. There only 'whose' is possessive:

The tag for WHOSE is WPRO$.

he_PRO asked_VBD hir_PRO ... whos_WPRO$ was_BED the_D child_N within_P her_PRO$ body_N

and_CONJ by_P whoos_WPRO$ commandement_N
