  Within the categorical compositional distributional model of meaning, we
provide semantic interpretations for the subject and object roles of the
possessive relative pronoun `whose'. This is done in terms of Frobenius
algebras over compact closed categories. These algebras and their diagrammatic
language expose how meanings of words in relative clauses interact with each
other. We show how our interpretation is related to Montague-style semantics
and provide a truth-theoretic interpretation. We also show how vector spaces
provide a concrete interpretation and provide preliminary corpus-based
experimental evidence. In a prequel to this paper, we used similar methods and
dealt with the case of subject and object relative pronouns.
