Epistemic NP Modifiers
The paper considers participles such as "unknown", "identified" and
"unspecified", which in sentences such as "Solange is staying in an unknown
hotel" have readings equivalent to an indirect question "Solange is staying in
a hotel, and it is not known which hotel it is." We discuss phenomena including
disambiguation of quantifier scope and a restriction on the set of determiners
which allow the reading in question. Epistemic modifiers are analyzed in a DRT
framework with file (information state) discourse referents. The proposed
semantics uses a predication on files and discourse referents which is related
to recent developments in dynamic modal predicate calculus. It is argued that a
compositional DRT semantics must employ a semantic type of discourse referents,
as opposed to just a type of individuals. A connection is developed between the
scope effects of epistemic modifiers and the scope-disambiguating effect of "a
certain".Comment: Final pre-publication version, 27 pages, Postscript. Final version
