Query: An HPSG Parser Based on Description Logics   In this paper I present a parser based on Description Logics (DL) for a
German HPSG -style fragment. The specified parser relies mainly on the
inferential capabilities of the underlying DL system. Given a preferential
default extension for DL disambiguation is achieved by choosing the parse
containing a qualitatively minimal number of exceptions.
