In that approach a Predicate~DRS (henceforth PDRS) serves as the representation of a verb phrase, as will be shown in an example now. Consider: Nancy likes a cat. (1) Betty does too. This discourse is interpreted as meaning that Nancy and Betty both like a cat (though not necessarily the same cat). The source clause, Nancy likes a cat, parallels the target clause Betty does too, where the subjects are parallel elements. The phrase does too represents a trace of the VP in the target clause. Klein's treatment of (1) is shown in (2). . | VP Ellipsis in a DRT-implementation Johan Bos Department of Computational Linguistics Faculty of Arts University of Groningen 716 9700 AS Groningen. Email 1 Introduction Klein Klein 1986 introduced Predicate-DRSs for the resolution of VP Ellipsis. In that approach a Predicate-DRS henceforth PDRS serves as the representation of a verb phrase as will be shown in an example now. Consider Nancy likes a cat. Betty does too. This discourse is interpreted as meaning that Nancy and Betty both like a cat though not necessarily the same cat . The source clause Nancy likes a cat parallels the target clause Betty does too where the subjects are parallel elements. The phrase does too represents a trace of the VP in the target clause. Klein s treatment of 1 is shown in 2 . X1 x2 Pl X1 Nancy 2 y 1 y2 cat y2 like yi y2 x2 Betty Pi x2 3 In the second sentence of 1 a do-anaphor appears that must be linked to a marker which has already been introduced into the universe of the DRS. The value of this marker which is Pl as we can see in 2 is constrained by the conditions associated with the previous VP in the discourse Klein 1986 . Following Klein we call Pl a predicate marker and the Sub-DRS that is associated with Pl a Predicate-DRS. To the domain of Pl a distinguished reference marker yi indicated by square brackets is added which plays the role of the individual in this case Xi which is applied to the predicate. This application can also be shown as a lambda expression 3 A yi cat y2 A like yi y2 xi In 2 the condition p2 x2 in the main DRS will apply the object x2 to the predicate and solve the do-anaphor in 1 . The scope of marker y2 is defined by the PDRS instead of the main DRS which allows that Nancy and Betty do not necessarily like the same cat. But this same feature introduces a problem for pronoun resolution. This problem occurs when pronouns refer to indefinite NPs which are in the universe of a PDRS and therefore inaccessible. Let US give an .
