Propositions with coreferenced arguments

In the following examples, the word that constitutes an argument which actually is referencing to another argument in the sentence. These referencing arguments are marked as "R-T", where T is the type of the referenced argument.


The               -                   (A1*            (A0*               *

Propositions with some discontinuous argument


In the following examples, some argument is split into many discontinuous phrases. Each of the non-head phrase is labeled with the "C-T" tag, where T is the label of the argument.

One             -                   (A1*

. - *


The argument realizing the verb (V) can also be split into many pieces, mosltly when dealing with phrasal verbs.

Fear            -                   (A0*

Propositions expressing coordination in arguments

In the following example, the proposition of the verb claim realizes the argument A1 many times through coordination.
