In-Depth Information
The semantic relations and signature graphs of the iterated object sentence
construction 9.4.1 and the corresponding unbounded dependency 9.4.2 are the
same; both have the degree sequence 2221111 (disregarding the start line). The
only difference between the respective NAGs is in the object of the final object
sentence, i.e.,
To m
or
WH
. The dependency in 9.4.2 is between the surface-
initial WH and the object of the final object sentence; it is unbounded because
there is no limit on the number of intervening iterated object sentences.
The order of proplets in the following content representation of 9.4.2 follows
the NAG. Given that proplets are inherently order-free, they could just as well
be shown in the alphabetical order of the core values or in the surface order:

The verb proplet
say
has the arguments
John
and
(believe 7)
, the verb proplet
believe
has the arguments
Bill
and
(love 8)
, and the verb proplet
love
has the
arguments
Mary
and
WH
.
The verb proplets
believe
and
love
of the object sentences are opaque (Sect.
7.5) because they have an additional
fnc
attribute to serve as an argument of
their higher clauses. The values of these
fnc
attributes are addresses, specified
as the core and the
prn
value of the preceding higher verb, just as the
arg
attributes of the higher verbs specify the following subclause as an address
(bidirectional pointering).
Finally consider the surface realization of the unbounded dependency con-
struction based on the NAG in 9.4.2. The WH word is accessed and realized
by traversing arcs 3-6-9. This navigation is continuous, in line with 9.1.4, 3,
despite the nonconsecutive numbering. Then the auxiliary
did
is realized by
returning to
say
via arcs 10-11-12, relying on the usual
do-support
of English
WH constructions. From there, the realization from arc 1 to arc 8 resembles
that of the iterated object sentence construction 9.4.1. Omitting arcs 9 and 10,
the navigation returns to
say
via 11-12 to realize the fullstop.

Superficially, the signature in 9.4.1 may seem to resemble a Nativist Phrase Structure tree. However,
as explained in Sect. 7.1, the lines in a Phrase Structure tree indicate dominance and precedence,
whereas the lines in a DBS graph indicate the subject
