Explicitness of Declarative Chunks

[Jerry.Ball at williams.af.mil]

are consciously aware of the contents of declarative chunks and can reflect
on their content.  However, it is not clear to me that the "type" of a
declarative chunk is something that can necessarily be reflected on. Thus,
if a human has a declarative chunk type  "ISA noun", it is not necessarily
the case that the human can reflect on that type. Humans may know that words
belong to various categories without explicitly being able to reflect on
what those categories are. If, on the other hand, the Part of Speech of a
word is encoded in a slot with the type of the declarative chunk being
something like "ISA word", then the same argument holds for the slot
containing the POS. 

For example, given

(man isa noun
   word man)

or

 (man isa word
     word-form "man" 
     word-root man 
     word-type noun)

Although the type "noun" is encoded in the declarative chunks, knowledge of
the type "noun" remains implicit.
