[sci.lang] Ambiguous parsing

marshall@marshall.cs.unc.edu (Jonathan Marshall) (04/10/91)

I'm writing a paper on parsing of ambiguous patterns, such as certain
ones arising in ordinary language.  As an example, the utterances
"Gray chips" and "Great ships" can sound identical [Grossberg], but of
course they are parsed differently depending on context.

We might consider this to be a grouping problem.  The three sounds
"GRAY," "T," and "SHIPS" can be grouped syntactically as
(GRAY+T)(SHIPS) or as (GRAY)(T+SHIPS).

I am looking for a longer version of this same idea.  That is, can
someone come up with an English sentence or phrase that has 2 or more
possible word-level parsings?  These might obey either the pattern
(A)(B+C)(D+E)(F) or the pattern (A+B)(C+D)(E+F), for example.  The
exact length or the particular grouping patterns are not of great
importance to me.

Please e-mail to me.  If there is enough interest, I'll summarize to
the net.  The authors whose examples I use will be properly
acknowledged in my paper.

Thanks!
