Grice and Turing: Shall I compare thee to a summer's day?

By JLS
---- for the GC

I'd like to analyse in some detail so-called fragments of a 'conversation' with a machine. Can a machine 'implicate'?

In his essay, Turing

http://www.abelard.org/turpap/turpap.htm

gives a sample of such a conversation:

A: In the first line of your sonnet
which reads 'Shall I compare thee to a
summer's day', would not 'a spring day'
do as well?

B: It wouldn't scan.

A: How about 'a winter's day'?
That would scan all right.

B: But nobody wants to be compared
to a winter's day.

A: Would you say Mr. Pickwick reminds you of Christmas?

B: In a way.

A: Yet Christmas is a winter's day,
and I do not think Mr. Pickwick would
mind the comparison.

B: I don't think you're serious.
By a winter's day one means a typical
winter's day, rather than a special
one like Christmas.

A: Well, I AM being serious.

B: Get lost!

For programming a computer to produce and recognise a conversational implicature (and citing Turing, AM. Computing machinery and intelligence. Mind 59,

For a pesimistic account: "No context-sensitive automaton can ever master the rules of Grice's conversational implicature -- based as they are on heuristic
abductive and defeasible problem solving reasing patterns, but maybe it
will. Work by Reichmann, Grosz, etc.
