Dear Juan,
Yes, you are welcome to use it in your book. I really appreciate your
asking for permission. I have seen it used as university course
material in the U.S. without permission, even without an
acknowledgement. I was never even sent an excerpt of the thesis that
used it as an example. I received a request for help in building an
expert system from someone who claimed no knowledge of such things and
he sent his request (in broken English) from a Third World country.
Upon investigation, I discovered that he was actually an employee of
an American AI company (with a perfect grasp of English!) The ultimate
insult was a "demand" from an employee of Lockheed-Martin to reveal
the method and structure so that they could use it. Despite the fact
that they are one of the world's richest high-tech corporations, they
did not offer any compensation for my effort. I simply replied that I
did it in HTML.
If you would like a Word file of the paper version (18k), I can send
it to you as an attachment. It will appear on page 99 of my
forthcoming book. It is in A4 format.
Some other matters about this system that you might find interesting,
or perhaps useful, and are not explicit in the system:
1) It is non-hierarchical. The definitions that precede the answer to
some groups do not define these groups and might be shared with other
groups. These other groups are previously eliminated in the tree.
2) I tested the paper version on various people of different ages, and
with varying levels of knowledge about the coins. I used real coins in
this test instead of the photographs or line drawings in the on-line
system. The fastest time was less than one minute per coin and was
achieved by a 9 year old girl who had never seen an ancient coin
before. The slowest time (and an incorrect result) was made by an
experienced coin dealer who had actually sold me some of the
specimens. He tried to "cheat" the system by looking ahead in the tree
instead of following the steps as per the instructions. Recognizing an
element, he mis-identified the group because of the nature of the
system mentioned above in note 1.
3) I picked design elements (wherever possible) that were closest to
the centre of the coin, as these coins are often mis-struck and parts
of the outer design are often off the coin. This was not possible when
the chariot driver needed to be used, and coins that do not show this
feature might only be classified by their class and perhaps a limited
number of groups.
4) I was inspired to create this "Quick Identification Chart" (before
I knew what an expert system was) by an identification guide for
Egyptian scarabs in Sir W. M. Flinders Petrie's _Scarabs and Cylinders
with Names_. 1917. Chapter II, The varieties of scarabs. He provided a
list of features of the back with illustrations for each type, and a
corresponding range of dynasties in which they appear. I later found
out that the thought processes one experiences in using his guide
emulates an expert system. I just decided to formalize the method in
the fewest possible steps and apply it to my coins.
I will be happy to provide any other information that you need.
Kind regards,
John
