In article <LERMAN.92Aug31101259@sunny.teknowledge.com> lerman@teknowledge.com 
takes exceptions to my remark, "Witness the demise of Teknowledge."

Webster gives one definition of demise as "a loss of position or
status."  During the AI heyday, Teknowledge stock traded in the low
20's.  The last time I checked, Cimflex/Teknowledge was trading at
13/16.  Teknowledge in its heyday employed well over 100 individuals
(I think it was closer to 200, but I'm not sure).  Now they employ
some 35.

I have a lot of respect for the 35 people left at Teknowledge; they
do good work.  But there really shouldn't be much disagreement that
the company is only a shade of its former self.

Hello all,

I am working on a kind of automatic translation program between
ancient greek (Aristoteles, New Testament) and german. I am still at
the beginning of german grammar definition (in prolog) which turned
out to be quite difficult (now I know, how hard my native language
must be to learn for foreigners). I think greek will be more easy. If
I don't manage to get my box speaking german, I'll try on english.
  But the main problem I think is to get the thousands of words I need
for the translation. So my QUESTION:

If YOU know about *any* dictionary (whatever language, best: ancient
greek to whatever) beeing available on the net or anywhere for free,
please inform me!

The kind of dictionary is not important, since I will compile it in
order to have a dictionary of just word stems. May be there are some
theological departments who have a greek/* dictionary. Latin would
also be great.

Any help is greately appreciated,
regards
-Gunther.

As I originally understood the problem, the coefficients were indeed all 1,
and the expressions were merely the sum of one or more variables.

But I now have a constraint of the form

	0  =<  Mn + 0.66*C  =<  1.1

(for the curious, Mn is the fraction of manganese in the alloy, and C is
the fraction of carbon).  And all my constants are rational, in that they
are only specified to (say) two sig. figs..

Linear programming is not in my limited repertoire of skills; I really
want to solve this problem (although not urgently); there are only about
ten variables, so less than optimally efficient solutions may be viable.

I see the regions as cuboids-with-the-corners-sliced-off in N-space,
and reckon that if all the vertices of one region lie inside all the
bounding planes of the other, then the one is completely enclosed.

But I'm resisting the temptation to improvise a solution, because I
want not only to get it right but also to be seen to be right (i.e.
"the problem is an instance of General Problem X", and "General
Problem X is solved by Algorithm Y").

I also want to compute the _intersections_ of regions.

Background: if a customer specifies an alloy, and this subsumes some
alloy in stock, then the stock item will suffice (stock alloys are also
regions, because composition is not known exactly).  If not, but if the
spec. intersects significantly with an established (popular) standard(s),
then we may make a quantity which satisfies the intersection, hence we
both satisfy the customer and put some in stock for future use.

I know this ain't leading-edge AI, but this is the most-relevant-group-
-wot-i-subscribe-to.  Let me know if it would benefit you or me to move
it elsewhere.

My company has a product called RTworks that works quite well on the Indigo.
It is a software development tool that has a client/server architecture that
is designed for developing applications for real-time analysis, interpretation
and display of data. One of the clients is an expert shell that supports
backward and forward chaining, object oriented programing with multiple
inheritance, focusing on a subset of rules, priorities and many other 
capabilities. The performance has been benchmarked at 10,000 rules per second
on a SPARC 2 platform. It is an open architecture and can be extended with 
your own C code or imbedded in other applications.

The other clients are a data acquisition module and a human computer interface
that provides a point and click environment. The server module provides inter-
process messaging and data passing. Clients can be purchased seperately.

that is required is that you have an electronic mail address that is 
accessible either directly on the Internet or via a gateway connected 
thereto (e.g., BITNET or NASAMAIL). To subscribe, simply send a 
single line message to listserv@cossack.cosmic.uga.edu saying 
SUBSCRIBE CLIPS-LIST (the hyphen is required).  The subject field is

According to what you said, it seems that AI Ph.D programs should
be renamed Ph.D programs in LISP programmming?
Unfortunately, as one of the earlier respondents points out,
AI applications nowadays do not need much of specialized AI programming
expertise. Any competent software engineer can do it.
Why pay more for a Ph.D?

No physicist has to be a "bloody good" car mechanic.
why do AI Ph.Ds have to be "bloody good" programmers?
Can we view AI more as  science, and less as engineering?

Charlie, you might pass this on to Steven.

The field of AI is going through re-evaluation due to advancement
in perspective of the subject matter. Also some stability has been
established with what currently exist so employment has basicly
found its top off point. This will change as this new perspective
evolves and the work load increases to fill the enormus process of
filling in the Knowledge Navigational Map. The reason little is
being talked about in open forums is due to competition. To gain
some insight into this new perspective check out what serious
research is going on reguarding the valid crop circles. I know
the subject of crop circles doesn't seem to be connected at first
glance but the serious research is. There is an overall direction
of universal laws being represented which may lead to algorythims
extreamly useful in AI.

> o what were the causes of AI Winter?

There used to be the time that AI PhDs were regarded not only as great
researchers but also as "bloody good programmers", today's AI PhD
graduates became virtually unemployable outside academia as the major
thrust of their research work shifted into the theoretical foundations
of AI, so they simply became "not so good logicians". In my opinion,
the current AI Winter is a direct result of practices by IJCAI and
AAAI conference (and journal) committees who promote the work by
neaties (theorists) rather than by scruffies (software engineers).

> o why has AI gone out of fashion in the US industrial sector?

Most of the hot-shot AI research is based on small, unscalable
problems. Lots of promise, lots of funds, and no delivery.  It seems
that people from outside of AI but who use some of the AI techniques
are much more successful, e.g. in databases, software engineering,
programming languages, etc. They develop applications which start big
and then the clever AI tricks are used to address very small, well
defined and narrow problems (embedded AI).

> o stories of AI professionals or recent graduates who are or have been
>   unemployed or underemployed due to AI Winter;

I have met a number of AI wizards who specialised to the extent of
total unemployability. Some people who were experts in non-monotonic
logic, belief revisions, or default reasoning but who could see no
practical application of their own work to solve any real problem,
even when using Expert System shells or an AI language. I met
graduates who believed that a 5000 line lisp program is big and many
more whose PhD was based on work amounting to mere 100s lines of code,
the so called demonstrations of concepts.
