Purpose of ESTA

Hello,

What is the purpose of ESTA? Do you know any Text to Graphics conversion software?

Thanks.

ESTA is almost 20 years old. It can search a state-space (of text symbols) chaining forward, and chaining backwards.
The 'states' in the stae space consist of 'sections.' Within a 'section' you can establish, dentify (or discard) parameters by 'backward chaining,' which corresponds roughly to the prolog backtracking mechanism. This way, you can 'move forward' from section to section, thus implementing 'forward chaining state space search.'
The terminology of searching state spaces is explained in traditional texts like Bratko, C&M, etc.
Cheers,

Oh, i forgot: while you can do all this programatically with Visual Prolog code, ESTA is a high-level 'shell,' which can be used by non-programmers too. You just populate the generic 'shell' with domain-specific facts and rules.
(My) experience indicates that these kinds of expert systems have very limited use. But for instance the 'so called' help experts that you'll find attached to many hardware components may constitue a well known example. For instance look at 'Windows network connection helper.'

If it is so as is described by you then why it is named ESTA? _, _, Text Animation? Where is that animation? And if i need Text Animation or Text to Graphics conversion using porlog, what is the way?

Please think about ESTA as one of the examples of an expert system

Animaiton word just subscribes, that you can see pictures while expert system journey

Being part of the commercial edition implies that it is not free.

as to CLIPS: Are you referring to the C Language Inference Production System?

if yes, there is a VBX (OCX ?) plug-in available for purchase. I used it it about 10 years ago for particular expert system where the customer specified I had to use CLIPS. I am not sure if it is still available on the market though and I no longer have a copy of it.

here is the last link to it that I knew about it.

I used Haley's VBX OCX product way back in 1996. It was replaced by other Haley Limited products for embedding rules. It is no longer available. CLIPS though is still being developed by Gary Riley at http://clipsrules.sourceforge.net/.

With VBX I recall creating the rules in a text file (CLP) and passing data back and forth form Visual Basic to the VBX engine via a callback routine (not particularly elegant). The same thing could be done compiling CLIPS to a DLL and linking from Visual Prolog. I am not sure if this comment is still relevant but I thought I would add it anyway.

Also for anyone interested, Paul Haley started another company, Automata Inc, and he has a professional blog at http://haleyai.com/wordpress/ (Oracle eventually bought out Haley Limited). One of Paul's recent posts is entitled "Confessions of a production rule vendor. Part 1" in which he talks about the diminishing adequacy of production rules. He goes on to ask the question why BRMS do not use Prolog and that he believes the use of Prolog is on the rise (albeit IBM Watson Prolog - see http://www.cs.nmsu.edu/ALP/2011/03/natu ... on-system/). Okay, now I am rambling ...
