Web Based Expert System Using CLIPS

[Prana Adikhrisna]

Hi, i would like to ask a few question?

1) I want to make a web based expert system, can you tell me which
language/library I can use along with CLIPS/WebCLIPS or any other
library using CLIPS?
2) Can I use a CLIPSNet library in ASP.NET? (It has a server-side C#
code behind the .aspx file)
3) Can anyone suggest any good references/documentations/books for
creating a web based expert system with CLIPS/WebCLIPS?

Hello Prana

I use the library for PHP Phlips:
http://phlips.sourceforge.net
I have some examples that could help.
Another possibility is to run Jess code in Java (Web Services).

Bye

Thank you for the suggestion. Where can I get those examples? And also
can you suggest me any good reference/books on developing using
PHLIPS?

Once again, thanks

Hello Prana

Sorry about late...

1) Instalation
This tutorial is based on the document of my current host (MediaTemple.net):
http://kb.mediatemple.net/questions/1682/Installing+PECL+extensions
You can install from the PECL repository, but the package is outdated
CLIPS - still in version 0.5.0:
http://pecl.php.net/package/clips

Therefore, I recommend getting the source of the latest version of the
extension from the official site.
First, you need to access the server console. Then type:
wget http://phlips.sourceforge.net/downloads/clips-0.5.1.tar.gz
tar -xzf clips-0.5.1.tar.gz
cd clips-0.5.1
phpize5
./configure --with-php-config=/usr/local/php-5.x.x-x/bin/php-config
Obs.: replace php-5.x.x-x the installed version of PHP
make
cp modules/*.so ~/data/lib/php/

Note: if something goes wrong in the creation of the module, add the
directory where you will find the sources and type:
make clean
Redo the whole process with the necessary adjustments.

Edit php.ini and add the lines:
extension_dir = /home/xxxxx/users/.home/data/lib/php
extension = clips-0.5.1.so

Restart the web server, create a test page containing the phpinfo();
and make sure the extension is displayed.

2) Use
View this file:
http://www.de-sid.com/desid.clp
It contains the engine of a quiz.

PHP reads and execute all the rules available on the "agenda".
An example usage would be:
<?php
clips_set_strategy(LEX_STRATEGY);
clips_batch("rules.clp");
clips_load_facts_from_string($_SESSION['facts']);
clips_run();
?>

Each reload, you insert new rules (coming from the session, for
example) and submitt clips of the changes.
For the point of execution of PHP in accordance with the CLIPS I
recommend use global variables:
CLIPS file:
(defglobal ?*rule-triggered* = 0)

PHP file:
$_SESSION['RuleTriggered'] = clips_get_defglobal_value("rule-triggered");

Good luck!

phlips?

CLIPS has provided a CGI example.

It uses the latest CLIPS with batch command.

i want to ask, do you have toturial how to add new rule?

[Ari Stopassola Junior]

Hello Muhammad

First of all I load the CLIPS code base (clips_batch function), load some extra facts (based on that circumstance through clips_load_facts_from_string), execute (clips_run) and retrieve some new value with clips_get_defglobal_value.
Example:

<?php
//Clear the CLIPS environment
clips_clear();

//Set the conflict resolution strategy
clips_set_strategy(LEX_STRATEGY);

//Load and evaluate the commands stored in rules.clp
clips_batch("rules.clp");

//Position in the beginning
clips_reset();

//Sets the current focus to the specified module
//You must get each module, otherwise they do not load :-(
clips_focus("EXPLANATIONS");
clips_focus("ENABLED");
clips_focus("COLLECTNOTRESPONSE");

//Connect to database and fetch the facts, like:
$facts_DB .= "(resp ".$linha['cod_pergunta']." ".$idx." ".$valor.")\n";
//Load the facts from database to RETE
clips_load_facts_from_string($factos_BD);

//Load the spare fact
clips_assert("(ultima-pergunta ".substr($_SESSION['pergunta_atual'],1).")");

//Execute
clips_run();

//Retrieve the value of a defglobal for use in PHP script
$naorespondidas = clips_get_defglobal_value("MAIN::Perguntas-NaoResp");

//Load some data in PHP session
$_SESSION['perguntas_naoresp'] = clips_get_defglobal_value("MAIN::Perguntas-NaoResp");
?>

If you need some help to compile PHLIPS on version 5.4, 5.5 and 5.6 - use the code available in my tutorial:
https://github.com/stopassola/phlips
Actually I'm working to adapt the extension to PHP7...

Hi Ari.

I need to make an expert system in PHP7,

Can you adapt the PHlips in the PHP7 version?

[CLIPS Support]

There hasn't been any activity on PHlilps for years, so if you want it running on PHP7 you will probably have to adapt it yourself.
