hi all,
iam having a very "strange" problem:
iam parsing values from java to jess by using:
fInfo.setSlotValue("certainty", new
Value(Float.parseFloat((String)info.elementAt(2)), RU.FLOAT));
the info-vektor is a string vector, sometimes elements of the string are
floats, therefore i chose the
HI Everyone:
After Jess starts to run, is there anyway to assert new facts in Java, and
fire the rules in Jess environment ?
For example:
===
Rete r;
//... Loads and parses CLIPS files
r.run();
r.executeCommand("(assert (yes))");

You've put an extra set of parentheses around the arguments to create$
-- Jess functions don't enclose their argument lists in parentheses.

Hello jess-users,
I am seeking for educational examples for the Jess, CLIPS or other
expert systems in a busines-consulting area. Can someone point me
out links to such materials? Thanks in advance.

Could you describe more precisely what you need? Many people have developed
educational materials to teach JESS, others have done consulting for
developing systems with JESS, yet others have created educational software
with JESS?
Thanks!
David

Well, first of all, do realize that floating point number
representations are finite and therefore inexact. 0.4 decimal is an

Again, 0.8 can't be precisely represented as a floating point number.

Ernest,
It is often helpful to have the parser spit out the column number of the
line with a parse error.
A while back I modified jess to track and display (on a parse error) the
current column number during parsing but lost the mods. I can reimplement
the changes using the current code base - ju
Hello everybody, If I have a particular fact in the knowledge base is it ok if I insert the same fact into the Knowledge Base sometime later without checking if that fact already exists, I know this wont make a difference but is it to do so. Is there any facility in JESS to know if a particular
I found that the following doesn't work:
(defclass Thing com.xxx.Thing) ; the class Thing has a property called
"name" of type String
(definstance Thing (new com.xxx.Thing))

=>
(printout t "Thing named Zaphod found")
)

LHS matching is done "as if by" the (eq) and (neq) functions. These do
no conversions at all, and so values match in content and type.
Conversion of function arguments is at the
18 matches
