发帖数: 3271 | 4 Conceptually, think about the domain of you application, i.e. what are the
basic action operators in your domain? what are the agent roles required by
applications, and what are the capabilities of each roles.
Technically, first you must decide how to do symbolic inference in you system.
This is the most important part.
All above have little to do with JADE.

why dont we learn it together here instead of ...?
I'd like to understand it well too. In today's talk, somebody talked
about ontology, but i'm still not very clear.
I found a link here for ontology:
http://www-ksl.stanford.edu/kst/what-is-an-ontology.html
It defines ontology as "a specification of a conceptualization", but it
is still too abstract :(
as i understand, ontologies are some rules, or constraints for some models.

发帖数: 3271 | 6 It's a good try but the big problem is that it's actually still a procedural
programming tool conceptually, only hidden under a declarative syntax. It's
like directly programming on SOAP, which is weird and counter productive.

发帖数: 3271 | 7 You said it:) Declarative and Procedural programming are conceptually very
different. When you use declarative syntax to express procedural concepts,
it's unnatural and problems may occurs. And why you want to do that in the
first place? Because it's XML? |

发帖数: 3271 | 9 There is a branch in AI called knowledge representation, which studies logic

In AI terms, query on Relational DBMS, is essentially a special case of

发帖数: 3271 | 10 I found it would be too expensive to discuss all those questions:))
But as to the performance issue, the key thing is, all relational operations can be implemented with same or better performance in OODB with proper storage / indexing strategy. In other words, conceptually RDBMS can be regarded as a special case of OODB. Downgrading an OODB to RDBMS is very easy, but upgrading a RDBMS to OODB would be difficult, requiring ugly patching such as ORM. That's why 10 years ago most people in universi |

the
pointers
It's quite the other way around IMO. The differences are more between the
concepts than the implementations. References (or "pointers in Java") are
largely still implemented as actual memory pointers, but conceptually a
reference does not point to a particular memory location, and that leads
to a couple of important distinctions:
1. you cannot offset a reference like you would a memory pointer, and
2. a reference references an object, so when the object moves, the reference

I found some benchmarks on a site which I can't seem to find
any more. Basically the takeaway point from those benchmarks
was that scala and java are pretty close for mostly procedural
code, but as soon as you get into functional programming,
scala's performance starts dropping.
That's not saying scala is an inefficient language. It's
just the fact well-known-for-four-decades that functional
programming provides convenience and conceptual simplicity
at the price of efficiency. |

发帖数: 685 | 21 void test::hello() is actually void hello(test*)
Since the hello function just prints without using the passed test* pointer,
nothing goes wrong. Conceptually
it is a class static member function.
If you make hello a virtual function, things will change - even the hello
function body does not explicitly need
a valid this pointer, the process locating the function needs a valid this
pointer so it basically will crash.
I suggest you always checking the assembly code when having any doubt about
C++ |

发帖数: 685 | 22 Hmmm initially I thought it was just a matter of wording. After a bit
googling I realized differentiating hide from override is conceptually more
correct - it better illustrates the distinction between compile-time or run-

So thanks for clearing an issue cheating me for so long time :-)
And hail to C++ since you keep knowing how poor your knowledge about it is
even if you code in it everyday - a sign you always are on learning curve :-

发帖数: 1340 | 33 in latex, it is conceptually natural to embed environments inside
others, but it always gives me a lot of troubles in doing so. for
example, "eqnarray*" can not be embeded in a tabular. my questions
are
1. is there any rule-of-thumb which determines which environment
can be nested in another one and which can't?
2. is there any trick to by-pass these constraints? for example, i
might really wish to nest some equations inside a tabular.
thanks! |

发帖数: 1340 | 34 thanks for the long reply, :).
personally, i think it would be great that all environments (or some

to implement. |

I would like to understand ontologies as generally an authoritative expression
of conceptual
relationships between a group of terms (entities) in a defined
area, such as ontoloties for a medical area, a branch of science etc.
XML is a tool to express ontologies. A variety of operations can be
applied to ontologies, e.g., modification and join with
each other etc.
Any comments?
