Hello M-L,
=20
The following survey will give you a lot of more relevant references:
http://www.w3.org/2001/sw/BestPractices/RDFTM/survey
=20
About your last question(s)=20
1) you wrote: I know we can define semantic relationships between
topics/resources with TMs(or RDF).
But as a user, I cannot realize the significant differences between the
websites
have been built with TMs(or RDF) and those have not.=20
The website that is TM based will likely be more flexible because it is
easier to navigate in multiple directions and to navigate over relations
with different labels. The visualisation aspect of the resources with =
TMs
will also likely be more complete. See for instance the Vizigator at =
Ontopia
or
http://crewman-3.ivs.tu-berlin.de/PhotoGraph/index.html.
=20
I have been working in a project called I-MASS. In this project we =
worked
with RDF and in the end of the project we had to visualise concepts in =
the
information sources of libraries and museums. A lot of work and effort =
has
been put in resolving problems that you have with RDF (for instance:
identifying the concepts and blank nodes). In I-MASS we used the
CIDOC-Conceptual Reference Model just like in the project NZETC and I am
sure that if we had used Topic Maps in the project a lot of things would
have been a lot easier. Not so strange either because a lot of ideas of
Topic Maps are based from Library Science work.
=20
Of course it is possible that as a navigating user you won't notice
differences but the developer behind the scenes will notice them.
2) you wrote:=20
I cannot perceive their "power" of knowledge representation or =
knowledge
organization
because we can also represent semantic relationships without using =
TMs(or
RDF).
( I did not mean to offend anyone.)
=20
Yes you represent semantic relationships without TM or RDF BUT most of =
them
are not standardised or are about identity. The power of knowledge
representation is that is easier getting the right concepts you are =
talking
about or that you are looking for. If you represented them correctly it =
also
easier to find them. Problems with 2 concepts that have the same name =
are
for instance resolved. With knowledge representation techniques you can =
make
rules for identity and you make life easier when you need to integrate
information and applications.=20
3) you wrote:=20
Could anyone tell me what's the advantage for a website(or digital =
library,
portal...)
building with TMs(or RDF) ? (especially the advantage which couldn't be
accomplished
without TMs [or RDF] )
=20
If you build you website in the traditional way you need to a lot of =
things
yourself. With TM and RDF the structure will drive the presentation.
Maintaining content is a lot easier with TMs. And with TM you can =
connect
portals more dynamically then with traditional approaches. This is also =
one
of the reasons why publishers are following the TM activities quite =
well.
=20
There is a lot too say more to answer your questions but I hope this =
helps a
bit.

Hello everyone:
I know maybe I'm asking stupid questions, but I really need your help.
I was trying to find some websites help me recognize the ability of RDF =
and
TMs
on seamless knowledge [1] , Semantic Web, knowledge representation,=20
knowledge organization or information retrieval.
I noticed that there are some websites based on Topic Maps organizing
the resources, such as "Omnigator" [2] and "NZETC" [3] .
Are there any websites based on RDF organizing the resources too?
Any digital libraries or portals?
Another question. Are there any "web search engines" making for
searching Topic Map documents? (In addition to KartOO [4])
Such as "Swoogle" [5] search RDF documents.
Any websites you're impressed on implementing this two technologies are
appreciated.
The last question is:
I know we can define semantic relationships between topics/resources =
with
TMs(or RDF).
But as a user, I cannot realize the significant differences between the
websites
have been built with TMs(or RDF) and those have not.=20
I cannot perceive their "power" of knowledge representation or =
knowledge
organization
because we can also represent semantic relationships without using =
TMs(or
RDF).
( I did not mean to offend anyone.)
Could anyone tell me what's the advantage for a website(or digital =
library,
portal...)
building with TMs(or RDF) ? (especially the advantage which couldn't be
accomplished
without TMs [or RDF] )
Thanks in advance and best regards,
M-L.
