Hi everybody,
thanks for all your kind answers in my last ("Auto-Generating TMs out of
rel. DB") thread. I was unable to check my e-mails for the last couple of
days and on top of that, they are on another computer, so iīll answer the
questions raised in my other thread about Auto-Generating TMīs out of
relational Databases in the next days (depending when i can access my other
computer). Sorry for that.
Now, as the other thread lost itīs way somehow and was skipping to the
aspect of the "Visualization Of Topic Maps", i wanted to open a thread where
we might gather information about different Visualiztation technics/APIs for
Topic Maps and so forth.
As this seems to be a topic, which not only I am really interested in.
Maybe we can also keep an eye on the usability of the generated graphs, when
handling large topic maps.
I will work with the Touchgraph and maybe Hypergraph renderes in the next
time and can write my opinions on this, when i have finished.
Open Source Visualizations i know of at the moment (keep in mind that iīm no
pro when it comes down to TMs, so this is just what i think of them, any
idea, criticism is highly appreciated):
--------------
Touch Graph:
--------------
http://touchgraph.sourceforge.net/
KNOWN IMPLEMENTATIONS: There are a number of different implementations
around (see link), i donīt know how far these are based onto Topic Maps.
For topic maps there is the Java Stand Alone Application TMNav
(http://tm4j.org/tmnav.html), which relies onto the TM4J framework
(http://tm4j.org/), which is providing an implementation of the TouchGraph
for browsing Topic Maps
DEVELOPMENT STATUS: It looks like the project is mostly dead, judging from
the last release on sourceforge from the end of 2002
POTENTIAL: imho itīs good at browsing TopicMaps as it is interactive. For a
bigger example of this one can have a look at the Google Browser implmeneted
with Touchgraph: http://www.touchgraph.com/TGGoogleBrowser.html, it has good
options to parameterize the graph in a way you want it to look
DOWNSIDE: Not really developed any further, donīt know how good it scales on
big graphs with lotīs of topics, looks like no good documentation is
available, development mostly based onto extracting the knowledge from the
source files
--------------
HyperGraph:
--------------
http://hypergraph.sourceforge.net/
KNOWN IMPLEMENTATIONS: There are a number of different implementations
around (see link), i donīt know how far these are based onto Topic Maps.
For topic maps there is the Java Stand Alone Application TMNav
(http://tm4j.org/tmnav.html), which relies onto the TM4J framework
(http://tm4j.org/), which is providing an implementation of the HyperGraph
for browsing Topic Maps
DEVELOPMENT STATUS: It looks like the project is still running, the last
release on sourceforge is from the end of 2004
POTENTIAL: good at browsing large TopicMaps, because of hyperbolic
visualization
DOWNSIDE: i donīt know how good you can parameterize the graph for your own
needs
--------------
Prefuse
--------------
http://prefuse.sourceforge.net/
KNOWN IMPLEMENTATIONS: A couple of implementations are on the website (see
link), i donīt know how far these are based onto Topic Maps.
DEVELOPMENT STATUS: The project is up and running, with the latest release
from April 2005
POTENTIAL: looks like lotīs of different visualization options are possible,
the project aim is to develop highly interactive visualisations. I donīt
know whether there is something similar to TouchGraph or HyperGraph already
out there.
DOWNSIDE: i donīt know how much programming effort it takes to visualize a
Topic Map in a similar vein TouchGraph or Hypergraph does

--------------
http://jung.sourceforge.net/
KNOWN IMPLEMENTATIONS: A couple of implementations are on the website (see
link), i donīt know how far these are based onto Topic Maps.
DEVELOPMENT STATUS: The project is up and running, with the latest release
from April 2005
POTENTIAL: looks like lotīs of different visualization options are possible,
i am not sure whether one can configure this visualisation to make it
"browsable" like HyperGraph or TouchGraph or whehter this is more or less
"static".
DOWNSIDE: i donīt know how much programming effort it takes to visualize a
Topic Map in a similar vein TouchGraph or Hypergraph does
Maybe you are interested to share your opinions on Graph visualization, or
know of further Visualization techics.
Iīd love to hear what you have to say about this topic.
Greetings
Andreas
