[Swoop] Re: swoop

Sat Oct 23 23:03:31 EDT 2004

thx  for the quick response.  i got 2.2 beta2 (oct 8th 04) from your 
downloads page - http://www.mindswap.org/2004/SWOOP/downloads/
that was the most recent one listed.  ( i did not get the "nightly 
build" since i did not know if that would be useful for an outsider and 
someone naive enough not to know what build directly from SVN means...)

one comment inline below.

by the way, i am a java novice - didnt even have it on my machine at 
home prior to this aft and i do not seem to have all the right things in 
my path but i just gave the command line an explicit path to find the 
java.exe and then started swoop right up.  (i used your error statement 
to know that i had to have ....java -cp lib\swoop.jar 
org.mindswap.swoop.Swoop as the command.
i didnt read any documentation or watch any movies (they did not come up 
on my machine) and i basically put the ontology in about as fast as i 
could click and type.
i did not have to  look for commands - they seemed to be where i 
expected them.
that is probably a pretty good statement in terms of usability.

the one thing i tried to find but did not find was a way to see the 
ontology from just the told information (not once pellet had done its 
reasoning.  i thought maybe if i chose rdfs rather than pellet that i 
would not see the result of the equivalences but this was not the case).

maybe it does in your newer version but in mine - show inherited is 
checked and i do not see it.

i tried deleting the domain of location and then adding the domain of 
emergency situation and that worked  but that is not what needs to be 
modeled.
(yes - i know they are equivalent  but this is a philosophical modeling 
question as well....)
