I have used the Jena API to deal with Ontologies created by Protege before. Jena is, admittedly confusing. However, these are resources that I used to help figure it out.
SWOOP is pretty outdated, if you're going to use a GUI, I recommend you stick with Protoge 4. For information on using Pellet, there's a pretty good tutorial online.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
