I think Wikipedia is a good site to learn stuff, provided that you check the sources. Most of the information on that site has to be sourced (you can check the source by click on the number superscript). But for something like research, I would only say Wikipedia be a guide to what your topic is about.
Anyhow, about the articles of Islamic philosophies, the general idea for each is correct, or atleast from what I learned in religions of the world.
