You can also look at the OGC SFS document #99-049 Here: http://www.opengeospatial.org/standards/sfs or here: http://www.loni.ucla.edu/twiki/pub/CCB/Meeting30March2005/99-049.pdf
Also, the JTS Javadoc has a lot of information on this, in the classes Geometry and IntersectionMatrix

Is there a graphic that shows the various possible intersection matrices that can be yielded from a "relate()" call? A link to the spec, a picture, and an accompanying table would be, to my lights, VERY useful additions to the standard docs. I realize that they are out there in cyberspace somewhere, but it is a pain in the neck to find them even with Google, and a summary graphic is all I really want. I would recommend an Appendix B in the main docs. I would offer to write this up, but I don't know much about it.
