At the moment, I was able to find these papers:
1. Prototype a Knowledge Discovery Infrastructure by Implementing Relational Grid Monitoring Architecture (R-GMA) on European Data Grid (EDG) by Frank Wang, Na Helian, Yike Guo, Steve Thompson, John Gordon.
2. Knowledge grid-based problem-solving platform by Lu Zhen, Zuhua Jiang,Jun Liang.
Thank you in advance for any help.
