This database was created for purposes of the paper  "Learning missing edges via kernels in partially-known graphs", Senka Krivić, Sandor Szedmak, Hanchen Xiong, Justus Piater, European Symposium on Artificial Neural Networks, Computational Intelligence and Machine Learning 2015. Please cite this paper if you are using this database.

Database is generated based on the Princeton Shape Benchmark database "The Princeton shape benchmark", P. Min P.Shilane, M. Kazhdan, and T. Funkhouser, In Shape Modeling International, June 2004.

Database contains 4 datasets for each possible connection between objects (in, on, below and next to). 
Links between object are determined by values:
0 - no connection
1 - direct connection
-1 - reverse connection
empty- unknown connection
