Jerry Zhu's excellent SSL Tutorial (covers non-graph SSL as well)
SSL Book edited by Olivier Chapelle, Bernhard Schölkopf, and Alexander Zien
This toolkit consists of implementations of various graph-based semi-supervised learning (SSL) algorithms. Currently, three algorithms are implemented: Gaussian Random Fields (GRF), Adsorption, and Modified Adsorption (MAD). Starting with v1.2.0, Junto also contains Hadoop-based implementations of these three algorithms.
