Exploiting longer cycles for link prediction in signed networks

Kai-Yang Chiang, Nagarajan Natarajan, Ambuj Tewari, Inderjit S. Dhillon
2011 Proceedings of the 20th ACM international conference on Information and knowledge management - CIKM '11  
We consider the problem of link prediction in signed networks.  ...  We see that our supervised method not only achieves good accuracy for sign prediction but is also especially effective in lowering the false positive rate.  ...  In particular, signed link prediction has connections to social balance theory while no such connection exists for the standard (unsigned) link prediction task.  ...

Evaluating the Calibration of Knowledge Graph Embeddings for Trustworthy Link Prediction [article]

Tara Safavi, Danai Koutra, Edgar Meij
2020 arXiv   pre-print
We first conduct an evaluation under the standard closed-world assumption (CWA), in which predicted triples not already in the knowledge graph are considered false, and show that existing calibration techniques  ...  Next, we introduce the more realistic but challenging open-world assumption (OWA), in which unobserved predictions are not considered true or false until ground-truth labels are obtained.  ...  Table 3 also compares link prediction accuracy before and after calibration.  ...
