Researchers have developed a novel method using graph neural networks (GNNs) to create hierarchy-aware embeddings for knowledge graphs. This approach incorporates semantic loss derived from ontologies to better represent domain knowledge. The method was applied to predict yeast phenotype, achieving a mean R^2 score of 0.360 for double gene knockouts, outperforming baseline models. Incorporating semantic loss further improved predictive performance to R^2=0.377, demonstrating the value of ontology structure for quantitative predictions and potentially guiding biological discovery.
