abstract = "Explainability is crucial to support the adoption of
machine learning as a tool for scientific discovery. In
the biomedical domain, ontologies and knowledge graphs
are a unique opportunity to explore domain knowledge,
but most knowledge graph-based approaches employ graph
embeddings, which are not explainable. However, when
the prediction target is finding a relation between two
entities represented in the graph, such as in the case
of protein-protein interaction prediction, semantic
similarity presents itself as a natural explanatory
mechanism. This work uses genetic programming over a
set of semantic similarity values, each describing a
semantic aspect represented in the knowledge graph, to
generate global and interpretable explanations for
protein-protein interaction prediction. Our experiments
reveal that genetic programming algorithms coupled with
semantic similarity produce global models relevant to
understanding the biological phenomena",
