Retrofitting Distributional Embeddings to Knowledge Graphswith Functional Relations
Table 3: Retrofitting to SNOMED-CT. Reported values are mean and standard deviation of the link prediction accuracies over three experiments. The number of edges used for (training/testing) is shown below each edge type.
['[BOLD] Retrofitting Model', '[BOLD] ‘Has Finding Site’', '[BOLD] ‘Has Pathological Process’', '[BOLD] ‘Due to’', '[BOLD] ‘Cause of’']
As the SNOMED-CT ontology is dominated by synonymy-like relations, we expect the simple retrofitting methods to perform well. Our implementation supports the use of different function classes to represent different relation types; in practice, we recommend that users select function classes in accordance with relation semantics.
