From: A new synonym-substitution method to enrich the human phenotype ontology
Example of synonymy generated by our method. On the left side, a very small excerpt of the HPO hierarchy for hearing impairment (HP:0000365) is shown. On the middle side, for each HPO class, part of the current synonym set is shown. The lexical differences between some terms and its descendant terms are highlighted in color. Different lexical overlaps are underlined in different colors, only to make it easier to identify them in the figure. On the right side, some new synonyms generated by our method are displayed. The arrows show the origin of the new synonyms
