How was the existing data linked to ontologies?
The GOA annotations link PubMed articles to GO concepts. Similarly, the PubMed data stores mappings to MeSH subject headings. In order to connect articles to FMA concepts, we mapped MeSH anatomical terms to FMA based on UMLS. This missed some key FMA-to-MeSH mappings (such as hippocampus). We used MMTx-from-NLM to augment the mappings, picking mappings with a perfect score.
