Tutorial 2023/08/22: How to determine if two entities are truly the same?

[matentzn]

When SSSOM was originally introduced, the hope was that if you just give people a standard model for mapping metadata, they would magically produce better mappings. 2 years and many litres of tears later, it is clear that there is not even a remotely shared understanding of what it means for two entities (terms, classes, codes, etc) to be "the same".

I would like to try to provide you with a general mental framework for determining "sameness" for your own use cases, and "curation rules" that allow use to clearly document the assumptions by which a "sameness" decision was made.

Concretely, my hope is to help people become more confident about the distinctions of "exact", "broad", "narrow", "close" and "related" matches (see https://mapping-commons.github.io/sssom/mapping-predicates/) when they determine a mapping, and more explicit in documenting the rules by which they arrive at a decision.

This would be extremely helpful for my work and I would love to be able to link to this Tutorial in the context of the NFDI working group ontology harmonization and mapping.
