Taxonomy

These are pairwise organism overlaps composed through the ubergraph hub, so each carries two materialized counts rather than one. exact_id = taxa with the identical NCBITaxon id on both sides (symmetric). clade_a_in_b / clade_b_in_a = how many of the first / second KG's taxa fall under the other's once expanded through ubergraph's subClassOf* hierarchy (directional). Clade membership is the more complete biological overlap and is often far larger when one KG records coarser taxa (genus) and the other finer ones (strain). Rows marked are label-bridged (biohealth, which carries no NCBITaxon ids, matched by exact scientific name) — see the note below the table. Like every other domain, Examples carries two questions per row: the count question (what the exact_id / clade columns measure) and the science question the pair answers.

KGsexact_idclade A-in-B / B-in-AExamples
biobricks-aopwiki × gene-expression-atlas-okn78 / 8How many organisms do biobricks-aopwiki and gene-expression-atlas-okn share? exact_id=7 carry the identical NCBITaxon id; clade membership (8 / 8) expands through the ubergraph hierarchy.

gene-expression-atlas-okn × sawgraph08 / 0How many organisms do gene-expression-atlas-okn and sawgraph share? exact_id=0 carry the identical NCBITaxon id; clade membership (8 / 0) expands through the ubergraph hierarchy.

Do the species SAWGraph samples for environmental contamination overlap the species Expression Atlas profiles? (exact_id = 0 - no species is directly shared; the overlap appears only under clade expansion, so treat this pair as a clade-level, not species-level, link.)
gene-expression-atlas-okn × spoke-genelab88 / 8How many organisms do gene-expression-atlas-okn and spoke-genelab share? exact_id=8 carry the identical NCBITaxon id; clade membership (8 / 8) expands through the ubergraph hierarchy.

For an organism in a NIAID Data Ecosystem dataset, what does spoke-okn know about the same species (its genes, proteins and disease associations)? Note the large clade asymmetry: spoke-okn's taxonomy is far broader, so clade expansion pulls in 33,601 spoke-okn taxa.

For a model organism used in a NASA GeneLab spaceflight experiment, what biomedical context does spoke-okn attach to the same species? Only 2 taxa match by exact id, but clade expansion through ubergraph reaches 33,313 spoke-okn taxa - so ALWAYS expand the clade here; an exact-id join badly understates this pair.
biohealth × biobricks-aopwiki †112 / 166How many organisms do biohealth and biobricks-aopwiki share by name? biohealth is label-bridged (no NCBITaxon ids), so 112 of biobricks-aopwiki's 166 NCBITaxon organisms match a biohealth concept by exact scientific name (approximate lower bound; no clade expansion).

Which organisms named in biohealth's UMLS health concepts have an Adverse Outcome Pathway declared applicable to them? biohealth carries NO NCBITaxon ids, so this is an approximate scientific-name match - a lower bound, and not safe for exact-id reasoning.
biohealth × gene-expression-atlas-okn †6 / 8How many organisms do biohealth and gene-expression-atlas-okn share by name? biohealth is label-bridged (no NCBITaxon ids), so 6 of gene-expression-atlas-okn's 8 NCBITaxon organisms match a biohealth concept by exact scientific name (approximate lower bound; no clade expansion).

For the organisms biohealth names as UMLS health concepts, does Expression Atlas profile expression in the same species? Name-bridged (no NCBITaxon ids on biohealth) - treat as an approximate lower bound.
biohealth × nde †1,052 / 1,808How many organisms do biohealth and nde share by name? biohealth is label-bridged (no NCBITaxon ids), so 1052 of nde's 1808 NCBITaxon organisms match a biohealth concept by exact scientific name (approximate lower bound; no clade expansion).

Which organisms biohealth names as UMLS health concepts also appear in NIAID Data Ecosystem datasets - e.g. a named pathogen concept with real underlying data? Name-bridged, so this 1,052-organism overlap is an approximate lower bound.
biohealth × sawgraph †377 / 538How many organisms do biohealth and sawgraph share by name? biohealth is label-bridged (no NCBITaxon ids), so 377 of sawgraph's 538 NCBITaxon organisms match a biohealth concept by exact scientific name (approximate lower bound; no clade expansion).

Which organisms biohealth names as UMLS health concepts are also sampled by SAWGraph for environmental contamination - linking a health concept to measured exposure in the same species? Name-bridged, so approximate.
biohealth × spoke-genelab †7 / 9How many organisms do biohealth and spoke-genelab share by name? biohealth is label-bridged (no NCBITaxon ids), so 7 of spoke-genelab's 9 NCBITaxon organisms match a biohealth concept by exact scientific name (approximate lower bound; no clade expansion).

Do NASA GeneLab's spaceflight model organisms appear as organism concepts in biohealth's UMLS-keyed health graph? Name-bridged (biohealth has no NCBITaxon ids) - an approximate lower bound.
biohealth × spoke-okn †1,603 / 34,570How many organisms do biohealth and spoke-okn share by name? biohealth is label-bridged (no NCBITaxon ids), so 1603 of spoke-okn's 34570 NCBITaxon organisms match a biohealth concept by exact scientific name (approximate lower bound; no clade expansion).

For an organism biohealth names as a UMLS health concept, what does spoke-okn record about the same species? The largest label-bridged overlap (1,603 of spoke-okn's 34,570 taxa match by scientific name) - but name-matched, so verify before asserting identity.

Label-bridged. biohealth carries no NCBITaxon ids, so these overlaps are matched by exact scientific name, not NCBITaxon id. For these rows the count is label_match / partner's total taxa — how many of the partner KG's NCBITaxon organisms have a same-name biohealth concept, out of that KG's total — and the exact_id/clade semantics of the other rows do not apply. Name-based and conservative (misses synonyms and spelling variants), with no subClassOf* clade expansion.
