Earth to Major Tom Barry Smith
2 Earth = GIS Human Body = AIS
Two sides to SDTS Quantitative: Spatial Object Definitions (Raster/Vector...) Qualitative: Standard Entities
4 SDTS Spatial Object Definitions – 0-, 1-, 2-dimensions – elemental and aggregates – some examples from SDTS Node: topological junction of two or more links or chains, or is at an end point of link or chain Chain: nonbranching sequence on non-intersecting line segments or arcs, bounded by nodes at each end
5 Conceptual Level Standard Entities –Watercourse: a way or course through which water may or does flow (includes stream, river, anabranch, barranca, branch, brook, canal, channel, creek, culvert, ditch, drain, flume, fork, lode, narrows,... wash) Standard Attributes –Intermittent/Perennial: occurring in interrupted sequence vs. present at all seasons of the year
GIS strong on quantitative side, weak on qualitative side No robust geospatial ontology = no theoretically grounded taxonomy of the types of entities and relations in the geospatial world

Digital Anatomist Foundational Model of Anatomy (Department of Biological Structure, University of Washington, Seattle)
Goal in Biomedical Informatics use the methodology of formally defined relations and a common top-level ontology to bridge the granularity gap between genomics and proteomics data and phenotype (clinical, pharmacological, patient centered) data From molecules to diseases

We can reason across such hierarchies and combinations but only if the top-level categories and associated formal-ontological relations are well-defined and used consistently
Formal-Ontological Categories object process site layer fragment quality function relation boundary region
Formal-Ontological Relations is_identical_to is_a part_of develops_ from derives_ from located_at depends_on is_boundary_of has_participant has_agent adjacent_to contained_in precedes is_functioning_of has_function intends
To support integration of ontologies relational expressions such as is_a part_of... should be used in the same way by all the ontologies to be integrated
to define these relations properly we need to take account of both universals and instances in reality
A is_a B = def. ‘A’ is more specific in meaning than ‘B’
unicorn is_a one-horned mammal alien implant removal is_a surgical process Chios energy healing is_a therapeutic process
This linguistic reading yields a more or less coherent reading of relations like: ‘is_a’ ‘synonymous_with’ ‘associated_to’
but it fails miserably when it comes to relations of other types part_of = def. composes, with one or more other physical units, some larger whole contains =def. is the receptacle for fluids or other substances.
for how can concepts, on the linguistic reading, figure as relata of relations like: part_of adjacent_to connected_to
connected_to =def. Directly attached to another physical unit as tendons are connected to muscles. How can a meaning or concept be directly attached to another physical unit as tendons are connected to muscles ?
is_a human is_a mammal all instances of the universal human are as a matter of necessity instances of the universal mammal
Evaluation Good ontologies are those whose general terms correspond to universals in reality, and thereby also to corresponding instances in reality.
Kinds of relations : is_a, part_of,... : this explosion instance_of the universal explosion : Mary’s heart part_of Mary
Instance-level relations part_of is_located_at has_participant has_agent earlier...
part_of For instances: part_of = instance-level parthood (for example between Mary and her heart) For universals: A part_of B =def. given any instance a of A there is some instance b of B such that a part_of b
Different scientific cultures/terminologies immunology genetics cell biology
But: each (clinical, pathological, genetic, proteomic, pharmacological …) information system uses its own classification system How can we overcome the incompatibilities which become apparent when data from distinct sources is combined?
Answer: “Ontology”
Virtual Soldier Project Major Tom
Virtual Soldier Project Anatomy Reference Ontology = theoretical framework surrounding the Digital Anatomist Foundational Model of Anatomy
Virtual Soldier Project: Reference Ontology of Anatomy Reference Ontology of Physiology Reference Ontology of Disease Pathways
The Anatomy Reference Ontology is organized in a graph-theoretical structure involving two sorts of links or edges: is-a (= is a subtype of ) (pleural sac is-a serous sac) part-of (cervical vertebra part-of vertebral column)
Parthood vs. Location a part_of b = a located_in b OR a contained_in b

To define bio-ontological relations we need to take into account both components and processes (= continuants and occurrents) Components are that which changes; they are the bearers of processes. cell participates_in cell division
