The PW has one modification w.r.t. the original one, which is the subquantities: it has been moved to the parthood branch and refined into 6 sub-properties. Details are described in
Keet, C.M. Relating some stuff to other stuff. (submitted to an international conference)
OWLized version of the taxonomy of part-whole relations. Details are described in the paper:
Keet, C.M. and Artale, A. Representing and Reasoning over a Taxonomy of Part-Whole Relations. Applied Ontology, 2008, 3(1-2): 91-110.
This owl version is redone w.r.t. pwrelations, in that a DOLCEmini was imported and the pw taxonomy relations' domains and ranges now thus have a DOLCE IRI. Further, the whole-part inverses were added, and the respective proper parthood ones, and all those transitive ones explicitly asserted as transitive.
some object is constituted of some amount of matter.
example: a vase is constituted of clay
this portion *is* a portion of a larger amount of stuff. (cf. scattered portion)
examples: the bottom-half for the milk in the milk carton, the left quarter of the whole cake
superseded by stuff-part (for 'ingredient' stuffs) and portion (for parts of the same type of stuff)
parthood between processes.
example: swallowing is involved in eating
this portion *was* a portion of a larger amount of stuff; it needs a container. (cf. self-contained portion)
example: the wine in the wine glass is a scattered portion of the total amount that was in the wine bottle
this portion *was* a portion of a larger amount of stuff; it is a self-standing piece (e.g., a lump, drop, slide). (cf. contiguous portion)
example: the slice of the cake was part of the cake
The whole is generally denoted with a collective noun, i.e. a social object like Herd or Orchestra. The part is a physical entity or the role it plays, such as Sheep and Musician, respectively.
note: if you don't know which 'direction' to chose for an "all-some" construction for classes: in most cases, the hasPart direction is probably the right one; e.g., each human has part some heart, but not that each heart is part of some human (as there are other animals that also have a heart)
part-whole taxonomy of Keet and Artale (see Applied ontology 2008 for details). in short: it separates the 'true' mereological parthood from the meronymy-only ones. the former is transitive, the is either non-transitive or intransitive. this can also be seen from the respective domain and range axioms (with classes from the DOLCE foundational ontology)
parthood in mereology. only transitivity is asserted, not the rest, due to expressivity limitations
also called a noun-feature/activity, which relates an endurant to the process it participates in.
example: an enzyme that participates in a catalytic reaction, a runner participates in a marathon
relation between amounts of matter or stuffs (like gold, milk, mayonnaise), i.e., those entities that are in natural langauge indicated with mass nouns and are not countable, or only countable in amounts of the stuff.
this one is specific for a stuff and a portion that is of the *same* type of stuff. (cf. stuff-part)
examples: slice of the cake is a portion of the cake, glass of wine is a portion of the bottle of wine, etc.
usual proper parthood in mereology
structural parthood between two endurants
example: roof is part of a house
this portion *was* a portion of a larger amount of stuff. (cf. contiguous portion)
example: the wine in the wine glass is a scattered portion of the total amount that was in the wine bottle, the slice of the cake was part of the cake
relation between amounts of matter or stuffs (like gold, milk, mayonnaise), i.e., those entities that are in natural langauge indicated with mass nouns and are not countable, or only countable in amounts of the stuff.
this one is specific for a stuff and its 'ingredient' that is of *another* type of stuff. (cf. portions)
examples: alcohol is a stuff-part of wine, oil in mayonnaise, sugar in cake etc.
covers both portions and ingredients. to be refined.
examples: slice of the cake is a subquantity of cake, upper half of the milk in the milk carton, but also the alcohol as subquantity of wine, seasalt in the seawater.
superseded by stuff-part (for 'ingredient' stuffs) and portion (for parts of the same type of stuff)
see the respective inverses for annotations. the whole-part taxonomy is the 'mirror' of the part-whole taxonomy of Keet and Artale (see Applied ontology 2008 paper)
