#Allegheny_River__Allegheny  a river that rises in Pennsylvania and flows north into New York and then back south through Pennsylvania again to join the Monongahela River at Pittsburgh which is the beginning of the Ohio River
  part of:  New_York_State  Pennsylvania
  supertype:  river  a large natural stream of water (larger than a creek); "the river was navigable for 50 miles"
     supertype:  stream__watercourse  a natural body of running water flowing on or under the earth
        supertype:  body_of_water__water  the part of the earth's surface covered with water (such as a river or lake or ocean); "they invaded our territorial waters"; "they were sitting by the water's edge"
           supertype:  physical_object__object  a tangible and visible entity; an entity that can cast a shadow; "it was full of rackets, balls and other objects"
              supertype:  non-agentive_physical_object__NAPO  e.g., a bottle
                 supertype:  physical_object__POB

                          supertype:  spatial_object__spatialobject  object which as a direct spatial location, e.g., physical object, spatial region or shape
                             supertype:  object__entity_with_spatial_feature  spatial object (space, location or physical object) or description medium/container (e.g., string, language, image); in a 4D ontology, an object is something whose spatiotemporal extent is thought of as dividing into spatial parts roughly parallel to the time-axis
                                supertype:  entity  something that can be "involved" in a situation
                                   supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
                                supertype:  physical__physical_thing  an entity that has a location in space-time; locations are themselves understood to have a location in space-time; click here for more details on the identical category sowa#physical_thing
                                   supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
                             supertype:  partially_tangible__partiallytangible  A subcollection of cyc#SpatialThing-Localized and cyc#TemporalThing. Each instance of cyc#PartiallyTangible has a tangible (i.e. material) part and a temporal extent (i.e. it exists in time). It might or might not also have an intangible part. For example, a particular copy of a book is made of matter, has temporal extent, and also has an intangible part: the information content of the text markings on its pages.
                                supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
                             supertype:  individual__particular___supertype_of_1st_order_types  all individuals (for concepts or relations) are implicitely or explicitely instance of that type
                                supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
                          supertype:  endurant__ED
                             supertype:  entity  something that can be "involved" in a situation
                             supertype:  thing  an object seen from a 3D (or endurantist) perspective, i.e. where a spatial entity may have a time independent identity, as opposed for example to the 4D perspective where each spatial entity has an associated time frame; click here and here for details
                                supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
                             supertype:  endurant_or_perdurant__ED_or_PD
                                supertype:  quality_or_endurant_or_perdurant__Q_or_ED_or_PD
                                   supertype:  entity  a category from DOLCE or generalized by a category from DOLCE
                                      supertype:  individual__particular___supertype_of_1st_order_types  all individuals (for concepts or relations) are implicitely or explicitely instance of that type

                       supertype:  tangible  Something which is not intangible, something which is physical, made of matter. It does not matter whether things are real of imaginary. Therefore we consider Mickey Mouse's car and a hippogriff as  tangible things
                          supertype:  temporal_thing  The collection of all things that have temporal extent or location, i.e. things about which one might sensibly ask When? . cyc#TemporalThing thus contains many kinds of things, including events, physical objects, agreements, and abstract pieces of time. Note that cyc#TimePoint is a specialization of cyc#TemporalThing, since time points have temporal location, although they arguably lack temporal extent. Abstract things that are timeless -- such as mathematical sets, attributes, and numbers -- are of course _not_ instances of cyc#TemporalThing.
                             supertype:  thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
