For example, this ontology can be manipulated using directives such as: (1) set Crookston campus homeroom two Clark to sports football captain which are incrementally interpreted by transitioning down the subsumption lattice (e.g., from sports to football to captain) or forking to another part of the lattice (e.g., from Clark to sports).
as an ontology like this is navigated in spoken language, there is a sense in which other referents e at the same level of the ontology as the most recently described referent e, or at higher levels of the ontology than the most recently described entity, should be semantically accessible without restating the ontological context (the path from the root concept e ) shared by e and e. in the context of having recently referred to someone in Homeroom 2 at a particular campus in a school activities database, other students in the same homeroom or other activities at the same campus should be accessible without giving an explicit back up directive at each branch in the ontology.
