;; ================================================ ;; SUMO (Suggested Upper Merged Ontology) ;; ================================================ ;; This is the source file for the SUMO (Suggested Upper Merged Ontology), ;; an ontology that was developed within the SUO Working Group by merging ;; the SUO "candidate content" sources and refining and extending this content on ;; the basis of various knowledge engineering projects and input from the SUO ;; Working Group. ;; The SUMO incorporates elements of John Sowa's upper ontology (as described at ;; http://www.bestweb.net/~sowa/ontology/toplevel.htm and in Chapter 2 of his ;; book _Knowledge Representation_, Brooks/Cole, 2000), Russell and Norvig's ;; ontology, PSL (Process Specification Language), Casati and Varzi's theory of ;; holes, Allen's temporal axioms, the relatively noncontroversial elements of ;; Smith's and Guarino's respective mereotopologies, the KIF formalization of the ;; CPR (Core Plan Representation), the ontologies available on the Ontolingua ;; server maintained by Stanford University's Knowledge Systems Laboratory, the ;; ontologies developed by ITBM-CNR, some of the spatial relations from an ;; unpublished paper by Iris Tommelein and Anil Gupta entitled "Conceptual ;; Structures for Spatial Reasoning", and a "Structural Ontology" proposed by ;; David Whitten and substantially revised and extended by Chris Menzel. ;; Note that some of the subclasses of 'Process' in the SUMO were originally ;; inspired by some of the verb classes from the second part of Beth Levin's book ;; "English Verb Classes and Alternations: A Preliminary Investigation." ;; The knowledge representation language in which the SUMO is expressed is SUO-KIF, ;; which stands for "Standard Upper Ontology - Knowledge Interchange Format". SUO-KIF ;; is a simplified form of the popular KIF knowledge representation language. A ;; specification of SUO-KIF can be found at: http://suo.ieee.org/suo-kif.html. It ;; should be noted that some of the axioms in the SUMO make use of row variables ;; (indicated with a "@" prefix). Such variables are not currently part of the SUO- ;; KIF specification, but they simplify matters significantly in some cases. Details ;; about row variables can be found in the following paper: ;; http://reliant.teknowledge.com/IJCAI01/HayesMenzel-SKIF-IJCAI2001.pdf. ;; The SUMO is a modular ontology. That is, the ontology is divided into ;; self-contained subontologies. Each subontology is indicated by a section ;; header, and the dependencies between the subontologies are specified with ;; statements of the form ";; INCLUDES ''". These statements are ;; found at the beginning of each section. The dependencies between the ;; various subontologies can also be graphed informally as follows: ;; ;; STRUCTURAL ONTOLOGY ;; + ;; | ;; | ;; + ;; BASE ONTOLOGY ;; / | | \ ;; / | | \ ;; / | | \ ;; / | | \ ;; / | | \ ;; + + + + ;; SET/CLASS THEORY NUMERIC TEMPORAL MEREOTOPOLOGY ;; / | | | ;; / | | | ;; / | | | ;; + + + + ;; GRAPH MEASURE PROCESSES +--+ OBJECTS ;; + + ;; \ / ;; \ / ;; \ / ;; + + ;; QUALITIES ;; ;; ;; Note that the "+" sign at the end of an arc indicates the direction of ;; dependency - the node near the sign includes the subontology at the other ;; end of the arc. Note too that in some cases the dependency is ;; bidirectional. Separating ontologies in cases like these is useful when ;; their respective topics can be cleanly differentiated. ;; BEGIN FILE ;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;; STRUCTURAL ONTOLOGY ;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;; INCLUDES 'BASE ONTOLOGY' ;; The Structural Ontology consists of definitions of certain syntactic ;; abbreviations that can be both heuristically useful and computationally ;; advantageous.
