  1. Individuals, Universals, Collections: On the Foundational Relations of Ontology.Thomas Bittner, Maureen Donnelly & Barry Smith - 2004 - In Achille Varzi Laure Vieu (ed.), Formal Ontology in Information Systems. Proceedings of the Third International Conference. IOS Press. pp. 37–48.
    This paper provides an axiomatic formalization of a theory of foundational relations between three categories of entities: individuals, universals, and collections. We deal with a variety of relations between entities in these categories, including the is-a relation among universals and the part-of relation among individuals as well as cross-category relations such as instance-of, member-of, and partition-of. We show that an adequate understanding of the formal properties of such relations – in particular their behavior with respect to time – is critical (...)

    Directly Depicting Granular Ontologies.Thomas Bittner, Maureen B. Donnelly & Barry Smith - manuscript
    (Published in an extended form as https://philpapers.org/rec/BITEAP) -/- We propose an ontological theory that is powerful enough to describe both complex spatio-temporal processes and the enduring entities that participate in such processes. For this purpose we distinguish between ontologies and metaontology. Ontologies are based on very simple directly depicting languages and fall into two major categories: ontologies of type SPAN and ontologies of type SNAP. These represent two complementary perspectives on reality and result in distinct though compatible systems of categories. (...)

  3. Granular Spatio-Temporal Ontologies.Thomas Bittner & Barry Smith - 2003 - AAAI Symposium:12-17.
    We propose an ontological theory that is powerful enough to describe both complex spatio-temporal processes (occurrents) and the enduring entities (continuants) that participate therein. The theory is divided into two major categories of sub-theories: (sub-) theories of type SPAN and (sub-)theories of type SNAP. These theories represent two complementary perspectives on reality and result in distinct though compatible systems of categories. In SNAP we have enduring entities such as substances, qualities, roles, functions; in SPAN we have perduring entities such as (...)

  4. Normalizing Medical Ontologies Using Basic Formal Ontology.Thomas Bittner & Barry Smith - 2004 - In K. Versorgung & V. Forschung (eds.), Ubiquitäre Information (Proceedings of GMDS 2004). Videel OHG. pp. 199-201.
    Description Logics are nowadays widely accepted as formalisms which provide reasoning facilities which allow us to discover inconsistencies in ontologies in an automatic fashion. Where ontologies are developed in modular fashion, they allow changes in one module to propogated through the system of ontologies automatically in a way which helps to maintain consistency and stability. For this feature to be utilized effectively, however, requires that domain ontologies be represented in a normalized form.

    Vague Reference and Approximating Judgements.Thomas Bittner & Barry Smith - 2003 - Spatial Cognition and Computation 3 (2):137–156.
    We propose a new account of vagueness and approximation in terms of the theory of granular partitions. We distinguish different kinds of crisp and non-crisp granular partitions and we describe the relations between them, concentrating especially on spatial examples. We describe the practice whereby subjects use regular grid-like reference partitions as a means for tempering the vagueness of their judgments, and we demonstrate how the theory of reference partitions can yield a natural account of this practice, which is referred to (...)

    Granular Partitions and Vagueness.Thomas Bittner & Barry Smith - 2003 - In Chris Welty & Barry Smith (eds.), Formal Ontology in Information Systems (FOIS). New York, USA: ACM Press. pp. 309-320.
    There are some who defend a view of vagueness according to which there are intrinsically vague objects or attributes in reality. Here, in contrast, we defend a view of vagueness as a semantic property of names and predicates. All entities are crisp, on this view, but there are, for each vague name, multiple portions of reality that are equally good candidates for being its referent, and, for each vague predicate, multiple classes of objects that are equally good candidates for being (...)

    A Spatio-Temporal Ontology for Geographic Information Integration.Thomas Bittner & Barry Smith - 2009 - International Journal for Geographical Information Science 23 (6):765-798.
    This paper presents an axiomatic formalization of a theory of top-level relations between three categories of entities: individuals, universals, and collections. We deal with a variety of relations between entities in these categories, including the sub-universal relation among universals and the parthood relation among individuals, as well as cross-categorial relations such as instantiation and membership. We show that an adequate understanding of the formal properties of such relations – in particular their behavior with respect to time – is critical for (...)
