The notion of generic ontologies is characterized through the formalization of ontological commitments and choices. Ontology repositories are used to modularize ontologies so that any […]

T. Hahmann, B. Brodaric, M. Gruninger: Voids and material constitution across physical granularities. Proc. of the 8th Int. Conference on Formal Ontology in Information Systems (FOIS-2014), 2014. IOS Press. Abstract: The relation between an object and its matter is fundamental to all physical sciences, and represented widely and diversely in scientific ontologies. An under-appreciated aspect of this relation is […]

T. Hahmann, B. Brodaric, M. Gruninger: Interdependence among material objects and voids. Proc. of the 8th Int. Conference on Formal Ontology in Information Systems (FOIS-2014), 2014. IOS Press. Abstract: Material-spatial interdependence (mat-dep) is a type of dependence in which the physical extents of two entities are necessarily and mutually contingent, e.g. an object and its matter, or a […]

B. Brodaric, T. Hahmann: Towards a Foundational Hydro Ontology for Water Data Interoperability. Proc. of the 11th Int. Conference on Hydroinformatics (HIC-2014). Abstract: Hydro ontologies are digital artifacts that contain representations of hydrological entities. They are being constructed to advance interoperability within and between all kinds of water data networks. Increased growth of such networks, however, requires integration of […]

Published: Jul 12, 2012 Author(s): Brodaric, Boyan, Hahmann, Torsten Abstract: Voids are extremely important to water science, because their size and connectivity determines the storage and flow of water both above and below the ground surface. While previous formal theories about voids strictly consider holes hosted inside objects, we generalize voids to also include spaces between objects, and distinguish voids in macroscopic […]

Joshua A. Lewis, Max J. Egenhofer. Oriented Regions for Linearly Conceptualized Features. Geographic Information Science, Lecture Notes in Computer Science Volume 8728, 2014, pp 333-348. Abstract: The typical phenomena in geographic space are 2-dimensional or 3-dimensional in nature, yet people often conceptualize some of them as 1-dimensional entities embedded in a 2-dimensional space—rivers have widths and depths, and […]

Egenhofer, Karine Ferreira, Pedro Andrade, Gilberto Queiroz, Alber Sanchez, Jim Jones, Lubia Vinhas. Fields as a Generic Data Type for Big Spatial Data. Geographic Information Science, Lecture Notes in Computer Science Volume 8728, 2014, pp 159-172. Abstract: This paper defines the Field data type for big spatial data. Most big spatial data sets provide […]
