Pushing the Boundaries of Tractable Multiperspective Reasoning: A Deduction Calculus for Standpoint EL+
Lucía Gómez Álvarez, Sebastian Rudolph, Hannes Strass
Standpoint EL is a multi-modal extension of the popular description logic EL that allows for the integrated representation of domain knowledge relative to diverse standpoints or pe…
Tractable Diversity: Scalable Multiperspective Ontology Management via Standpoint EL
Lucía Gómez Álvarez, Sebastian Rudolph, Hannes Strass
The tractability of the lightweight description logic EL has allowed for the construction of large and widely used ontologies that support semantic interoperability. However, compr…
How to Agree to Disagree: Managing Ontological Perspectives using Standpoint Logic
Lucía Gómez Álvarez, Sebastian Rudolph, Hannes Strass
The importance of taking individual, potentially conflicting perspectives into account when dealing with knowledge has been widely recognised. Many existing ontology management app…
AGM Belief Revision, Semantically
Faiq Miftakhul Falakh, Sebastian Rudolph, Kai Sauerwald
We establish a generic, model-theoretic characterization of belief revision operators implementing the paradigm of minimal change according to the seminal work by Alchourrón, Gärde…
A General Katsuno-Mendelzon-Style Characterization of AGM Belief Base Revision for Arbitrary Monotonic Logics
Faiq Miftakhul Falakh, Sebastian Rudolph, Kai Sauerwald
The AGM postulates by Alchourrón, Gärdenfors, and Makinson continue to represent a cornerstone in research related to belief change. We generalize the approach of Katsuno and Mende…
Knowledge Graphs Evolution and Preservation -- A Technical Report from ISWS 2019
Nacira Abbas, Kholoud Alghamdi, Mortaza Alinam +71
One of the grand challenges discussed during the Dagstuhl Seminar "Knowledge Graphs: New Directions for Knowledge Representation on the Semantic Web" and described in its report is…
On the Ontological Modeling of Trees
David Carral, Pascal Hitzler, Hilmar Lapp +1
Trees -- i.e., the type of data structure known under this name -- are central to many aspects of knowledge organization. We investigate some central design choices concerning the…
Worst-case Optimal Query Answering for Greedy Sets of Existential Rules and Their Subclasses
Sebastian Rudolph, Michaël Thomazo, Jean-François Baget +1
The need for an ontological layer on top of data, associated with advanced reasoning mechanisms able to exploit the semantics encoded in ontologies, has been acknowledged both in t…
Modeling in OWL 2 without Restrictions
Michael Schneider, Sebastian Rudolph, Geoff Sutcliffe
The Semantic Web ontology language OWL 2 DL comes with a variety of language features that enable sophisticated and practically useful modeling. However, the use of these features…
