A Journey into Ontology Approximation: From Non-Horn to Horn [article]

Anneke Haga, Carsten Lutz, Johannes Marti, Frank Wolter
2020 arXiv   pre-print
We study complete approximations of an ontology formulated in a non-Horn description logic (DL) such as ALC in a Horn DL such as EL.  ...  We also define a notion of approximation tailored towards ontology-mediated querying, connect it to subsumption-based approximations, and identify a case where finite approximations are guaranteed to exist  ...  A journey into ontology approximation: From Non-Horn to Horn.

On the insufficiency of ontologies: problems in knowledge sharing and alternative solutions

Flavio S. Correa da Silva, Wamberto W. Vasconcelos, David S. Robertson, Virginia Brilhante, Ana C.V. de Melo, Marcelo Finger, Jaume Agustı́
2002 Knowledge-Based Systems  
In this paper we explore a number of realistic knowledge-sharing situations and their related problems for which ontologies fall short in providing a solution.  ...  One of the bene®ts of formally represented knowledge lies in its potential to be shared. Ontologies have been proposed as the ultimate solution to problems in knowledge sharing.  ...  For instance, the KIF expression , (a) (b and c) translates to the equivalent set of Horn clauses {a à b^c; b à a; c à a}: The bad news is that not all KIF expressions are translated into an elegant computational  ...

Out of Practice: Foreign Travel as the Productive Disruption of Embodied Knowledge Schemes

Christopher A. Howard
2015 The Indo-Pacific Journal of Phenomenology  
In a home world, cultural patterns offer actors "trustworthy recipes for interpreting the social world" (Schütz, 1944, pp. 501-502) that allow everyday experience to go largely unnoticed and unquestioned  ...  Using Husserlian and Heideggerian notions of "light breaks" and Dewey's theory of challenge, the author argues that foreign travel generates a form of embodied learning.  ...  Acknowledgement The author would like to thank the anonymous IPJP reviewers for their close reading of and insightful comments on an earlier draft of this paper.
