Structure preserving TBox repair using defaults


Scharrenbach, T; Grütter, R; Waldvogel, B; Bernstein, A (2010). Structure preserving TBox repair using defaults. In: 23rd International Workshop on Description Logics (DL 2010), Waterloo, Canada, 2010 - 2010, 384-395.

Abstract

Unsatisfiable concepts are a major cause for inconsistencies in Description Logics knowledge bases. Popular methods for repairing such concepts aim to remove or rewrite axioms to resolve the conflict by the original logics used. Under certain conditions, however, the structure and intention of the original axioms must be preserved in the knowledge base. This, in turn, requires changing the underlying logics for repair. In this paper, we show how Probabilistic Description Logics, a variant of Reiter’s default logics with Lehmann’s Lexicographical Entailment, can be used to resolve conflicts fully-automatically and receive a consistent knowledge base from which inferences can be drawn again.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
