Small is Again Beautiful in Description Logics
Veranstaltungsart:
Kolloquium Angewandte Informatik
Description Logics (DLs) are a popular family of logic-based
knowledge representation languages, which have been used
in various application domains such as natural language
processing, databases, configuration of technical systems,
biomedical ontologies, and the Semantic Web. The Description
Logic (DL) research of the last 20 years was mainly concerned
with increasing the expressive power of the employed
description language without losing the ability of implementing
highly-optimized reasoning systems that behave well in practice,
in spite of the ever increasing worst-case complexity of the underlying
inference problems.
OWL DL, the standard ontology language for the Semantic Web, is
based on such an expressive DL for which reasoning is highly
intractable. Its sublanguage OWL Lite was intended to provide a
tractable version of OWL, but turned out to be only of a slightly
lower worst-case complexity than OWL DL. This and other reasons
have led to the development of two new families of light-weight DLs,
EL and DL-Lite, which recently have been accepted as profiles of
OWL 2, the next version of the OWL standard. In this talk, I
will give an introduction to these new families of logics and explain
the rationales underlying their design.
