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.
