Fusions of Description Logics and Abstract Description Systems
Fusions are a simple way of combining logics. For normal modal logics, fusions have been investigated in detail. In particular, it is known that, under certain conditions, decidability transfers from the component logics to their fusion. Though description logics are closely related to modal logics, they are not necessarily normal. In addition, ABox reasoning in description logics is not covere...
متن کامل8 Description Logics Systems
This chapter discusses implemented description logic systems that have played or play an important role in the field. It first presents several earlier systems that, although not based on description logics, have provided important ideas. These systems include Kl-One, Krypton, Nikl, and Kandor. Then, successor systems are described by classifying them along the characteristics discussed in the ...

KR: knowledge representation. DLs: Description Logics; a family of logic-based KR languages for representing knowledge through assertions about concepts, individuals and relationships among them. (Logic-based) Semantics: a way to interpret any statement in a language; logic-based semantics interprets such a statement using operations in mathematical logic. Interpretation: a mathematical structu...
متن کاملConnecting Abstract Description Systems
Combining knowledge representation and reasoning formalisms like description logics (DLs), temporal logics, and logics of space, is worthwhile but difficult. It is worthwhile because usually realistic application domains comprise various aspects of the world, thus requiring suitable combinations of formalisms modeling each of these aspects. It is difficult because the computational behavior of ...
متن کاملFusions of Description
1 Motivation and outline In order to ensure a reasonable and predictable behaviour of a Description Logic (DL) system, reasoning in the DL employed by the system should at least be decidable, and preferably of low complexity. Consequently, the expressive power of the DL in question must be restricted in an appropriate way. If the imposed restrictions are too severe, however, then the important ...
