Database technology is constantly evolving not only toward more efficient data management techniques but also toward more expressive conceptual models. In particular, Object-Oriented databases have evolved to the point that the expressive gap with respect to knowledge representation systems has been filled. In the paper, we present the Object-Oriented data language OOL with the intention of assessing its adequacy in supporting AI applications. To this end we compare OOL with FL, a typical knowledge representation language designed for AI applications. The comparison is carried out along two lines: the expressive power and the computational complexity of subsumption. The results show that the Object-Oriented data language OOL can be considered a first class citizen among the Frame Definition Languages.

Abstract
Database technology is constantly evolving not only toward more efficient data management techniques but also toward more expressive conceptual models. In particular, Object-Oriented databases have evolved to the point that the expressive gap with respect to knowledge representation systems has been filled. In the paper, we present the Object-Oriented data language OOL with the intention of assessing its adequacy in supporting AI applications. To this end we compare OOL with FL, a typical knowledge representation language designed for AI applications. The comparison is carried out along two lines: the expressive power and the computational complexity of subsumption. The results show that the Object-Oriented data language OOL can be considered a first class citizen among the Frame Definition Languages.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
