Integrace v systému VirGIS a na sémantickém webu
Linková, Zdeňka
Integration has been an acknowledged data processing problem for a long time. However, there is no universal tool for general data integration. Because various data descriptions, data heterogeneity, and machine unreadability, it is not easy way. Improvement in this situation could bring the Semantic Web. Its idea is based on machine understandable web data, which bring us an opportunity of better automated processing. The SemanticWeb is still a future vision, but there are already some features we can use. The paper describes how is integration solved in mediation integration system VirGIS and discusses use of nowadays Semantic Web features to improve it. According to the proposed changes, a new ontology that covers data used in VirGIS is presented.

Mohou kognitivní a inteligentní systémy překonat Turingovy stroje?
Wiedermann, Jiří
We look for computational limits of artificial, natural and hybrid cognitive and intelligent systems. The common basis for such studies is offered by computationalism, i.e., the belief that cognitive or intelligent processes, respectively, are in essence computational processes. We show that in principle cognitive systems might exist whose computational power outperforms that of Turing machines and that even in practice we observe the rudiments of such systems.

Unlimited Evolutionary Growth of the Computational Power of Self-Reproducing Automata and Other Results
Wiedermann, Jiří
We design two original computational models - viz. a globular universe and the autopoietic automata - capturing essential features of evolution: the construction of self-reproducing evolutionary automata via self-assembly and genetic information transfer from the parents to their offsprings. Within this framework we show the unlimited growth of the computational power of automata during their evolution and we characterize the power of lineages of such automata with the help of interactive Turing machines.
