Reasoning with Projection in Multimodular Description Logics Knowledge Bases,me non-interesting fragments). Projection is most useful for modular knowledge bases in which only parts of knowledge have to be exchanged or imported to other modules. In this paper we present an optimized method of reasoning over results of projection. The tests indicate that the method can drasti

Contextualizing a Knowledge Base by Approximation - A Case Study,organize a modular knowledge bases organized into contexts in which a user can express their knowledge in much simplified way, yet without losing its precision. The work is centered around the notion of approximation - i.e. reducing the arity of predicates used. The presentation is based on a case-s

An Ontology-Enabled Approach for Modelling Business Processes,ely studied and successfully applied in modelling of workflows and workflow systems. There is an inherent problem regarding business processes modelled with CPNs sharing and subsequently their reuse need to be considered. The Semantic Web technologies, such as ontologies, with their characteristics

Grouping Multiple RDF Graphs in the Collections,ne a lightweight representation of graphs which emphasizes legibility and brevity. We also present an implementation of our system, an algorithm of mapping to a pure RDF model and algorithms of generation and normalization. Our proposal supports knowledge metrics for RDF graphs.

Nondeterministic Decision Rules in Rule-Based Classifier, created as the result of shorting deterministic rules in accordance with the principle of minimum description length (MDL). As deterministic rules in database we treat the full objects description in a meaning of descriptors conjunction. The nondeterministic rules are calculated in polynomial time
