Algebra of matching ontology contexts in conditions of incomplete information

Abstract

Algebra for ontology manipulation, needed for formalization of matching operations and elements search in taxonomy hierarchies, represented by various data sources is suggested in the paper. The need of the developed algebra is motivated by inability of global consistent ontology achievement, that is why it is proposed to match on local level for topically related sources. Possible fields of application are information articles evaluation and their attainability optimization in hypertext systems.
