The technology for ontology instance data authoring

Ontologies and semantic web technologies are the leading means for knowledge-base development nowadays. The article suggests the classifiers and matrix language for ontology instance data authoring together with corresponding software. The language and tool allow users to visualize hierarchical relationships between ontology individuals, to distinguish instance types using icons and to represent links between elements from hierarchical list using matrix. The article also maps the suggested language to web ontology language (OWL), provides mechanism for knowledge-base editor interface design, lists implementation examples and makes evaluation of the suggested technology.
