| Abstract: | |
| Ontological approach to solving tasks with the use of heterogeneous information sources implies reconcilability of ontological contexts of information source’s and task’s subject domains. On basis of relationships between reconciled ontologies, the problem of semantic relevance of task and source object schema specifications may be solved. The paper gives ground for the model of relating of information source object schemata to ontological specifications and considers which kinds of relationships may be derived from relationships in ontological information. There are different kinds of relations of ontological level taken to consideration: synonym, hypernym/hyponym, attributes, associations, part/whole, value contextualization functions. |
