چکیده

The paper describes representation and use of variable and nontypical relations of concepts in the Sociopolitical thesaurus constructed specially as a tool for automatic text processing. The variable and non-typical conceptual relations are described in the simplest way by marking of relations by modifiers. The simplicity of notation facilitates representation of such relations for large number of concepts in the Sociopolitical thesaurus and allows to create multidimensional description of the thesaurus concepts.

For instance, in medical imaging, two images of the same anatomic part in a given modality have a very similar appearance. In the proposed approach, a conceptual indexing phase ext...
