System of collective construction of ontology with extended language of representation

The paper describes the concept of implementing of a system EZOP for the collaborative construction of ontologies. The main problem in the formalization of knowledge of groups of researchers in the form of ontologies is the need to study the language of representation of ontology. One of the most significant features of the system described in this report is the ability to extend the language by which users interact with the system. The approach described in the report allows experts to create own knowledge of language of representation that reflects their knowledge.
