An ontological approach to the geological and economic assessment of the results of geological exploration as part of the information system of subsurface management
Abstract. The ontological approach is the development of a thesaurus of the subject area, the structure and composition of the knowledge base used in the process of geological and economic evaluation of the results of geological exploration. The relevance of this approach is not only in the content of the thesaurus and knowledge base, but also in the search for patterns and rules implicitly defining the functional subsystem of the object of study in the process of modeling the structure and links as part of the ontological model. The latter in this case is a set of geological exploration works aimed at prospecting, exploration, and evaluation of the subsurface. The subject of the study is the construction of an ontological model as a knowledge base of the subject area of geological and economic assessment, which is an element of the information system of subsurface management. The purpose of this work is to apply an ontological approach to the geological and economic assessment of the results of geological exploration as part of the information system of subsurface management. To achieve this goal, it will be necessary to solve the following tasks: to determine the functional scope of ontological modeling to evaluate the results of geological exploration, to determine the composition of the thesaurus of the subject area, to build an ontograph of the subject area, to determine the relationship of elements in practice. As a result, a system of geological and economic indicators was developed, which in the future can be integrated into the information system of subsurface management.
Keywords: ontological modeling, cost estimation, geological and economic monitoring, geological exploration, mineral resource complex
Highlights:
♦ the economic assessment of the results of geological exploration, taking into account their features, should be based on a knowledge base containing a thesaurus of geological and economic indicators for the stages of the geological exploration process;
♦ the connection of geological and economic indicators as part of the thesaurus of the ontological model of the subject area allows you to perform factor economic analysis;
♦ the actual assessment of the indicators as part of the thesaurus of geological and economic evaluation of the results of geological exploration allows us to characterize the condition of the research object and proceed to the calculation of the volume of output of mining commodity products, based on the condition of meeting the needs of a separate territory, region, state (taking into account the volume of exports and imports) in mineral raw materials.
