Abstract

The analysis of formal-logical approaches to representation and interpretation of data and knowledge about oil-and-gas objects in the form of functionality exploration for frame-based, semantic-based and production-based representation forms is done. The production rule structure is presented in form that allows using AND, OR – operators, and with certainty factors as descriptions means for rule behavior modeling. The condition for production rules forming routine based on objects, comparators, domains, attributes and optional values is defined. It is shown, that introducing domain hierarchies for oil-and-gas related domain allows structuring and conceptualization of logical inferences accordingly to introduced goals ordering set. The structure of numerical, logical and categorical attributes is proposed, that allows the system to generate the sequences of questions in dialog form. The domains implementation is featured for subject area based on peculiarities of logical inferences, ordering rules and specification rules. The semantic presentations for related domain objects is constructed, by the means of defining corresponding semantic relations between objects and attributes, objects and rules, attributes and values, rules and domains. The implementation expediency for hybrid approach for oil-and-gas related-domain in the form of selected structural elements and theirs compositions is grounded.
