FIELD: physics.
SUBSTANCE: method of extracting information from texts in the natural language comprises: receiving a text in a natural language using the processing device; executing syntactic and semantic analysis of a text in the natural language to obtain a plurality of semantic structures, interpretation of many of the semantic structures through a set of production rules to obtain a plurality of the data elements, each of which binds an attribute value with an information object that represents the entity, determining at least one data element in the set of the data elements of the confidence level by calculating a function of confidence represented by a linear classifier associated with the set of the production rules.
EFFECT: improving the accuracy of information to be extracted.
