  • Method and system for machine-based extraction and interpretation of textual information
    Patent number: 9846692
    Abstract: A method and system of machine-based extraction of information from a text document employ the steps of performing semantic/syntactic analysis for sentences of the document to build semantic-syntactic structures of the sentences; applying production rules to the semantic-syntactic structures to generate a set of logical conclusions about objects of information comprised in the document, wherein the production rules are based on linguistic characteristics and lexical-morphological properties of the semantic-syntactic structures and ontologies of subject matters of the sentences; and using the set of logical conclusions about objects of information comprised in the document to build an ontology-based RDF graph.
