Automation of the conversion of natural language to formalized node of knowledge record

The paper describes the improvement of the system for automatic question answering based on the knowledge expressed in natural language sentences. The system is implemented using a relational database. This system will be the basis for the development of a web application for obtaining answers to the posed questions. In order for natural language sentences to be entered into a relational database, they must be prepared and formally recorded. The development of a question-answering system is based on the application of the conceptual framework Node of Knowledge (NOK), whose formalized record is suitable for input to a relational database from which answers to questions can be obtained. This paper presents an application for automated conversion of English sentences into a formalized record. The application was tested on one hundred simple English sentences, and the results of the automated conversion were compared with those obtained by processing the same sentences manually.
