The Development the Knowledge Base of the Question-Answer System Using the Syntagmatic Patterns Method

This paper presents an ontological model of a text document of a large electronic archive. In addition, the article contains original algorithms for extracting syntagmatic patterns from text documents. The paper also describes the developed search algorithms in the knowledge base of the electronic archive using the mechanism of syntagmatic patterns. In conclusion, the results of the experiments on the developed question-answer (QA) system in comparison with existing information systems are presented.
