Essay

This dissertation addresses a research and practical objective: extracting knowledge from specialized domain texts for use in professional practice. The aim is to provide rapid access to structured knowledge and enable automated text analysis through the development of ontology engineering methods and an ontology-based knowledge extraction information technology. The proposed ontology-based knowledge extraction technology integrates developed methods for identifying key concepts, detecting relations between them, and classifying concepts based on fuzzy logic criteria to enhance the functionality of the knowledge extraction process. This integrated approach enables the holistic analysis, formalization, and subsequent utilization of knowledge from specialized texts, accounting for their linguistic and domain-specific features, for use in expert systems, information services, and educational platforms. Experiments conducted on a corpus of criminal law texts confirmed the effectiveness and acceptable accuracy of the proposed ontology-based information technology for the formal representation of documents. The proposed technology can subsequently be utilized for rapid retrieval of relevant information and the discovery of latent dependencies within specialized text corpora.
