Efficient Visualization of Knowledge Graphs Based on Next-Generation Language Models

The results show that the proposed methodology is not limited to a single algorithm and permits the combination of direct extraction, specialized models, multi-stage pipelines, and OWL ontologies, which can be applied to the analysis of scientific, technical, and regulatory texts in a secure local environment.
