Generating Hierarchical JSON Representations of Scientific Sentences Using LLMs
arXiv:2603.23532v1 Announce Type: new Abstract: This paper investigates whether structured representations can preserve the meaning of scientific sentences. To test this, a lightweight LLM is fine-tuned using a novel structural loss function to generate hierarchical JSON structures from sentences collected from scientific articles. These JSONs are then used by a generative model to reconstruct the original text. Comparing the original and reconstructed sentences using semantic and lexical similarity we show that hierarchical formats are capable of retaining information of scientific texts effectively.

Executive Summary
This study explores the efficacy of structured representations, specifically hierarchical JSON structures generated by Large Language Models (LLMs), in preserving the meaning of scientific sentences. By fine-tuning a lightweight LLM with a novel structural loss function, the researchers are able to generate hierarchical JSON representations from sentences collected from scientific articles. These representations are then used by a generative model to reconstruct the original text, demonstrating the ability of hierarchical formats to retain scientific text information effectively when compared to semantic and lexical similarity metrics.
