Toten Framework Outperforms Statistical Tokenization for Physical Quantities in Brazilian Portuguese Technical Texts
Researchers present Toten, a framework that replaces statistical tokenization with ontology-based classification for physical quantities and technical notation in Brazilian Portuguese. The system leverages external oracles and achieves higher ontological atomicity and numerical reconstruction compared to state-of-the-art baselines.

LLM Agent With Ontology Constraints Automates Standardization of Legacy Biomedical Metadata
Researchers have developed an LLM-based metadata standardization system that queries standard reporting guidelines and biomedical terminology services in real time. Tested on 839 legacy records from the Human BioMolecular Atlas Program, the approach consistently improves prediction accuracy over LLM-only methods for both ontology-constrained and non-ontology-constrained fields.
