The field of vaccinology requires structured knowledge to ensure data interoperability. Manual updates to vaccine ontologies are tedious and often fail to keep pace with rapid scientific advancements. Consequently, researchers have developed vaccine ontology automation using the BERTopic pipeline. This semi-automated method extracts relevant concepts from the prestigious Plotkin's Vaccines corpus. Specifically, the workflow integrates advanced natural language processing tools like spaCy and lightweight transformer models.
Furthermore, the system utilizes UMAP for dimensionality reduction and HDBSCAN for clustering thematic topics. The pipeline then employs Keyword extraction (KeyBERT) and BART summarization to improve interpretability for clinical experts. In addition, the system incorporates seed words from existing ontologies to guide the discovery process toward medical relevance. Moreover, a tree-merging module unifies these hierarchies into a coherent representation similar to a formal ontology.
Subject Matter Experts (SMEs) subsequently review the results to filter irrelevant terms and map them to the Vaccine Ontology. Ultimately, this study demonstrates that automated approaches significantly reduce the labor required for manual database maintenance. The results showed coherent clusters representing immune mechanisms, pathogen-specific data, and various vaccine types. Therefore, clinicians can benefit from more accurate and structured medical databases for decision support.
Healthcare providers in India frequently rely on integrated data for public health policy and immunization strategies. Consequently, improving the speed of knowledge integration helps maintain the accuracy of digital health records. This scalable strategy ensures that vaccinology remains well-organized for future research and clinical applications.
BERTopic uses advanced machine learning to group related vaccine concepts, making it easier to organize large volumes of medical text into structured data for clinical use.
Subject Matter Experts review the automatically generated topics to filter out irrelevant terms and ensure the extracted data aligns perfectly with established medical frameworks.
