Viime Extract is a web application for generating and curating knowledge graph data, focused on metabolomics and infectious disease use cases. Research papers and tabular data is fed into the system and analyzed with large language AI models (LLMs). The resultant JSON-LD data is matched against known ontologies (e.g. KEGG) and existing graph databases (e.g. Reactome). Extracted knowledge is also stored in a central graph database and presented to the user in an intuitive interactive visualization for validation and correction. In addition to providing a novel integrated, easy-to-use workflow, Viime Extract incorporates AI prompt and AI model selection tools to enable customization and optimization of automated results over time.
