Uses open ministry data from 2011–2019 to build a temporal, tripartite knowledge graph of researchers–projects–subareas, integrating >45,000 researchers, ~15,000 projects and 7.5M+ collaboration links where collaboration = shared project. ETL disambiguates names by comparing local network neighborhoods. Database is Neo4j, natural language layer uses LangChain with local models and Gemini Pro/Flash to generate Cypher and summaries. Prototype UI supports Spanish queries and plans to add embeddings for semantic search.
