arXiv:2607.01584v1 Announce Type: new Abstract: Large language models have recently been explored for scientific hypothesis generation, but most prior work relies on unstructured literature and free-form textual claims. We present a pipeline for Earth observation that grounds hypothesis generation directly in the NASA Earth Observation Knowledge Graph. A heterogeneous graph neural network trained on historical co-usage relations ranks candidate dataset pairings, and a three-agent LLM pipeline filters, generates, and evaluates structured research hypotheses. Applied to 1,475 NASA datasets, the
The proliferation of advanced LLMs and specialized knowledge graphs is enabling more sophisticated applications in scientific research, moving beyond unstructured data analysis.
This development allows for automated, data-driven hypothesis generation in Earth Observation, accelerating scientific discovery and potentially informing critical policy decisions.
The ability to generate structured, evaluated research hypotheses directly from expert knowledge graphs using generative AI transforms how scientific research questions are formulated, reducing manual effort and bias.
