This invention describes a computer system that takes an initial search request and some related ideas, which are specifically derived from a structured network of concepts. It then uses this information to formulate a more precise second search request, which is sent to another software component to retrieve information. The core of the invention relies on obtaining these related ideas from a specific type of concept map called a "directed minimum spanning tree."
Why it matters: Filed before the widespread adoption of advanced AI and large language models. The complex graph-based concept extraction and query refinement described could now be significantly enhanced or even automated by modern NLP techniques and LLMs, making the system more dynamic and less reliant on pre-built static graphs.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
