This invention describes a computer method for identifying specific names or entities (like people, places, or organizations) in text. It works in stages: first, it breaks down words to understand their basic forms and meanings, then uses this to make initial guesses about entities. If those initial guesses aren't good enough, or if a user requests it, the system performs a deeper analysis of sentence structure and meaning to refine its identification of entities.
Why it matters: Filed before large language models (LLMs) became prevalent. LLMs can now perform sophisticated named entity recognition and semantic analysis, potentially simplifying or enhancing the multi-stage process described, or even making parts of the original method less necessary for achieving similar results.
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.
