Semantic analysis-based query result retrieval for natural language procedural queries

This invention describes a system that answers natural language questions, especially those asking how to do something. It works by first converting your question into a structured format that captures the actions and relationships within it. Then, it takes potential answers, converts them into the same structured format, and compares how well they match your question's structure. The best matching answer is then provided. Specifically, the structured format involves breaking down both the question and answers into 'action, role, value' components, which are then compared using a set of rules.

Why it matters: Filed before the widespread adoption of powerful Large Language Models (LLMs), the core challenge of accurately converting natural language into structured semantic representations (like action-role-value triples) has become significantly more tractable and effective with modern LLM capabilities.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSoftware logic, natural language processing, semantic parsing
