Automated novel concept extraction in natural language processing

This invention describes a computer method to identify novel ideas within a piece of text. It works by first extracting key ideas from a document. These ideas are then used to create a search query, which is run against a large collection of other texts. The system then extracts ideas from those search results. Finally, it compares the original ideas to the ideas found in the search results to determine how unique or 'external' the original ideas are. The claims specify that these key ideas can be simple keywords or keywords with their surrounding context.

Why it matters: Filed before advanced large language models were widely available. These models can now significantly simplify the concept analysis and query generation steps, making the core NLP tasks much more feasible.
