The pipeline is configured as an end-to-end neural Open Schema Construction pipeline having a coreference resolution module, an open information extraction (OIE) module, and an entity canonicalization module. The processed textual data is input to a graph database to create the knowledge graph displayable through a graphical user interface. In operation, the pipeline modules serve to create a single term for all entity mentions in the corpus that reference the same entity through coreference resolution, extract all subject-predicate-object triplets from the coreference resolved corpus through OIE, and then canonicalize the corpus by clustering each entity mention to a canonical form for mapping to the knowledge graph and display."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Autonomous open schema construction from unstructured text","description":"Disclosed is a natural language processing pipeline that analyzes and processes a corpus of textual data to automatically create a knowledge graph containing the corpus entities such as subjects and o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11977569","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
