The granted patent US12008045B2 outlines a method and system for associating personally identifiable information (PII) with entities derived from multiple content objects. The core of the invention involves constructing an entity graph that includes nodes representing PII and corresponding entities. The method processes queries to identify direct and indirect associations between these nodes and content objects, utilizing scores to rank these associations. By traversing connections within the entity graph, the system can identify common PII nodes and formulate a result set that includes relevant information about the entities involved. Additionally, the method allows for the identification of identical entities by augmenting the graph with connections based on shared PII.

Further, the patent details the use of linguistic analysis and natural language processing to enhance the accuracy of entity identification. This includes decomposing passages to recognize grammatical structures that may indicate relationships between PII and entities. The system is designed to operate efficiently, requiring less memory for the entity graph compared to the original content objects. The patent also emphasizes compliance with PII detection rules and preferences, ensuring that the results produced by the system can be aligned with regulatory requirements. Overall, the invention provides a structured approach to managing and associating PII across diverse data sources, enhancing the ability to identify and connect entities accurately.
