Solution Overview

Problem

The segregation of information across different spaces (public, semi-private, and private) leads to information overload and inefficiency in accessing relevant information, as existing methods are application-centric, domain-centric, or interest-centric, failing to establish meaningful connections and requiring manual integration of data from multiple sources.

Innovation Solution

A person-centric INDEX system that cross-links and organizes information from various spaces into a unified, dynamic space tailored to the individual, using entity extraction and disambiguation to provide intent-based information presentation and automated task completion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If information is organized in segregated spaces (public, semi-private, private) using conventional application-centric or domain-centric methods, then information can be stored and accessed within each space, but information overload occurs and meaningful connections between related information across spaces are lost

Engineering Contradiction:
Improveloss of meaningful connectionsVSAvoidcomplexity of information organization
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent merges information from multiple segregated spaces (public, semi-private, private) into a unified person-centric knowledge graph. This integration preserves meaningful connections between related information across different spaces by representing all entities and their relationships in a single connected structure, eliminating the information loss that occurs in segregated organization.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The knowledge graph serves as a universal structure that handles multiple functions: storing information from diverse sources, establishing semantic relationships, enabling entity disambiguation, and supporting various query types. This multi-functional approach reduces the need for separate systems for each function, simplifying the overall information organization complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If conventional application-centric or domain-centric methods are used to organize information, then each application or domain can manage its own information subset, but users must manually search and integrate information across multiple segregated spaces

Engineering Contradiction:
Improveease of information retrievalVSAvoidtime for manual information integration
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically extracting entities, determining entity types, identifying candidate entities, and establishing relationships between entities across different spaces before user queries. This pre-processing creates a ready-to-query knowledge graph structure, eliminating the need for users to manually search and integrate information across multiple spaces at query time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The knowledge graph system provides self-service by automatically organizing information from multiple spaces, resolving entity ambiguities, and establishing semantic relationships without user intervention. The system autonomously builds and maintains the connected information structure, freeing users from manual information integration tasks.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If entity names are extracted from data sources without disambiguation, then entity extraction is simple, but entity candidates cannot be accurately identified when multiple entities share the same name

Engineering Contradiction:
Improveprecision of entity identificationVSAvoidcomplexity of entity disambiguation process
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The entity disambiguation process is segmented into distinct stages: entity name extraction, entity type determination, candidate entity identification, and final entity selection. Each stage processes specific aspects of disambiguation using appropriate methods, making the overall complex process manageable and systematic while improving identification precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Entity type determination serves as an intermediary step between simple entity name extraction and final candidate identification. By introducing entity types as a mediating classification layer, the system narrows down candidate entities and improves identification precision without requiring direct complex disambiguation logic at each step.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present teaching relates to entity extraction and disambiguation. In one example, an entity name extracted from a data source associated with a user is obtained. One or more entity types associated with the entity name are determined. One or more entity candidates are identified with respect to each of the one or more entity types. An entity candidate is selected with respect to one of the one or more entity types to be an individual associated with the entity name.
