IDENTITY MANAGEMENT/ ENTITY RESOLUTION
Graph algorithms and graph embeddings are used for generating
context and resolving identities/entities
Neo4j APOC
Capture relationships between
entities across data sources
using a knowledge graph
Create additional
weighted relationships
based on similar text
description and/or other
similar metadata
Construct node
embeddings and
resolve entities based
on weighted pairwise
similarity between
various entities
Identify communities
of entities based on
distance between
node embeddings
