Graph Analytics Using ArcGIS Knowledge

[#1]

This two-day course introduces foundational concepts, terminology, and workflows to perform graph analysis using ArcGIS Knowledge. Learn how to visualize and analyze spatial, nonspatial, structured, and unstructured data together in a knowledge graph, and build skills to combine graph analysis with spatial analysis to uncover relationships and hidden patterns in large amounts of data.

Lesson 1: Introducing ArcGIS Knowledge

• ArcGIS Knowledge product page
• Pro help documentation:
  • What is a link chart?  Get started with ArcGIS Knowledge
  • Explore an investigation and its knowledge graph
  • Essential ArcGIS Knowledge vocabulary

  • Graph Databases for Beginners: Graph Theory & Predictive Modeling by Neo4j blog

Lesson 2: Modeling data

• What is data modeling? (IBM)
• Arrows.app
• Graph Data Science Use Cases: Entity Resolution

Lesson 3: Preparing data

• ArcGIS Pro:
  • Data Engineering – Prepare Data
  • Alter Field (Data Management) - a use case for this tool: when using the Load Table Wizard, if a field contains the text "name" in it and is used as a property, that field name becomes the Display Name for that entity or relationship in the investigation view. Otherwise, you can not fully control what the Display Name is.
  • Calculate Field (Data Management)
  • Find and Replace (Edit tabular data)
  • Edit feature attributes (Attribute pane)
  • ArcGIS Interoperability
  • ArcGIS LocateXT
  • Text Analysis toolset in ArcGIS Pro’s GeoAI toolset
• Videos & Blogs:
  • Advanced Analytics Using Knowledge Graphs (UC 2023) 
  • Text Analysis using Natural Language Processing (NLP) in ArcGIS Pro 3.0 
  • Deep Learning Libraries Installers for ArcGIS (GitHub) 
  • Use the Named Entity Recognition model 
  • Extract Entities Using Deep Learning (GeoAI)

Lesson 4: Loading data

• ArcGIS API for Python:
  • Introduction to Knowledge Graphs
  • Edit Knowledge Graphs
  • arcgis.graph module
  • Create and load knowledge graph backups
• ArcGIS Pro:
  • ArcGIS Data Interoperability extension 
  • Load data into a knowledge graph
  • Create an investigation in a project (be sure to refresh if collaborating on the knowledge graph)
  • Add documents to a knowledge graph
  • Introduction to Data Engineering
  • Explore a knowledge graph with histograms
  • Add provenance to a knowledge graph

Lesson 5: Managing data

• Edit a knowledge graph in a link chart
• Merge entities and relationships

Lesson 6: Performing graph analysis
