Exploring Knowledge

How to find and navigate concepts in your knowledge graph.

Overview

After ingesting documents, you have a graph of interconnected concepts. Exploring means: - Searching - Finding concepts by meaning - Navigating - Following relationships between concepts - Connecting - Discovering paths between ideas - Verifying - Tracing concepts back to sources

Search finds concepts by meaning, not just keywords.

CLI

kg search "climate change effects"

Returns concepts semantically similar to your query, even if they use different words.

With options: 

# Limit results
kg search --limit 20 "economic policy"

# Filter by ontology
kg search --ontology "research" "neural networks"

# Show more detail
kg search --verbose "machine learning"

Web Interface

  1. Use the search bar at the top
  2. Results show concepts ranked by similarity
  3. Click any concept to see details

Understanding Results

Each result shows: - Concept name - The extracted idea - Similarity score - How close to your query (0-1) - Grounding - How well-supported (-1 to +1) - Source count - How many documents mention it

Viewing Concept Details

CLI

kg search details <concept-id>

Shows: - Full concept information - All evidence (source text that led to this concept) - Relationships to other concepts - Grounding breakdown

Web Interface

Click any concept to open its detail view: - Evidence panel - Original text excerpts - Relationships panel - Connected concepts - Sources panel - Documents where it appears

Concepts connect to other concepts. Explore these connections:

kg search related <concept-id>

Returns concepts directly connected, grouped by relationship type: - Supports - Contradicts - Implies - Causes - Part of

Filter by Relationship Type

kg search related <concept-id> --type SUPPORTS
kg search related <concept-id> --type CONTRADICTS

Explore Deeper

# Go 2 hops out
kg search related <concept-id> --depth 2

# Go 3 hops
kg search related <concept-id> --depth 3

More hops = more concepts, but further from the original.

Finding Connections

Discover how two concepts relate:

CLI

kg search connect "concept A" "concept B"

Finds paths between concepts, showing how ideas chain together.

Options: 

# Limit path length
kg search connect "X" "Y" --max-hops 3

# Use concept IDs for precision
kg search connect abc123 def456

What Paths Show

A path might look like: 

Climate Change
  ──[CAUSES]──> Sea Level Rise
  ──[AFFECTS]──> Coastal Cities
  ──[IMPLIES]──> Migration Patterns

This reveals the chain of reasoning connecting distant ideas.

Exploring Contradictions

Find where sources disagree:

Search for Contested Concepts

kg search "vaccination effects"

Look for concepts with mixed grounding (scores near 0) in the results.

View Both Sides

When you find a contested concept: 

kg search details <concept-id>

The evidence section shows which sources support and which contradict.

Filter by Epistemic Status

kg vocabulary list --status CONTESTED

Shows relationship types that have mixed evidence across the graph.

Exploring by Source

Start from a document and see what was extracted:

List Sources in an Ontology

kg ontology files <ontology-name>

View Document's Concepts

In the web interface: 1. Navigate to Documents 2. Select a document 3. See all concepts extracted from it

Visual Exploration (Web)

The web interface provides visual navigation:

Graph View

  • Concepts as nodes
  • Relationships as edges
  • Click to focus
  • Drag to rearrange
  • Zoom to explore

Filters

  • By ontology
  • By grounding threshold
  • By relationship type
  • By date range

Highlighting

  • Hover to see connections
  • Click to lock focus
  • Double-click to expand neighborhood

Exploration Strategies

Start Broad, Narrow Down

  1. Search for a general topic
  2. Find a relevant concept
  3. Explore its relationships
  4. Follow promising connections

Follow Contradictions

  1. Look for low-grounding concepts
  2. Check which sources disagree
  3. Understand both perspectives
  4. Form your own view

Map a Topic

  1. Search for the central concept
  2. Get all related concepts (depth 2-3)
  3. Look for clusters and bridges
  4. Identify key relationships

Verify Claims

  1. Find the concept
  2. Check its grounding score
  3. Read the source evidence
  4. Trace to original documents

Tips

Use Specific Queries

"Effects of sleep deprivation on memory" finds more relevant concepts than "sleep".

Check Grounding Before Trusting

High grounding (> 0.7) means many sources agree. Low or negative means contested or contradicted.

Explore Neighborhoods

The most interesting insights often come from concepts 2-3 hops away from your starting point.

Compare Ontologies

If you have separate knowledge bases, search both to see how different document sets treat the same topics.
