ontology-building
ResearchCampaign for building domain ontologies — systematic concept extraction, relation typing, taxonomy construction, and iterative refinement. Produces a structured concept hierarchy in the wiki vault.

Ontology Building
Build a structured ontology for a research domain. Extracts concepts from sources, types their relationships, constructs taxonomies, validates consistency, and iteratively refines until the ontology is coherent and complete.

Budget Table
| Metric | Small | Medium | Large |
|---|---|---|---|
| Source pages ingested | 10 | 25 | 50 |
| Concept pages created | 15 | 40 | 80 |
| Edges created | 30 | 100 | 200 |
| Taxonomy depth (levels) | 2 | 3 | 4 |
| Validation passes | 1 | 2 | 3 |
Strategy Sequence (Reference, Not Prescription)
- domain-scoping — define boundaries, identify seed concepts, classify topic size
- concept-extraction — mine sources for concepts, create pages, resolve aliases
- relation-typing — identify and type relationships between concepts
- taxonomy-validation — check hierarchy consistency, detect gaps and conflicts
- ontology-refinement — merge near-duplicates, fill gaps, update confidence scores
CC may reorder, skip, or repeat strategies based on the domain's needs.

Context-Management
Guiding Principles
- Breadth before depth. Map the concept landscape broadly before drilling into any sub-area.
- Edges over pages. A concept without relationships is useless. Prioritize connecting over creating.
- Aliases are enemies. The same concept with different names fragments the ontology. Resolve aggressively.
- Confidence is honest. Mark uncertain classifications explicitly. Low confidence is better than false certainty.
- The ontology is never finished. Each research session may reveal new concepts or invalidate old ones.
Available Strategies
Optional, no fixed order; the final leaf is always a sop.
| Strategy | When to use |
|---|---|
| concept-extraction | Strategy for mining concepts from sources — systematic extraction, page creation, alias resolution. |
| domain-scoping | Strategy for defining ontology boundaries — identify seed concepts, classify topic size, establish scope constraints. |
| ontology-refinement | Strategy for iterative ontology improvement — merge duplicates, fill gaps, update confidence, prune dead branches. |
| relation-typing | Strategy for identifying and typing relationships between concepts — create edges with appropriate types and weights. |
| taxonomy-validation | Strategy for validating ontology consistency — check hierarchy, detect cycles, verify completeness. |
Available Tactics
Optional, no fixed order; the final leaf is always a sop.
| Tactic | When to use |
|---|---|
| concept-decomposition | Tactic for breaking compound concepts into atomic parts — split over-broad concepts, identify sub-components, create child pages. |
| hierarchy-construction | Tactic for building is-a and part-of hierarchies — establish parent-child relationships, verify transitivity, detect cycles. |
| knowledge-compilation | Tactic for compiling research findings into vault pages — orchestrates page creation, updates, edge linking, and index maintenance. Minimum yield ≥3 page operations per invocation. |
| knowledge-structuring-consistency-checking | Tactic for verifying ontology consistency — detect contradictions, cycles, orphans, and type violations. |
Available SOPs
Optional, no fixed order; the final leaf is always a sop.
| SOP | When to use |
|---|---|
| context-checkpoint | Append research process and results to the current Phase's context file. Each append MUST contain >=500 lines of markdown covering both process and results. Use this skill at plan-designated checkpoint points — typically after each strategy completes or at key decision nodes within a research Phase. |
| context-init | Create a new context file for a research Phase. Called once at Phase start to initialize the file that subsequent context-checkpoint calls will append to. Use this skill whenever a new research Phase begins and a fresh context file is needed. |
