# Gap Identification

Discover where gaps exist in the research landscape.

## When to Use

User has a research area and needs to find what's missing — uncharted territory, under-explored intersections, or absent evidence.

## Budget

| Base SOP | Target | ±10% Range |
|----------|--------|------------|
| web-search | 60 | 54–66 |
| web-research | 10 | 9–11 |
| paper-overview | 80 | 72–88 |
| paper-search | 30 | 27–33 |
| paper-research | 5 | 4–6 |

## State Ledger

Print before every iteration:

```
<HARD-GATE>
| SOP | Done | Target | % |
|-----|------|--------|---|
| web-search | ? | 60 | ? |
| web-research | ? | 10 | ? |
| paper-overview | ? | 80 | ? |
| paper-search | ? | 30 | ? |
| paper-research | ? | 5 | ? |
Budget Gate: OPEN/CLOSED (>=80% required to exit)
</HARD-GATE>
```

## Available Tactics

- evidence-mapping

## Available SOPs

**Import:** web-search, web-research, paper-overview, paper-search, paper-research
**Subagent:** gap-keyword-extraction, concept-matrix-construction, egm-construction

## Execution Guidance

Start with broad web-search + paper-overview to map the landscape. Use gap-keyword-extraction to identify gap-indicating sentences. Build concept-matrix to visualize coverage. Construct EGM for structural view of where evidence is dense vs absent.

## Output Format

Gap Candidate List with evidence pointers — each candidate includes: gap description, evidence source, confidence level, and location in concept matrix.

## Available Tactics

Optional, no fixed order; the final leaf is always a sop.

| Tactic | When to use |
| --- | --- |
| evidence-mapping | Systematic evidence map construction — search, classify, locate gaps, visualize. Combines concept-matrix-construction, gap-keyword-extraction, evidence-grading, and egm-construction SOPs. |

## Available SOPs

Optional, no fixed order; the final leaf is always a sop.

| SOP | When to use |
| --- | --- |
| concept-matrix-construction | Build articles × concepts coverage matrix to visualize research landscape and identify empty cells as gap candidates. |
| egm-construction | Build structured Evidence Gap Maps — define axes (intervention × outcome or method × domain), place gaps in cells, annotate with evidence density and quality. |
| gap-keyword-extraction | Extract gap-indicating sentences and phrases from papers/reviews. Identifies linguistic markers of research gaps (e.g., "remains unclear", "has not been explored", "limited understanding"). |
