narrative-topology（叙事拓扑）

Narrative Topology

Core Concept

Problem: Long discussions (100+ messages, architectural debates, narrative analysis) lose structure. Easy to miss critical dependencies, causality chains, or bottlenecks.

Solution: Embed RDF-style triples in markdown. Scan with Python. Extract semantic adjacency matrix. See structure.

Triple Notation

Format

<<{Subject, Predicate, Object}.

Examples

Simple relations:

<<{Claude, outputs, analysis}.
<<{analysis, informs, decision}.

Parallel subjects (cartesian product):

<<{[A, B, C], implements, feature}.

Expands to:

{A, implements, feature}
{B, implements, feature}
{C, implements, feature}

Parallel objects:

<<{payment_system, affects, [latency, cost, security]}.

Expands to:

{payment_system, affects, latency}
{payment_system, affects, cost}
{payment_system, affects, security}

Both parallel:

<<{[Claude, User], collaborated_on, [design, implementation]}.

Full cartesian product: 2×2 = 4 edges.

Syntax Rules

• <<{ starts the triple
• }. (period-dot) terminates
• Commas separate subject, predicate, object
• Whitespace trimmed automatically
• [...] denotes list; bare tokens are singletons
• Lines in markdown, easily greppable

Why This Format

1. RDF-like — Semantic web standard, well-understood
2. Grep-friendly — grep '<<{' file.md finds all triples
3. Unambiguous — Clear start/end, no nesting
4. Markdown-native — Doesn't break rendering
5. Compact — One line per relation

Example: Hamlet

Input markdown (partial):

## Act I

<<{Claudius, murders, old_king}.
<<{Claudius, usurps, Denmark_throne}.
<<{Claudius, marries, Gertrude}.

## Act II

<<{ghost, reveals, Hamlet}.
<<{ghost, demands, revenge}.
<<{Hamlet, feigns, madness}.
<<{Hamlet, kills, Polonius}.

## Consequences

<<{Polonius_death, causes, Ophelia_madness}.
<<{Ophelia, drowns, river}.

## Climax

<<{[Hamlet, Laertes], duel, each_other}.
<<{[poison_sword, poison_wine], kills, [Hamlet, Laertes, Claudius, Gertrude]}.
<<{Fortinbras, takes_over, Denmark}.

Output: Adjacency matrix showing all 14 nodes and their causal/narrative dependencies.

Output

The scanner outputs an adjacency matrix compressed with x::n notation (n copies of value x):

Nodes: Claudius, Denmark_throne, Fortinbras, Gertrude, Hamlet, Laertes, Ophelia, Polonius, Polonius_death, ...

Adjacency Matrix (compressed x::n):
# x::n = n copies of value x
0::14
0::3,1::1,0::10
0::4,1::2,0::8
1::14
...

Stats:
Nodes: 14
Edges: 12
Density: 0.0612

Format rule: x::n means n consecutive occurrences of value x. Example: 0::2,1::3,0::1 expands to [0,0,1,1,1,0].

For AI analysis: The matrix rows = sources (in node list order), columns = targets. 1 = edge exists.

Interpreting the Matrix

Rows = Sources, Columns = Targets

Matrix M where M[i,j] = 1 means: Node_i → Node_j

Key Analyses

· In-degree (column sum): How many things cause this node? (Count 1s in each column) · Out-degree (row sum): How many things does this node cause? (Count 1s in each row) · Strongly connected components: Cycles (feedback loops, mutual causality) · Topological sort: Order events by causal dependency · Critical path: Chain with maximum bottleneck nodes

Extending the Scanner

Add Weighted Edges

Replace binary (0/1) with strength values:

# Instead of setting to 1, count occurrences
weight_matrix = [[0] * n for _ in range(n)]
for s, o in edges:
    i, j = idx[s], idx[o]
    weight_matrix[i][j] += 1

Output matrix has counts, not just binary.

Generate Mermaid Graph

Add to scanner:

print("graph LR")
for s, o in edges:
    print(f"  {s} --> {o}")

Pipe output to a .mmd file, render in claude.ai.

Generate GraphViz DOT

print("digraph {")
for s, o in edges:
    print(f'  "{s}" -> "{o}";')
print("}")

Render with dot, convert to PNG/SVG.

Use Cases

1. Narrative Analysis

Extract plot dependency from novel/screenplay. · Identify critical turning points (high in-degree) · Find orphaned subplots (isolated nodes) · Spot circular dependencies (tragedy, irony)

1. Architectural Discussions

Embed triples in design doc markdown:

   <<{microservice_A, calls, microservice_B}.
   <<{microservice_B, depends_on, database}.
   <<{database, shared_by, [service_C, service_D]}.

Scan → see service coupling graph → identify decoupling opportunities.

1. Project Workflows

Task dependencies:

   <<{design_doc, blocks, implementation}.
   <<{implementation, requires, code_review}.
   <<{code_review, unblocks, deployment}.

Scan → topological sort → critical path analysis.

1. Technical Debt Mapping

   <<{legacy_code, causes, technical_debt}.
   <<{technical_debt, blocks, new_feature}.
   <<{new_feature, required_by, [OKR_1, OKR_2]}.

Prioritize refactor based on downstream impact.

Integration with all-dialogue-to-markdown

Optional pairing:

1. Claude writes analysis in markdown (using all-dialogue skill)
2. You embed triples in the markdown as you read
3. Run scanner on the output file → see structure
4. Use matrix to:

· Ask follow-up questions · Spot gaps · Verify causality chains

Example workflow:

User: "Analyze scheduler design. Save as scheduler-analysis.md"
Claude: [saves full analysis to scheduler-analysis.md]

User: [reads md, embeds triples]
<<{async_dispatch, reduces, latency}.
<<{latency, affects, throughput}.

User: "Run scanner on scheduler-analysis.md"
Scanner: [adjacency matrix]

User: [examines matrix] "What about error propagation?"

No requirement to use all-dialogue — works standalone on any markdown.

Workflow

Standalone Use

1. Write markdown with embedded triples
2. Place scanner.py in same directory
3. Run: python scanner.py
4. Get compressed adjacency matrix
5. Use for analysis or feed back to AI

With all-dialogue Pairing

1. Ask Claude to save analysis to markdown (all-dialogue skill)
2. Read markdown, mark critical relations with triples
3. Run scanner
4. Iterate: use matrix to ask more precise questions

Philosophy

· Why separate from all-dialogue? All-dialogue manages token flow (thinking + response → file). Narrative-topology manages semantic extraction (relations → matrix). Independent concerns. Both can upgrade separately. Narrative-topology applies to any markdown, not just Claude output. · Why triples instead of prose summaries? Prose is lossy. Easy to miss connections. Triples are canonical, computable, greppable. Matrix enables quantitative analysis (paths, cycles, centrality). Scales: 50 triples → clear structure. 500 triples → still manageable. · Why Python? Ubiquitous, no extra dependencies. Single file, runs anywhere. Clear, readable, and easily extensible.

Summary

Narrative Topology extracts relational structure from dense text.

· Input: Markdown with <<{S, P, O}. triples · Processing: Python scanner parses + expands cartesian products · Output: Adjacency matrix compressed with x::n notation (low token cost, AI‑friendly) · Power: See causal chains, bottlenecks, cycles in long discussions · Scope: Works standalone. Pairs naturally with all-dialogue.

Use it to maintain signal in long, complex narratives.
