# Survey Phase 0 — Quantitative IETF AI/Agent Draft Landscape

_Generated 2026-05-23 20:49 UTC by `scripts/survey-phase0.py` (deterministic, no LLM API calls)._

**Corpus definition ("clean IETF corpus"):** `source='ietf' AND (ratings.false_positive=0 OR NULL)`, joining `drafts d` with `ratings r` on `d.name=r.draft_name`. **N = 524 drafts.**

## 1. Author / Working-Group Concentration

- Distinct authors across the clean corpus: **619**
- Clean drafts with at least one resolved author in `draft_authors`: **396** of 524 (75.6%); the remainder have no rows in `draft_authors`.
- Total (author, draft) authorship memberships: **1193**

### Top 15 authors by clean-IETF draft count

| # | Author | Drafts |
| --- | --- | --- |
| 1 | Bing Liu | 22 |
| 2 | Nan Geng | 21 |
| 3 | Zhenbin Li | 20 |
| 4 | Qiangzhou Gao | 19 |
| 5 | Xiaotong Shang | 18 |
| 6 | Jianwei Mao | 14 |
| 7 | Guanming Zeng | 13 |
| 8 | Cullen Fluffy Jennings | 11 |
| 9 | Jonathan Rosenberg | 11 |
| 10 | Henk Birkholz | 10 |
| 11 | Qin Wu | 10 |
| 12 | Aijun Wang | 9 |
| 13 | Chongfeng Xie | 8 |
| 14 | Göran Selander | 8 |
| 15 | Luis M. Contreras | 8 |

### Concentration (top 10 authors)

- Top-10 authors account for **159 of 1193 authorship memberships (13.3%)**.
- Top-10 authors appear on **57 of 524 distinct clean drafts (10.9%)** (a draft is counted once even if multiple top-10 authors appear on it).

### Working groups

The `drafts.group` text column is effectively unpopulated for this corpus (only 524 drafts resolve to no/empty/'none' group, and the column has no real WG names). The meaningful grouping signal is `drafts.group_uri` (Datatracker group IDs).

- Drafts with no working group (group/1027 "individual" pseudo-group or null `group_uri`): **456** of 524.
- Distinct `group_uri` values: **28**.

Top 15 groups by `group_uri` (clean-IETF draft count):

| # | Group (Datatracker ID / label) | Drafts |
| --- | --- | --- |
| 1 | (individual / no WG) | 456 |
| 2 | group/2440 | 9 |
| 3 | group/2249 | 8 |
| 4 | group/2231 | 7 |
| 5 | group/2164 | 6 |
| 6 | group/1674 | 4 |
| 7 | group/1326 | 4 |
| 8 | group/1452 | 3 |
| 9 | group/38 | 2 |
| 10 | group/2430 | 2 |
| 11 | group/2380 | 2 |
| 12 | group/2317 | 2 |
| 13 | group/1956 | 2 |
| 14 | group/1921 | 2 |
| 15 | group/1718 | 2 |

> Note: ID 1027 is the Datatracker "none" pseudo-group for individually submitted drafts; it is not a real working group. Real WG/RG IDs are the remaining rows.

## 2. Embedding Overlap / Redundancy

- Embedding model: `nomic-embed-text`, dimension **768**, stored as float32 BLOB.
- Drafts embedded (clean corpus): **524** (100% coverage); pairwise comparisons: **137,026**.

### Pairwise cosine similarity (off-diagonal)

| Mean | Median | p90 | p99 | Max |
| --- | --- | --- | --- | --- |
| 0.7106 | 0.7110 | 0.7901 | 0.8497 | 1.0000 |

- Near-duplicate pairs (cosine > 0.9): **125**.
- Drafts with at least one near-duplicate (cosine > 0.9): **170** of 524 (32.4%).

## 3. Category Coverage Map

Primary category = first element of the `ratings.categories` JSON array. Sum check: **524 = 524** (OK).

- Drafts carrying more than one category: **487** of 524 (92.9%).
- Drafts with no category (uncategorized): **0**.

### Primary-category distribution + mean scores

Scores are 1-5 integers from `ratings`. `composite` = mean of the 5 dimensions (novelty, maturity, overlap, momentum, relevance) per draft, averaged over the category.

| Category | N | Share | Relevance | Composite | Novelty | Maturity | Overlap | Momentum |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
