# Profile Metrics

Corpus-local bibliometric + social-network metrics over the co-author and
citation graphs (NetworkX-equivalent, no graph library).

## How to run

```bash
aiwg corpus profile-metrics                 # per-PROF-P table to stdout
aiwg corpus profile-metrics --papers        # per-paper CD-index + PageRank
aiwg corpus profile-metrics --out indices/metrics.md
```

Per person (PROF-P): **h-index** (Hirsch), **mean CD-index** (Wu-Wang-Evans
disruption), **mean PageRank**, **betweenness** + **eigenvector** centrality on
the co-author graph, and an **influence grade** (h≥3→A, ≥2→B, ≥1→C, else D).
Per paper (`--papers`): CD-index + PageRank.

> CD-index is null for papers with < 3 in-corpus citers (low confidence). The
> node2vec embedding metrics are an opt-in add-on (needs-infrastructure), not
> computed here.
