Related Datasets

This is a single-season dataset containing entities and events as extracted from Season 20 screenplays.

• Megagraph (all seasons unified): brandburner/doctorwho-mega-narrative-kg

Note: The megagraph is not a simple union of season datasets. Cross-season entities are reconciled through a Global Entity Registry (GER), receiving new canonical UUIDs and distilled descriptions. Graph Gravity tiers are recalculated across all episodes. Use individual season datasets for single-season analysis; use the megagraph for cross-season analysis.

Layout method (schema ≥ 1.2.0): Coordinates are derived from the entities' semantic text embeddings (UMAP with a fixed seed and PCA initialization), so narratively similar entities sit near each other. Non-embedded nodes (events, scenes, episodes, etc.) are placed at the weighted barycenter of their narrative neighbours. The layout is deterministic: re-exporting an unchanged graph reproduces identical coordinates, and lightly-changed graphs keep comparable layouts. Not comparable with positions published under schema ≤ 1.1.0, which used a non-deterministic node2vec structural embedding. See meta.json → positions for the exact method and coverage stats.

Usage

from datasets import load_dataset
import pandas as pd

# Load from HuggingFace
ds = load_dataset("brandburner/doctorwho-s20-narrative-kg")

# Or load parquet directly
nodes = pd.read_parquet("nodes.parquet")
edges = pd.read_parquet("edges.parquet")

# Filter to anchor characters
anchors = nodes[(nodes['primary_label'] == 'Agent') & (nodes['tier'] == 'anchor')]

# Build a NetworkX graph
import networkx as nx
G = nx.DiGraph()
for _, n in nodes.iterrows():
    G.add_node(n['node_id'], label=n['primary_label'], name=n['name'])
for _, e in edges.iterrows():
    G.add_edge(e['source_node_id'], e['target_node_id'], type=e['relationship_type'])
