text2signed-graph — Gold Standard (Synthetic v2)

A synthetic benchmark for extracting signed political relation graphs from news articles. Each relation is a directed, signed triple between political actors: (actor_u → act_type → actor_v, polarity), grounded in an evidence quote.

Built to evaluate text2SG extraction pipelines (NER → entity resolution → relation extraction) in a precision-first setting, with planted distractors to penalize over-extraction.

Contents

File Rows Description
relations_full.parquet 914 the signed graph, denormalized & human-readableactor_u → act_type → actor_v, polarity with actor names + article metadata. Start here.
articles.parquet 282 input — synthetic news articles (incl. distractors)
nodes.parquet 1,579 graph nodes (actors per article) — normalized form
gold.parquet 914 graph edges (by union_id) — normalized form
split.json train (207) / test (75) article split + seed
unions.json raw nested form of the nodes

relations_full.parquet schema (start here — viewer-friendly)

article_id, actor_u, act_type, actor_v, polarity (the signed edge), u_type, v_type, is_reactive, issue, evidence_quote, source, dispute_type, title, dominio, dureza, es_distractor. Each row is one gold edge actor_u → act_type → actor_v (polarity) with everything joined in.

The signed graph (the core)

Each article has a gold signed graph: nodes.parquet (actors) + gold.parquet (signed edges between them). Join them on (article_id, union_idu_from/u_to).

nodes.parquet schema (the actors)

article_id, union_id (e.g. U7), type (roster_actor = known political figure / institutional_actor / non_roster_actor), canonical_name, surfaces (alias list). 1,579 nodes total.

gold.parquet schema (the signed edges)

article_id, u_from, u_to (→ nodes.union_id), act_type (e.g. endorses, attacks, allies_with, questions…), polarity (positive / negative / neutralthe edge sign), is_reactive, issue, evidence_quote, source (planted / …), n_inclusion_votes, dispute_type.

articles.parquet schema (the input)

article_id, title, body, dominio (topic), dureza (relation difficulty: explicita / mixta / oblicua), es_distractor (distractor flag).

Why synthetic

Real Chilean political news carry copyright (CC-BY-NC). This synthetic gold reproduces the register, difficulty, and structure of real coverage — including distractor articles and near-miss relations — so it can be shared openly as a reproducible benchmark.

Evaluation

Score a predicted relation set against gold.parquet on the test split. The reference extractor (id15 / gemini_champion_v2) reaches f0.5 ≈ 0.89 on detection (undirected), precision-first. Distractors and dispute_type test robustness to over-extraction.

Lineage

This gold standard was built and used to develop the text2SG extraction pipeline:

  1. text2graph-evolve — evolutionary engine that optimizes extraction prompts/genomes against this gold (fitness = f0.5, precision-first). The champion extractors (id15, gemini_champion_v2) were evolved here.
  2. chilean-political-dataset-signed-networks — applies those champions at scale to build a signed political network of Chile (2014–2026): ~480k articles → 442k actor nodes, 2.5M signed edges.

So the flow is: this gold → evolve the extractor → run it on real news → signed graph.
