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.

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_id ↔ u_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 /
neutral — the 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:
- 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. - 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.
