Antitrust Radar research architecture

Research Topic Comparison Studio

Compare research topics, publication histories, and shared evidence. Missing coverage remains visible and is not treated as a zero economic outcome.

Comparison standard. Topics connect only through exact publication IDs, agenda-question IDs, issue-program IDs, dataset IDs, or route paths. Shared custody does not establish shared findings, methods, importance, legal relevance, or causation.

0 structural-zero cells remain across the selected contracts. A zero records the current editorial inventory, not the absence of relevant real-world evidence.

Shared custody map

Only exact repeated identifiers create an edge

Comparison boundary. Research topics are editorial navigation contracts assembled from exact publication themes and declared links to agenda questions, issue programs, datasets, and analytical routes. A topic does not create a legal market, make unlike units comparable, rank research importance, or establish market power, harm, liability, policy performance, welfare, or causation. Structural zeros remain visible as current coverage gaps.

Reproducibility contract

One selection, exact memberships, reusable rows.

The studio derives every matrix cell, edge, and register row from the same topic model published through the public data endpoint.

01

Exact join keys

Publication, agenda, issue, and dataset identifiers plus canonical route paths create the comparison ledger.

02

Visible structural zeros

Empty membership lanes remain explicit and are never imputed from adjacent research programs.

03

Portable evidence

Selected topic summaries and membership-level comparison packets are available as JSON and CSV.
