Sources & Methodology

Last updated: June 2026

How we collect

Tênis do Brasil runs an automated collection pipeline that monitors official Brazilian and international tennis sources. Collection runs daily and feeds an internal database, from which the editorial pipeline selects, generates, reviews and publishes content.

Monitored sources

We exclusively monitor official accounts — federations, tournaments and professional athletes:

Brazilian

  • CBT (Brazilian Tennis Confederation) — statements, results and call-ups (X @CBTenis, YouTube)
  • Rio Open — Rio de Janeiro ATP 500 tournament (@RioOpenTenis, YouTube)
  • SP Open — São Paulo WTA 250 tournament (@SPOpenWTA)
  • João Fonseca — athlete (@joaofonsecatennis, YouTube)
  • Beatriz Haddad Maia — athlete (@BiaHaddadMaia)
  • Luisa Stefani — athlete (@luisastefani)

International

  • ATP Tour — men's tour (@ATPTour, YouTube)
  • WTA — women's tour (@WTA, YouTube)
  • Roland Garros — Grand Slam (@rolandgarros, YouTube)
  • Wimbledon — Grand Slam (@Wimbledon, YouTube)
  • Australian Open — Grand Slam (@AustralianOpen, YouTube)
  • US Open — Grand Slam (@usopen, YouTube)
  • Davis Cup / Billie Jean King Cup — team competitions (@DavisCup, @BJKCup)

What we don't collect from

We do not collect from tabloids, betting sites, outlets without verifiable editorial standards, personal social media accounts unrelated to athletes or tournaments, or accounts with a history of misinformation. Influencers and specialized journalists are monitored separately and appear only in the Reactions section, never as a primary news source.

Editorial pipeline

Every collected item goes through the following steps before publication:

  1. Selection (assignment editor) — decides whether the item is news and what the journalistic angle is
  2. Generation (EN) — an English draft from the collected facts
  3. Translation (PT-BR) — into journalistic Brazilian Portuguese
  4. Editing — inverted pyramid, strong lede, subheads
  5. De-AI pass (copy edit) — rewrites to remove AI-generated text markers
  6. Deterministic gates — ban-list of artificial phrasing, dash limit, minimum burstiness
  7. 3 independent reviewers — editorial quality, ethics/facts, technical accuracy
  8. Publication — only articles approved by all 3 reviewers go live

Attribution and credits

Each published article states its primary source (organization, tournament or athlete that generated the information) and its production method (AI pipeline with review). No article is attributed to fictional human journalists — the opinion columns are explicitly labeled as AI content.

Photos and images: we never rehost images from athletes or photo agencies. Featured images are licensed via Unsplash (direct hotlink, attribution shown on the article). Pages without an available photo use our own SVG illustrations. Athletes appear on the site only via their own official social media embeds.

Limitations

The current pipeline does not have access to the official ATP/WTA live rankings and results API. Rankings shown on the site are reference values, not updated in real time. Integration with the official API is planned ahead of the portal's launch.
