PROFILE
Marcoagpinto
Marco Pinto enhanced the languagetool-org/languagetool repository by developing and refining Portuguese grammar and spelling rules, focusing on both PT-PT and Brazilian variants. He engineered rule-based systems using Java and XML, expanding disambiguation logic, formalizing new grammar checks, and integrating AI-assisted suggestions to accelerate rule maintenance. His work included extensive lexicon management, exception handling, and vocabulary enrichment, which improved accuracy and reduced false positives. Marco’s technical approach emphasized maintainability, with regular code cleanup, rule lifecycle management, and robust testing. The depth of his contributions ensured broader language coverage, higher reliability, and a more scalable foundation for future language tool development.

51 Commits • 8 Features
Oct 1, 2025October 2025 (languagetool-org/languagetool) — Concise monthly summary focused on improving disambiguation accuracy, robustness, and maintainability across Portuguese rules. Key features were delivered in disambiguation.xml with extensive enhancements, improved exception handling, and expanded coverage. Major bug fixes targeted disambiguation reliability and false positives in edge cases. The outcomes drive better user-facing accuracy, with more reliable parsing and decision logic across PT-PT and general Portuguese. Demonstrated strengths in XML rule authoring, Java-based tooling context, testing, and careful refactoring for maintainability.
