OpenCor: Latin American and Iberian Languages Open Corpora Forum

Paper · 2026 · Livy Real and Valeria de Paiva

Summary

Open corpora and lexical resources are scarce and hard to locate for the languages spoken across Latin America and on the Iberian Peninsula, especially indigenous, minority and regional varieties. Information about them is scattered across personal pages, repositories and proceedings. This paper is a historical report on OpenCor, a community forum launched to catalogue and discuss such resources. OpenCor deliberately emphasizes data creation, licensing, sustainability and collaboration over system competitions or shared tasks.

The authors trace its origins to a 2018 LDC meeting in Mexico City and its inspiration from Linguateca. They describe five workshop editions held between 2018 and 2024, analyse submission and acceptance figures, and survey the variety of resources presented. They also discuss recurring obstacles, chiefly the lack of travel funding, which kept some accepted authors from presenting.

The main finding is that submissions stayed steady even without grants or competitive incentives. This suggests OpenCor works as long-term community infrastructure. The report preserves institutional memory and offers a model for future openness-oriented initiatives.

Key points

  • Five editions: Canela, Brazil (PROPOR 2018); Guanajuato, Mexico (PLAGAA 2019); Évora, Portugal (PROPOR 2020, hybrid); online (STIL 2021, first full-day edition); Santiago, Spain (PROPOR 2024, no keynote).
  • Totals: 49 submissions and 39 acceptances (≈80%), with yearly acceptance ranging from 64% in 2024 to 100% in 2021.
  • In 2018, three of the eight accepted papers went unpresented for lack of funding. That edition was the only one with direct financial support for the invited speaker.
  • Access was kept low-cost through free EasyChair reviewing, workshop-only registration, non-archival submissions, and keynotes who needed no travel funding.
  • The name combines "Open Corpora" with Latin cor ("heart"). The forum's archive is hosted at opencor.gitlab.io.
