GastroCorp NER

Gastronomic Named Entity Recognition in Spanish–English Texts

Overview

The gastronomic domain presents distinctive challenges for Natural Language Processing. Terms such as arepa de choclo, ají amarillo, or tacos al pastor carry cultural identity and semantic specificity that demand precise entity recognition before downstream tasks like machine translation or recipe recommendation can be performed reliably.

GastroCorp NER 2026 is a shared task over a bilingual (Spanish–English) gastronomic corpus. Participants must assign an IOB2 entity label to tokens from restaurant menus or culinary recipes.

Organization

Universidad Tecnológica de Bolívar
Cartagena, Colombia.
