Abstract

The shared task GUA-SPA at IberLEF 2023 involves detecting and analyzing code-switching in Guarani and Spanish through language identification, named entity recognition, and classifying the usage of Spanish in code-switched contexts, with varied results among teams.

AI-generated summary

We present the first shared task for detecting and analyzing code-switching in Guarani and Spanish, GUA-SPA at IberLEF 2023. The challenge consisted of three tasks: identifying the language of a token, NER, and a novel task of classifying the way a Spanish span is used in the code-switched context. We annotated a corpus of 1500 texts extracted from news articles and tweets, around 25 thousand tokens, with the information for the tasks. Three teams took part in the evaluation phase, obtaining in general good results for Task 1, and more mixed results for Tasks 2 and 3.
