English-Catalan Neural Machine Translation in the Biomedical Domain through the cascade approach

TL;DR

This paper presents a neural machine translation system for English-Catalan biomedical texts using a cascade approach via Spanish, addressing low-resource challenges and introducing a new test dataset.

Contribution

It introduces a cascade pivot strategy for English-Catalan biomedical translation and provides a new test dataset for evaluation.

Findings

Effective translation performance demonstrated

New English-Catalan biomedical test dataset created

Cascade approach improves low-resource translation quality

Abstract

This paper describes the methodology followed to build a neural machine translation system in the biomedical domain for the English-Catalan language pair. This task can be considered a low-resourced task from the point of view of the domain and the language pair. To face this task, this paper reports experiments on a cascade pivot strategy through Spanish for the neural machine translation using the English-Spanish SCIELO and Spanish-Catalan El Peri\'odico database. To test the final performance of the system, we have created a new test data set for English-Catalan in the biomedical domain which is freely available on request.
