IREKIER: An Easy Read Corpus for Basque and Spanish

Jesús Calleja, Thierry Etchegoyhen


Abstract
Easy Read (ER) text adaptation is one of the main means to provide accessible content for people with reading difficulties. ER text features aspects of text simplification, along with specific characteristics such as the need for short sentences, clearly structured content, and explanations for complex concepts. Support for ER text generation is still lacking overall, with few available resources to build automated systems upon. In this work, we describe the IREKIER corpus, based on ER news in Basque and Spanish from the Irekia transparency portal of the Basque Government. This corpus is currently one of the largest publicly shared resource to support training and evaluation of ER text adaptation models in these two languages, and the first of its kind for Basque. We describe our methodology to create the resource, along with the specific challenges raised by ER text. We also provide both intrinsic and extrinsic evaluations of the corpus, which is shared with the scientific community under a CC-BY-NC-ND 4.0 license.
