About
International Corpus Network of Asian Learners of English annotated with Argumentative Structure and Sentence Reordering ("ICNALE-AS2R" corpus)
This language resource is a collection of English learner essays which are excepted from ICNALE, based on two criteria: grammatical error free and moderately scored. The corpus consists of 434 essays. The corpus includes two layers of annotation.
•The first layer is an argumentative structure annotation. In the argumentative structure annotation, sentences are first differentiated into argumentative and non-argumentative components; then, relations are established between argumentative components to form a hierarchical structure of the text. We refer the corpus with the first annotation layer as "ICNALE-AS."
•The second layer is a sentence rearrangement annotation, which improves text coherence and organisation qualities. Rearrangement may cause irrelevant or incorrect referring and connective expressions. To correct these, text repair also follows after sentence rearrangement annotation, e.g., replacing pronouns with their referents or editing inappropriate connectives, to retain the original meaning of the text. We refer the corpus with the first and second annotation layers as "ICNALE-AS2R."
The annotation was conducted using the TIARA annotation tool. To visualise the annotation, you may open the essays using the tool, which is available for free at the following site: https://wiragotama.github.io/TIARA-annotationTool/
