From Semantic Roles to Opinion Roles: SRL Data Extraction for Multi-Task and Transfer Learning in Low-Resource ORL
PositiveArtificial Intelligence
The recent report outlines a comprehensive methodology for creating a high-quality Semantic Role Labeling (SRL) dataset derived from the Wall Street Journal section of the OntoNotes 5.0 corpus, specifically tailored for Opinion Role Labeling (ORL) tasks. By utilizing the PropBank annotation framework, the authors have successfully implemented a reproducible extraction pipeline that meticulously aligns predicate-argument structures with surface text. This process has resulted in a robust dataset comprising 97,169 predicate-argument instances, clearly defining roles such as Agent (ARG0), Predicate (REL), and Patient (ARG1), which are mapped to the ORL's Holder, Expression, and Target schema. The significance of this work lies in its potential to enhance opinion mining, particularly in low-resource environments, by offering a reusable resource for researchers aiming to leverage SRL for ORL applications. The detailed account of extraction algorithms, handling of discontinuous arguments, an…
