收藏资源简介:
MEMD-ABSA是由南京理工大学计算机科学与工程学院创建的大规模多元素多领域数据集,专注于方面级情感分析。该数据集包含近20,000条评论句子和30,000个四元组,这些四元组被标注了明确的和隐含的方面和观点,适用于ABSA研究。数据集涵盖五个领域,支持多元素提取任务,旨在解决现有数据集在规模和领域覆盖上的不足。此外,数据集还支持开放领域的ABSA任务,以及挖掘隐含方面和观点的挑战。
MEMD-ABSA is a large-scale multi-element and multi-domain dataset developed by the School of Computer Science and Engineering, Nanjing University of Science and Technology, focusing on aspect-based sentiment analysis (ABSA). This dataset contains nearly 20,000 review sentences and 30,000 quadruples, where the quadruples are annotated with explicit and implicit aspects and opinions, making it applicable for ABSA research. Encompassing five distinct domains, the dataset supports multi-element extraction tasks, and is designed to address the limitations of existing datasets in terms of scale and domain coverage. Furthermore, the dataset supports open-domain ABSA tasks and tackles the challenge of mining implicit aspects and opinions.
