Laptop-ACOS

Laptop-ACOS是2017年和2018年从亚马逊平台收集的全新笔记本电脑数据集（涵盖华硕、宏碁、三星、联想、MBP、微星等六大品牌的十种笔记本电脑）。它包含 4,076 个评论句子，比 SemEval 笔记本电脑数据集大得多。
对于笔记本电脑-ACOS，我们自己注释了四个元素及其对应的四元组。我们使用 SemEval 2016 笔记本电脑数据集中定义的方面类别。 Laptop-ACOS 数据集包含 4076 个句子和 5758 个四元组。正如我们所提到的，很大一部分四元组包含隐含的方面或隐含的意见。通过比较两个数据集，可以观察到，Laptop-ACOS 的隐含意见比例高于 Restaurant-ACOS。值得注意的是，Laptop-ACOS 适用于 ABSA 中的所有子任务，包括基于方面的情感分类、方面-情感对提取、方面-观点对提取、方面-观点情感三元组提取、方面-类别-情感三元组提取， ETC。

Laptop-ACOS is a brand-new laptop dataset collected from the Amazon platform in 2017 and 2018, covering 10 laptop models from 6 major brands including ASUS, Acer, Samsung, Lenovo, MBP, and MSI. It contains 4,076 review sentences, which is considerably larger than the SemEval Laptop Dataset. For the Laptop-ACOS dataset, we manually annotated four elements and their corresponding quadruples. We adopted the aspect category definitions from the SemEval 2016 Laptop Dataset. The Laptop-ACOS dataset consists of 4,076 sentences and 5,758 quadruples. As previously mentioned, a large proportion of these quadruples contain implicit aspects or implicit opinions. By comparing the two datasets, it can be observed that the proportion of implicit opinions in Laptop-ACOS is higher than that in Restaurant-ACOS. Notably, Laptop-ACOS is applicable to all subtasks in Aspect-Based Sentiment Analysis (ABSA), including aspect-based sentiment classification, aspect-sentiment pair extraction, aspect-opinion pair extraction, aspect-opinion-sentiment triple extraction, aspect-category-sentiment triple extraction, etc.
