ATE_ABSITA dataset

The ATE_ABSITA dataset comprehends 4364 real user reviews, written in the Italian language, involving 23 products and collected from a famous eCommerce platform. Each sentence has been annotated by three subjects for its polarity, for the score assigned by the author, and for the presence of aspect terms. The dataset has been randomly divided into training, development and test sets. The data format used is NDJSON 1 with UTF-8 encoding and newline as delimiter. <p>The dataset has been produced and used in the context of the ATE_ABSITA task (http://www.di.uniba.it/~swap/ate_absita/index.html) during the Evalita 2020 evaluation campaign (http://www.evalita.it/2020).

ATE_ABSITA数据集包含4364条意大利语真实用户评论，涉及23款产品，数据采集自某知名电子商务平台。每条语句均由三名标注人员分别标注其情感极性、作者所给出的评分以及是否存在方面词（aspect terms）。该数据集已被随机划分为训练集、开发集与测试集。所采用的数据格式为NDJSON 1，编码格式为UTF-8，以换行符作为分隔符。
本数据集是在Evalita 2020评测活动（http://www.evalita.it/2020）中，围绕ATE_ABSITA任务（http://www.di.uniba.it/~swap/ate_absita/index.html）构建并投入使用的。
