摘要:

两个语言单位的语义相关程度一直被认为是理解意义的基础。此外,自动确定相关性具有许多应用,例如问答和摘要。然而,由于缺乏相关性数据集,以前的NLP工作主要集中在语义相似性上,这是相关性的一个子集。在本文中,我们介绍了一个语义文本相关性数据集STR-2022,该数据集使用比较注释框架手动注释了5,500个英语句子对,从而得到细粒度的分数。我们表明,人类的直觉,句子对的相关性是高度可靠的,重复注释的相关性为0.84。我们使用数据集来探索是什么使句子语义相关的问题。我们还展示了STR-2022用于评估句子表示的自动方法和各种下游NLP任务的实用性。我们的数据集、数据声明和注释问卷可以在以下网站找到:https://doi.org/10.5281/zenodo.7599667

英文摘要:

The degree of semantic relatedness of two units of language has long been considered fundamental to understanding meaning. Additionally, automatically determining relatedness has many applications such as question answering and summarization. However, prior NLP work has largely focused on semantic similarity, a subset of relatedness, because of a lack of relatedness datasets. In this paper, we introduce a dataset for Semantic Textual Relatedness, STR-2022, that has 5,500 English sentence pairs manually annotated using a comparative annotation framework, resulting in fine-grained scores. We show that human intuition regarding relatedness of sentence pairs is highly reliable, with a repeat annotation correlation of 0.84. We use the dataset to explore questions on what makes sentences semantically related. We also show the utility of STR-2022 for evaluating automatic methods of sentence representation and for various downstream NLP tasks. Our dataset, data statement, and annotation questionnaire can be found at: https://doi.org/10.5281/zenodo.7599667
