【喜讯】本所论文《 Analogical Reasoning on Chinese Morphological and Semantic Relations 》近日被自然语言处理领域最高级别学术会议ACL录用。ACL 2018将在2018年7月于澳大利亚墨尔本召开。

该论文基于神州泰岳-北京师范大学人工智能联合实验室中文词向量项目工作展开,针对当前中文词向量缺乏有效评测的问题,从语言学角度对中文词法与词义推理问题进行研究,提出了reduplication与semi-affixation两种隐性的词法推理模式,以及28种显性的语义推理关系。在此基础上,论文发布了CA8中文词类比推理数据集,并开源了36种覆盖不同领域训练语料、不同训练模型及训练特征的中文词向量。

摘要: Analogical reasoning is effective in capturing linguistic regularities. This paper proposes an analogical reasoning task on Chinese. After delving into Chinese lexical knowledge, we sketch 68 implicit morphological relations and 28 explicit semantic relations. A big and balanced dataset CA8 is then built for this task, including 17813 questions. Furthermore, we systematically explore the influences of vector representations, context features, and corpora on analogical reasoning. With the experiments, CA8 is proved to be a reliable benchmark for evaluating Chinese word embeddings.
