Definition Frames:使用混合概念表示的定义
Definition Frames: Using Definitions for Hybrid Concept Representations
摘要:
单词表示的进步已经在下游NLP任务中显示出巨大的改进,但缺乏语义可解释性。在本文中,我们介绍了定义框架(DF),矩阵分布式表示提取的定义,其中每个维度是语义上可解释的。DF维度对应于Qualia结构关系:一组唯一定义术语的关系。我们的研究结果表明,DF具有竞争力的表现与其他分布式语义方法的单词相似性任务。
英文摘要:
Advances in word representations have shown tremendous improvements in downstream NLP tasks, but lack semantic interpretability. In this paper, we introduce Definition Frames (DF), a matrix distributed representation extracted from definitions, where each dimension is semantically interpretable. DF dimensions correspond to the Qualia structure relations: a set of relations that uniquely define a term. Our results show that DFs have competitive performance with other distributional semantic approaches on word similarity tasks.
