摘要:

我们提出了监督方向相似性网络(SDSN),一种新的神经架构,用于在通用词嵌入之上学习特定于任务的转换函数。依赖于从特定任务的分数上的词汇子集的监督只有有限的量,我们的架构是能够概括和转换一个通用的分布式向量空间来建模的词汇蕴涵的关系。实验表明,分级词汇蕴涵的评分表现出色,将HyperLex数据集的最新水平提高了约25%。

英文摘要:

We present the Supervised Directional Similarity Network (SDSN), a novel neural architecture for learning task-specific transformation functions on top of general-purpose word embeddings. Relying on only a limited amount of supervision from task-specific scores on a subset of the vocabulary, our architecture is able to generalise and transform a general-purpose distributional vector space to model the relation of lexical entailment. Experiments show excellent performance on scoring graded lexical entailment, raising the state-of-the-art on the HyperLex dataset by approximately 25%.
