摘要:

在向量空间中捕捉词的语义关系有助于许多自然语言处理任务。一种很有前途的方法利用词汇句法模式作为词对的特征。在本文中,我们提出了一种新的模型,这种模式为基础的方法,神经潜在关系分析(NLRA)。NLRA可以概括词对的共现和词汇句法模式,并获得不共现的词对的嵌入。这克服了以前的模式为基础的模型中遇到的关键数据稀疏问题。我们在测量关系相似性上的实验结果表明,NLRA优于以前的基于模式的模型。此外,当与向量偏移模型相结合时,NLRA实现了与利用附加语义关系数据的最新模型相当的性能。

英文摘要:

Capturing the semantic relations of words in a vector space contributes to many natural language processing tasks. One promising approach exploits lexico-syntactic patterns as features of word pairs. In this paper, we propose a novel model of this pattern-based approach, neural latent relational analysis (NLRA). NLRA can generalize co-occurrences of word pairs and lexico-syntactic patterns, and obtain embeddings of the word pairs that do not co-occur. This overcomes the critical data sparseness problem encountered in previous pattern-based models. Our experimental results on measuring relational similarity demonstrate that NLRA outperforms the previous pattern-based models. In addition, when combined with a vector offset model, NLRA achieves a performance comparable to that of the state-of-the-art model that exploits additional semantic relational data.
