We present a novel learning method for word embeddings designed for relation classification. Our word embeddings are trained by predicting words between noun pairs using lexical relation-specific features on a large unlabeled corpus. This allows us to explicitly incorporate relation-specific information into the word embeddings. The learned word embeddings are then used to construct feature vectors for a relation classification model. On a well-established semantic relation classification task, our method significantly outperforms a baseline based on a previously introduced word embedding method, and compares favorably to previous state-of-the-art models without syntactic information or manually constructed external resources. Furthermore, when incorporating external resources, our method outperforms the previous state of the art.

本文介绍了一种新颖的学习方法，用于关系分类的单词嵌入训练，并使用无标注语料库上的词汇关系特定特征预测名词对之间的单词，以将关系特定信息显式地纳入单词嵌入中。通过使用所学习的单词嵌入来构建特征向量，用于关系分类模型。在一个基于语义关系分类任务中，我们的方法表现显著优于基于之前介绍的单词嵌入方法的基准线，并与使用句法信息或手动构造的外部资源的先前最先进的模型相比，表现出了比较良好的结果。
