摘要:

大多数用于命名实体识别(NER)的最先进的方法使用词簇和词典形式的半监督信息。最近,已经探索了基于神经网络的语言模型,因为它们作为副产品生成词的高度信息化的向量表示,称为词嵌入。在本文中,我们提出了两个贡献:一种新的形式的学习词嵌入,可以利用相关词汇的信息,以改善表示,和第一个系统使用神经词嵌入,以实现国家的最先进的结果,命名实体识别在CoNLL和Ontonotes NER。我们的系统在CoNLL 2003的测试集上获得了90.90的F1分数-明显优于以前任何基于公共数据训练的系统,并与采用大量私有工业查询日志数据的系统相匹配。

英文摘要:

Most state-of-the-art approaches for named-entity recognition (NER) use semi supervised information in the form of word clusters and lexicons. Recently neural network-based language models have been explored, as they as a byproduct generate highly informative vector representations for words, known as word embeddings. In this paper we present two contributions: a new form of learning word embeddings that can leverage information from relevant lexicons to improve the representations, and the first system to use neural word embeddings to achieve state-of-the-art results on named-entity recognition in both CoNLL and Ontonotes NER. Our system achieves an F1 score of 90.90 on the test set for CoNLL 2003---significantly better than any previous system trained on public data, and matching a system employing massive private industrial query-log data.
