针对电力领域语料规模小、实体嵌套、实体缩写等特点,提出基于文本特征增强的实体识别方法。首先,通过预设词库和低粒度分词的方式,在合理利用中文单词蕴含的语义信息的同时,降低分词传递误差的影响。其次,设计词级双向门控循环单元学习中文单词构造特征,融合词性和词长特征后,与单词向量拼接成为单词增强向量。然后,基于双向门控循环单元-注意力机制-条件随机场完成实体识别模型的构建和训练。在此基础上,采用电力领域语料库进行验证,F1分数为87.02%,证实了电力命名实体识别效果。
Considering the characteristics of small scale
nested entities and abbreviated entities for electric corpus
the named entity recognition (NER) method based on enhanced text features is proposed. Firstly
by the way of the low-grain word segment and the preset dictionary
the semantic information in Chinese words is properly utilized
and the transmission errors caused by word segment are decreased. Secondly
the structure features of a single Chinese word are learned by the word-level bidirectional gated recurrent unit (Word BiGRU). Together with the features of the part of speech for words and word length
the enhanced word vector is built by concatenating these feature vectors with word vectors. Finally
the NER model is designed with BiGRU
attention mechanism and conditional random field (CRF). The proposed method is verified by using electric corpus and F1 score reaches 87.02%
which proves the effectiveness of NER for electric power industry.
