摘要

提出了一种改进的文本表示模型提取文本特征词向量方法。首先构建基于词典索引和所对应的词性索引的double word-embedding列表的word-embedding词向量，其次，利用在此基础上Bi-LSTM循环神经网络对生成后的词向量进一步进行特征提取，最后，通过mean-pooling层处理句子向量后且使用了softmax层进行文本分类。实验验证了Bi-LSTM和double word-embedding神经网络相结合的模型训练效果与提取情况。实验结果表明，该模型不但能较好地处理高质量的文本特征向量提取和表达序列，而且比LSTM、LSTM+context window和Bi-LSTM这3种神经网络有较明显的表达效果。

Abstract

Method of text representation model was proposed to extract word-embedding from text feature.Firstly

the word-embedding of the dual word-embedding list based on dictionary index and the corresponding part of speech index was created.Then

feature vectors was obtained further from these extracted word-embeddings by using Bi-LSTM recurrent neural network.Finally

the sentence vectors were processed by mean-pooling layer and text categorization was classified by softmax layer.The training effects and extraction performance of the combination model of Bi-LSTM and double word-embedding neural network were verified.The experimental results show that this model not only performs well in dealing with the high-quality text feature vector and the expression sequence

but also significantly outperforms other three kinds of neural networks

which includes LSTM

LSTM+context window and Bi-LSTM.
