基于多模态数据语义融合的旅游在线评论有用性识别研究
行文架构
引言
相关工作
在线评论有用性识别
多模态数据融合
基于多模态数据融合的在线评论有用性识别模型
模型输入层为：给定的包含图片和文本的评论内容
模型输出层为：对应的有用性标签取值，0为无用评论，大于0为有用评论
文本语义特征提取
1、传统分词法W2V
2、BERT
注：BERT模型分词步骤，本文献介绍过于简单，后续有相关文献采用该技术时，笔者再来补全。
图片语义特征提取
图片标签识别
标签语义向量提取
图文特征融合与模型构建
采用基于文本卷积神经网络（TextCNN）和双向长短时记忆循环神经网络（bi-directional LSTM RNN）2个深度学习模型构建分类器
