摘要: 上市公司财务舞弊是指采用不当手段使会计信息失真的恶劣失信行为,对公司经营、经济发展和社会利益产生负面影响。目前,更多研究关注于金融数字数据,对文本信息和深度学习算法的研究较少,因此提出了一种基于深度学习并融合文本情感特征的上市公司财务舞弊识别方法。该方法首先对财务指标进行预处理,并使用Bi-LSTM提取股评文本的情感特征。然后使用RCC(residual-cross-convolutional)并行网络进行财务舞弊识别,其采取残差网络、交叉网络、卷积网络和长短期记忆网络并行的方式提取财务舞弊特征,并使用批标准化和全连接得到最终的识别结果。实验结果表明,该方法在识别上市公司财务舞弊的任务上较其他模型取得了更好的效果,召回率和AUC分别达到了88.46%和82.06%。

Abstract: Financial fraud of listed companies refers to the untrustworthy behavior of distorting accounting information by improper means, which has a negative impact on company operations, economic development, and social interests. At present, more research focuses on financial digital data, and less research on text information and deep learning algorithms. Therefore, a financial fraud recognition method for listed companies based on deep learning and textual emotional feature is proposed. Firstly, the method selects and preprocesses the financial indicators, and uses Bi-LSTM to extract the emotional features of the stock review text. Then, the method uses the RCC (residual-cross-convolutional) parallel network to recognize financial fraud. The network uses residual network, cross network, convolutional network and long short-term memory network to extract financial fraud features in parallel, and uses batch normalization and full connection to obtain the final recognition result. The experiment results show that this method achieves better results than other models in recognizing financial fraud for listed companies, with a recall rate and AUC of 88.46% and 82.06% respectively.
