Blog Article

Financial fraud has extremely damaged the sustainable growth of financial markets as a serious problem worldwide.Nevertheless, it is fairly challenging to identify frauds with highly imbalanced dataset because ratio of non-fraud companies is very high compared to fraudulent ones.Intelligent financial statement fraud detection systems have therefore been developed to Neuw Rebel Skinny Eternal Black Jeans support decision-making for the stakeholders.

However, most of current approaches only considered the quantitative part of the financial statement ratios while there has been less usage of the textual information for classifying, especially those related comments in Chinese.As such, this paper aims to develop an enhanced system for detecting financial fraud using a state-of-the-art deep learning models based on combination of numerical features that derived from financial statement and textual data in managerial comments of 5130 Chinese listed companies’ annual reports.First, we construct financial index system including both financial and non-financial indices that previous researches usually excluded.

Then the textual features in MD&A section 7gm pravana of Chinese listed company’s annual reports are extracted using word vector.After that, powerful deep learning models are employed and their performances are compared with numeric data, textual data and combination of them, respectively.The empirical results show great performance improvement of the proposed deep learning methods against traditional machine learning methods, and LSTM, GRU approaches work with testing samples in correct classification rates of 94.

98% and 94.62%, indicating that the extracted textual features of MD&A section exhibit promising classification results and substantially reinforce financial fraud detection.
