About this paper
Liyang Wang, Yu Cheng, Ao Xiang, Jingyu Zhang, Haowei Yang
An interdisciplinary research team developed an NLP and deep learning framework to detect financial risks from unstructured text data, demonstrating that Long Short-Term Memory (LSTM) models achieved the highest accuracy of 92.5% in identifying various risk types from financial reports.
Key insights
- Robust text data preprocessing and advanced feature extraction methods like TF-IDF and Word2Vec are critical for enhancing model accuracy in financial risk detection.
- Analysis of financial reports using NLP can effectively identify main risk themes and link specific financial indicators to potential company vulnerabilities.
- Deep learning models, particularly LSTM, demonstrate superior performance in capturing complex relationships and long-range dependencies in textual data for financial risk detection compared to traditional machine learning algorithms.
