Abstract

Risk incidents in the banks' systems have caused significant social impacts and economic losses. This study proposes a risk incident knowledge modeling and analysis approach based on the knowledge graphs to realize the effective integration and continuous accumulation of incident knowledge. The authors are the first to analyze the advantages of knowledge graphs in risk incident knowledge integration for the bank's core system. Moreover, they study and compare the related field's state-of-the-art models (including CRF, BiLSTM, BiLSTM-CRF, BERT-BiLSTM-CRF). This paper proposes an improved Bert-BiLSTM-CRF model to perform entity recognition which replaces “individual word mask and training” with “full word mask and training” targeted to solve the problem of low accuracy in the extraction of incident text entities in the banking system. Experiments on 1000 banking system incident material show that the improved Bert-BiLSTM-CRF model outperforms the state-of-the-art models based on the comparison of recall (R), precision (P), and F1-measure, with a 2%-9% improvement in the F1-measure.

Introduction

Banks’ financial transactions, which involve the operation of client funds, contribute significantly to the growth of the national economy. As a result, banks have stringent requirements for the timeliness and consistency of transactions and data, which must be accurate, secure, usable, and traceable (Krause & Giansante, 2018). In the banking IT system, the construction of the core banking system accounts for the most significant and complex overall expenditure. High-tech projects require considerable capital and continuous human resource investment and involve the cooperation or coordination of the related systems of the entire bank (Q. Zhao et al., 2020). Although both the technology and management of the core banking system have advanced significantly after decades of experience, risk incidents still occur occasionally. According to the report from the China Banking Regulatory Commission, risk incident information and investigation reports released by various local supervisory and management departments, as well as news reports from mainstream media and other sources, data of risk incidents that occurred in the bank’s core system from 2021 to 2022 (cc, 2022; China, 2022; Cngold, 2022; Jingwei, 2022; NTES, 2022; Finance, 2022; Jiemian, 2022; JRQ, 2022; Zaobao, 2022) were collected. These are shown in Table 1, indicating that both influence and economic losses are on the rise. The situation regarding risk management in the development of the core banking system is still severe. Core banking system incidents have significant economic and social impacts but provide valuable experience for implementing subsequent bank projects. By analyzing incidents related to the core banking system, we can better understand the causes of these incidents, providing valuable insights for incident prevention.
