Financial data analysis application via multi-strategy text processing

Abstract

Maintaining financial system stability is critical to economic development, and early identification of risks and opportunities is essential. The financial industry contains a wide variety of data, such as financial statements, customer information, stock trading data, news, etc. Massive heterogeneous data calls for intelligent algorithms for machines to process and understand. This paper mainly focuses on the stock trading data and news about China A-share companies. We present a financial data analysis application, Financial Quotient Porter, designed to combine textual and numerical data by using a multi-strategy data mining approach. Additionally, we present our efforts and plans in deep learning financial text processing application scenarios using natural language processing (NLP) and knowledge graph (KG) technologies. Based on KG technology, risks and opportunities can be identified from heterogeneous data. NLP technology can be used to extract entities, relations, and events from unstructured text, and analyze market sentiment. Experimental results show market sentiments towards a company and an industry, as well as news-level associations between companies.

Design of Motion Damage Estimation Model Based on Improved Recursive Neural Network Algorithm

“…Joint representation learning network. To test whether this network can learn a unified representation [Zhu (2023a[Zhu ( , 2022a], we simplify the network by only keeping the standalone decoder. We refer to it as the joint representation learning (JRL) network, as shown in Figure 6.…”

Research on the Development Trend of Traditional Financial Industry Based on Blockchain Technology

“…This paper introduces a industry trend analysis framework FQP 2.0, which is dedicated to analyzing the development prospects, opportunities, and risks of various industries. FQP 2.0 is an updated version based on FQP 1.0 (Zhu 2022a), which updates the industry trend analysis method and conducts more research on statistical machine learning models and pre-trained language models (PLMs) in financial data analysis.…”
