BiverWordle is an innovative visualization system specifically designed to analyze, visualize, and authenticate sentiments relating to stock trends within financial text forums. This system ingeniously merges a time-series financial data representation, which is inspired by a candlestick chart, with a stacked area chart/streamgraph derived from text classification results. It further integrates word clouds that are uniquely arranged in the shapes of sad, neutral, and happy smiley face ideograms. These combined elements provide a comprehensive and intuitive portrayal of stock market sentiment.

The name "BiverWordle" encapsulates the essence of our approach, alluding to two river-like area charts flowing with words. Our system's effectiveness is evaluated through various measures. These include text classification metrics (accuracy, precision, recall, and F1-score) for test data, and additionally, three use cases that vividly demonstrate the interactive data exploration possibilities of our visualization tool.

The paper has been accepted at VINCI 2023 as a short paper!

• Integration of multiple visualization techniques for a comprehensive understanding of stock market sentiment.
• Analysis of Chinese financial text data to understand and visualize market trends.
• Validation of our system using three different stock trend scenarios.
• Exploration of potential improvements in both the financial text classification and visualization aspects of the project.

• Text Classification: BiverWordle employs text classification algorithms, such as textCNN and BERT, to analyze and categorize financial text data from forums.
• Visualization: BiverWordle combines various visualization techniques, including K-Line diagrams, Theme River, and Word Cloud, to represent stock trends and sentiments.

• Data Source: The data source is from 互动易, provided by Prof. LI Yuelei, Tianjin University. We identified eight categories within the data:

  Index	Category	Index	Category
  0	宏观政策 (Macroeconomic Policy)	4	产品及服务 (Products and Services)
  1	业务动态 (Business Dynamics)	5	股票情况及政策 (Stock Status and Policy)
  2	收益能力 (Earning Ability)	6	股票价格波动 (Stock Price and Volatility)
  3	财务情况 (Financial Situation)	7	其他 (Others)

• Checkpoints: The checkpoints are available in Google Drive

The dataset is partitioned into 11,915 texts for training, 3,910 for testing, and 3,910 for validation, adhering to a 6:2:2 ratio. We use three models: textCNN, BERT, and Voting. Here are the experiment results for these models:

The Accuracy of Each Model:

Incorporating G2 into BiverWordle allows you to create interactive and visually appealing charts to enhance your analysis and presentation of stock market sentiment. G2 is a powerful visualization library that provides a wide range of chart types and customization options.
