This project provides a structured equity research database covering 1,735 Taiwan-listed companies, consolidating fragmented public information into a searchable knowledge graph. It targets engineers, researchers, and power users needing to analyze Taiwan's critical role in global supply chains, offering detailed business overviews, supply chain mapping, and financial data. The core benefit is a deep, cross-referenced understanding of company relationships and market dynamics.

How It Works

The project consolidates disparate public information into a consistent, searchable format centered around a wikilink-based knowledge graph. This graph, comprising over 4,900 links, enables granular cross-referencing of companies, technologies (e.g., [[CoWoS]]), and materials (e.g., [[光阻液]]). It integrates business descriptions, supply chain mapping, customer/supplier relationships, and financial data, allowing users to discover and analyze complex interdependencies within Taiwan's industrial ecosystem.

Quick Start & Requirements

Installation involves cloning the repository and installing Python dependencies: pip install yfinance pandas tabulate. The project primarily utilizes local Python scripts for data updates and analysis, requiring a standard Python environment. No specific hardware or GPU is mandated for local script execution. Key outputs like the interactive network graph (network/index.html) and thematic screens (themes/README.md) can be opened directly in a browser.

Highlighted Details

• Knowledge Graph: A comprehensive network of 4,900+ wikilinks maps supply chains and technology ecosystems, enabling detailed queries like [[Apple]]'s Taiwanese suppliers or companies involved in [[CoWoS]].
• Thematic Investment Screens: Generates detailed supply chain maps for key investment themes such as AI servers, electric vehicles, and 5G infrastructure.
• Interactive Network Graph: Visualizes wikilink co-occurrences across all tickers using D3.js, offering an interactive exploration of relationships.
• Data Scope: Covers 1,735 Taiwan-listed companies across 99 industry sectors, with financial data sourced from yfinance.

Maintenance & Community

The README does not detail specific contributors, sponsorships, or community channels like Discord or Slack. The project structure and quality standards suggest a methodical development approach.

Licensing & Compatibility

The project is released under the MIT License, which generally permits commercial use and integration into closed-source projects. Financial data is sourced via yfinance from Yahoo Finance, and business descriptions are original research.

Limitations & Caveats

Financial data availability is contingent on yfinance, potentially leading to gaps for some OTC stocks. Business descriptions are static snapshots and do not auto-update with new developments. New technologies or companies require manual addition to the wikilink curation. All content is in Traditional Chinese, necessitating translation for English-speaking users. AI-driven enrichment features consume API tokens, while core Python scripts operate locally and are free.
