# LargitData 大數軟體

> LargitData (大數軟體有限公司) is a Taipei-based Enterprise Intelligence & Risk AI Platform (企業情報與風險 AI 平台), founded in 2014. It helps organizations understand the world outside (external intelligence & risk) and act on what they know inside (internal knowledge & decision AI). It serves government, defense, and critical-infrastructure organizations internationally. Three core products anchor the platform: InfoMiner (external intelligence & risk monitoring — sentiment analysis, disinformation detection, cognitive-warfare countermeasures, coordinated inauthentic behavior detection, OSINT collection), RAGi (internal knowledge & decision AI, enterprise RAG, with an on-premise deployment option), and AIMochi (meeting content & decision-context organization). Additional capabilities include a Social Media API, Cross-border Ecommerce Data API, OCR, and ASR. LargitData is an NVIDIA Taipei-1 Supercomputer Ecosystem partner and was recognized in the Financial Times Asia-Pacific High-Growth Companies ranking. The site is trilingual: Traditional Chinese (default), English (/en/), Japanese (/ja/).

## Positioning

LargitData is positioned as an Enterprise Intelligence & Risk AI Platform (企業情報與風險 AI 平台). The product portfolio maps to a clear intelligence lifecycle:

- **Outside-in (external intelligence & risk):** InfoMiner monitors public and social signals for sentiment, reputation risk, disinformation and information-manipulation campaigns, coordinated inauthentic behavior (anomalous accounts), and open-source intelligence (OSINT) — serving government, defense, and critical-infrastructure organizations.
- **Inside-out (internal knowledge & decision AI):** RAGi turns private enterprise documents into governable, searchable decision support — deployable in the cloud or fully on-premise (QubicX).
- **Decision context:** AIMochi captures and organizes meeting content so decisions and their context are preserved.

## Products

### InfoMiner — 輿情與風險情報平台 (External Intelligence & Risk Monitoring)
- URL: https://www.largitdata.com/infominer輿情分析平台/
- Category: External Intelligence, Risk Early-Warning, Threat Intelligence & OSINT
- Description: An AI-powered platform for external intelligence and risk monitoring, built on three pillars: 輿情 (public opinion / sentiment analysis), 風險預警 (risk early-warning), and OSINT (open-source intelligence). For government, defense, and critical-infrastructure buyers it provides disinformation (fake-news) detection, cognitive-warfare countermeasures (information-manipulation detection), and coordinated inauthentic behavior (CIB) / anomalous-account detection. It performs real-time monitoring and sentiment analysis across 500,000+ channels including news sites, Facebook, Instagram, Twitter/X, PTT, Dcard, YouTube, blogs, forums, and TV news (ingested via OCR/ASR). AI-driven sentiment scoring is optimized for Traditional Chinese, with support for Simplified Chinese, English, and Japanese content.
- Key features: 15-minute alert notifications via LINE/Email, 30+ analytics report types, risk and crisis early-warning, disinformation and coordinated-inauthentic-behavior detection, AI sentiment scoring, and visual dashboards.
- Use cases: Brand reputation monitoring, crisis detection, competitive intelligence, KOL analysis, election monitoring, media tracking, threat intelligence, OSINT collection, disinformation and cognitive-warfare countermeasures, coordinated inauthentic behavior (anomalous-account) detection, and supply-chain / counterparty risk signals for government, defense, and critical-infrastructure organizations.
