OCR Optical Character Recognition

Combining OCR + LLM for high-precision document recognition and content understanding in secondsCombine OCR + LLM for High-Accuracy Document Recognition and Content Understanding in Seconds


Our Intelligent Character Recognition technology combines traditional OCR with advanced Large Language Models (LLM), capable of recognizing text in images or documents within seconds while deeply understanding semantic context. The system supports JPG, PNG, PDF, TIFF, and other common formats — whether scanned documents, smartphone photos, or multi-page PDF reports — efficiently processing and outputting structured text data.

Unlike traditional OCR that merely reads characters, our system uses LLM to further understand document semantics — automatically correcting recognition errors, filling in missing text, and inferring professional terminology from context. Simply upload an image or document and the system completes recognition, semantic analysis, and output automatically, dramatically reducing manual input and proofreading time. Whether for contract review in finance, quality inspection in manufacturing, or content digitization in media, OCR + LLM delivers significant workflow efficiency gains.

Automated Document Review

For the large volumes of contracts, invoices, and reports that enterprises handle daily, the system rapidly performs batch recognition and converts them to structured digital data. Combined with LLM semantic understanding, it automatically extracts key fields (such as amounts, dates, and signatory parties) and performs preliminary compliance checks, dramatically reducing manual review time and the risk of human error.

TV & Magazine Monitoring

Capture TV news tickers, program subtitles, advertising text, and magazine or newspaper image-text content in real time, automatically converting them to searchable text data. Combined with a keyword matching engine, quickly grasp brand exposure, competitor activity, and public sentiment trends — an essential tool for PR and marketing teams conducting media monitoring.

Smart Factory Data Recognition

Automatically recognize numerical values and text on production line machine dashboards and measurement device displays, instantly converting them to digital data and feeding them back to MES or ERP systems. Replacing manual transcription, this not only improves data timeliness and accuracy, but also enables automated production line quality monitoring and early warning through anomaly detection.

Table and Form Recognition

Precisely recognize complex table structures and handwritten form content, automatically preserving row-column relationships and outputting to Excel or CSV format. Whether financial statements, shipping documents, medical records, or surveys, the system correctly parses merged cells, multi-level headers, and other complex layouts, eliminating tedious manual reconstruction.

Multilingual Text Recognition

Supports recognition of Traditional Chinese, Simplified Chinese, English, Japanese, and other languages, and can handle mixed-language documents such as Chinese-English or Chinese-Japanese combinations. The system maintains high recognition accuracy for Chinese-specific traditional/simplified variants, rare characters, and Japanese kanji-kana mixed text — ideal for multinational enterprises and multilingual document processing.

OCR + LLM Semantic Understanding

Breaking through the limitations of traditional OCR that can only read characters one by one, combining large language models to deeply understand document semantics. The system can automatically summarize lengthy documents, answer questions about document content, annotate key information, and detect contradictions or anomalies. Upgrading document recognition from 'seeing text' to 'understanding content'.

FAQ


LargitData OCR is an intelligent recognition system combining traditional optical character recognition with large language models (LLM). It extracts text from images, PDFs, and media with high precision and applies semantic post-processing — achieving accuracy of 99% or higher in standard printed text environments.
Supported formats include image files (JPG, PNG, TIFF, BMP), documents (PDF, Word, Excel), and real-time text extraction from video streams for applications such as TV caption monitoring and broadcast content digitization.
Traditional OCR only recognizes text. With LLM integration, LargitData OCR understands the semantic meaning of recognized content — automatically classifying, extracting key information, and validating data accuracy — dramatically reducing manual post-processing time.
Accuracy reaches 99% or above in standard printed font environments. For complex backgrounds, handwritten text, and damaged documents, AI post-processing maintains accuracy above 95%.
Yes, LargitData OCR includes Intelligent Character Recognition (ICR) for handwriting, supporting Traditional Chinese and English. It is suitable for digitizing manually filled documents such as forms, questionnaires, and invoices.
Yes. In addition to cloud API services, LargitData OCR supports on-premise deployment within your enterprise environment, ensuring sensitive documents such as contracts, financial reports, and medical records never leave your network — meeting information security compliance requirements.
Primarily supported languages include Traditional Chinese, Simplified Chinese, English, Japanese, and numeric/special characters. Traditional Chinese is specially optimized for the Taiwan market, delivering higher accuracy for locally common fonts and terminology.
Yes. LargitData OCR provides a REST API interface that integrates easily with ERP systems, document management systems, hospital information systems (HIS), and more. Webhook support enables automated document processing workflows.
