La implementación de esta solución trae una revolución en el archivado y la gestión de colecciones históricas. El sistema no solo digitaliza documentos, sino que también crea metadatos complejos que permiten una búsqueda y análisis rápidos de materiales históricos. El reconocimiento automático de información clave como fechas, nombres, lugares y eventos facilita significativamente el trabajo de investigación. La integración con sistemas de bases de datos modernos garantiza la sostenibilidad a largo plazo y la accesibilidad de los materiales digitalizados para futuras generaciones.
The core of the system consists of several interconnected AI modules that ensure complex processing of historical documents. The first module utilizes advanced image preprocessing techniques, including adaptive binarization and correction of geometric distortions. This is followed by specialized OCR with a neural network trained on historical texts, which achieves exceptional accuracy even on difficult-to-read documents. The system also contains a module for automatic detection and classification of document structures, which recognizes headings, paragraphs, notes, and other elements. The classification module uses a combination of image analysis and natural language processing to categorize documents according to content, period, and type. All processed information is stored in a scalable database with advanced search and filtering capabilities.
Extensive digitization project of the historical collection comprising more than 50,000 documents from the 16th to the 20th century. The system was deployed for automatic processing of diverse materials including manuscripts, prints, maps, and photographs. Thanks to advanced AI algorithms, significant acceleration of the digitization process was achieved while maintaining high accuracy. Automatic document classification enabled their effective categorization and the creation of a searchable database.

The system uses advanced neural networks specially trained to recognize historical scripts and languages. It is capable of processing various types of scripts including Gothic, Humanistic, and Neo-Gothic. It contains an extensive database of historical fonts and writing styles, which is continuously expanding. For each document type, the system automatically selects the most suitable OCR model. It can work with more than 20 historical languages including Latin, Old Czech, German, and Greek. In case of an unknown script type, the system can be additionally trained on new samples.
OCR accuracy for damaged documents depends on the extent and type of damage, but the system achieves an average success rate of 85-95% even with problematic materials. It utilizes a combination of several OCR engines and advanced image preprocessing techniques including adaptive binarization, noise removal, and reconstruction of missing parts. The system can compensate for faded text, stains, folds, and other common types of damage. For severely damaged documents, it offers the option of semi-automatic processing with human supervision.
Automatic document classification is performed in several phases. First, the system analyzes the visual characteristics of the document (layout, font type, graphic elements). It then performs content analysis using NLP (Natural Language Processing) to identify key topics, dates, and entities. Based on this information, the document is categorized into predefined categories. The system utilizes a hierarchical classification model that enables multi-level sorting according to various criteria (period of origin, document type, topic, language, etc.).
Basic hardware requirements include high-performance scanners with high resolution (at least 300 DPI) and specialized lighting for historical documents. Processing requires a server with a powerful GPU for AI computations (at least NVIDIA RTX 3080 or equivalent) and sufficient RAM (minimum 32 GB). Storage must be sized for the expected data volume with redundancy. Using SSDs for active data and tape libraries for archiving is recommended. The network infrastructure should support fast transfer of large data volumes.
The security of digitized documents is ensured by a multi-level protection system. All data is encrypted both during transmission and storage (AES-256). The system uses redundant storage with automatic backup in multiple locations. Access to documents is controlled by roles with multi-factor authentication. Automatic data integrity checks and checksum creation are performed regularly. For critical documents, it is possible to set special security policies, including logging of all accesses and changes.
The system supports a wide range of output formats suitable for various purposes. For archiving, the lossless high-resolution TIFF format is used. For common use, documents are available in PDF/A (archival standard), JPEG2000, and PNG formats. The text layer is stored in Unicode with XML/TEI support for structured documents. Metadata is exported in standardized formats such as METS, MODS, and Dublin Core. The system also allows generating previews in various resolutions and optimized versions for web browsing.
The staff onboarding process is divided into several phases and typically takes 2-3 weeks. Basic operation of the digitization and cataloging system can be mastered in 2-3 days of intensive training. Advanced features like classification scheme management and OCR optimization require an additional week of training. An extended two-week course is intended for system administrators. Training includes hands-on practice with real documents and solving typical problematic situations. The basic training is followed by a period of supervised work.
The system offers flexible integration options with commonly used archival and library systems. It supports standard protocols for data exchange (OAI-PMH, Z39.50, SRU/SRW) and common API interfaces (REST, SOAP). Metadata can be synchronized with existing catalogs and digital libraries. The system allows mapping of custom classification schemes to standard formats and taxonomies. For specific requirements, custom connectors and integration bridges can be developed.
Multilingual processing and historical spelling variations are handled using specialized language models and dictionaries. The system contains an extensive database of historical word variants and spelling forms for various languages and periods. It utilizes contextual analysis for correct interpretation of historical texts. For each document, the primary language and period can be specified, increasing the recognition accuracy. The system also supports automatic language detection and transcription into modern orthography.
The system provides comprehensive tools for post-processing digitized documents. It includes an editor for manual OCR text corrections with a visual comparison of the original and recognized text. It allows batch edits and the application of rules to fix common errors. It supports a versioning system that keeps track of all changes. For collaboration among multiple proofreaders, a workflow system is available with the ability to assign tasks and monitor work progress. Corrected texts can be automatically propagated to all output formats.
