Full text recognition & field-level recognition

In general, two types of recognition are possible: full text and field-level recognition. Full text recognition is used for document conversion and usually includes usage of OCR technology. Field-level recognition is used to extract particular data and includes usage of OCR, ICR and other technologies.

The following table shows the differences:

Specification Full text recognition Field-level recognition
Used for: Document conversion, books archiving Data capture / Data extraction
Document analysis: General document analysis, document analysis for invoices, document analysis for full-text indexing Manual blocks specification for field-level recognition
Recognition technologies: OCR with up to 99% accuracy OCR, ICR, OMR, Barcodes recognition with predefined data types and values range. 99.99% accurate
Verification: Recommended (for content reuse) Obligatory (as accuracy is a critical issue in most cases)
Synthesis: Used for document reconstruction Not used
Export format: Document files (RTF, DOC, PDF, etc.) Export to XML file or database
