The screen-shot below shows the “Language Editor” implementation of FineReader 10, witch is shipped with FineReader Engine 10.

Structure of a Recognition Language

Every recognition language has the following properties:

  • Name
  • Set of allowed characters:
    • alphabet
    • list of prefixes
    • list of suffixes
    • alphabet for subscripts
    • alphabet for superscript and
    • list of ignored characters.
    • Dictionaries are optional, so a language can have one, but recognition will also “work” without one.

Language Auto-Detection

  • ABBYY technologies are able to detect language of a document automatically.
  • The product chooses the best matching language from a group pre-defined group of languages.
  • This group can be set/edited by the user/developer.

FineReader Engine 11 has new capabilities to work with multi-language documents, more details here: OCR Language Auto-Detection
