Tesseract is an optical character recognition (OCR) system. It is used to convert image documents into editable/searchable PDF or Word documents. It is a free, open-source software run through a Command-Line Interface (CLI). Tesseract is considered one of the most accurate open source OCR engines currently available and its development has been sponsored by Google since 2006.That being said, its capabilities can be more limited than commercial software like Adobe Acrobat Pro and ABBYY FineReader. However, because it is an open source software, anyone with programming knowledge can edit the code behind Tesseract and help it learn what you need to do. It can be used on Mac, Windows, and Linux machines.
How Tesseract analyzes documents:
- User inputs document title, desired title, and desired format into Tesseract
- Tesseract analyzes these images and creates a new, searchable document in the user's desired format
- Unlike other OCR software, you cannot scan something directly into Tesseract
Basic OCR Operations in Tesseract:
- Image format (JPG, TIF, PNG, etc.) to PDF, Microsoft Word
- New document appears in the same directory as initial document
- Run through your Command-Line Interface
With the resulting files being editable and searchable, researchers will be able to:
- Copy, paste, and edit passages of text within the new document
- Search the text in PDF readers or word processing programs
- Ingest the text into analysis programs like ATLAS.ti or NVivo
- Make information easier to find via the Internet by creating searchable documents
