The OCR function generates text of images and documents without embedded text. Several features use this generated text such as:
•Productions (exporting a separate .txt file for each document)
•Predictive Analysis (Gist)
For the generated text to be available for keyword searching the data must be re-indexed to add the newly generated text files to the index.
To access the OCR functions:
•Right-click on the filter tree and select "OCR..."
•Right-click one or more selected documents and select "OCR..."
In the OCR dialog choose whether to overwrite existing OCR and click Run to start the OCR process. Always replace the OCR after redacting documents.
When data sets involve additional languages the OCR can be optimized to recognize those languages.
To monitor the progress go to the Process tab and select the View Jobs interface.
The "OCR" column in the Document List will indicate whether or not a document has OCR. The Document Browser will contain an OCR tab for all documents with OCR.
Any errors that occur when generating OCR/extracted text while in the Process View will be logged and can be viewed on the Exceptions tab after processing completes.
