Working with Archival Texts as Data – Post-OCR Error Correction with OpenRefine

Working with Archival Texts as Data –

Post-OCR Error Correction with OpenRefine

Digitization can provide far greater access to archival documents, but their discoverability via full text searches may be hampered by error-laden optical character recognition (OCR). Correcting them manually, however, is unrealistically time-consuming. In this workshop, we will use OpenRefine – a spreadsheet-like software – to accelerate the finding and correction of spelling errors introduced through the OCR process.

Time: 4:00 pm ET/ 1:00 PT (2 hours)

Date: April 13, 2022

Cost: Members $ 50.00, Non-Members: $ 75.00, Student Members / Precariously employed members: $ 25.00

Learning outcomes: By the end of the workshop, you will be able to 1) perform initial data analysis on OCR text output and 2) apply computational techniques to correct common OCR errors.
