Help with Text Correction

Why is text correction necessary?

The searchable text and titles in the Illinois Digital Newspaper Collections have been automatically generated using Optical Character Recognition software. They have not been manually reviewed or corrected.

Optical Character Recognition (OCR), is a process by which software reads a page image and translates it into a text file by recognizing the shapes of the letters.

OCR enables searching of large quantities of full-text data, but it is never 100% accurate. The level of accuracy depends on the print quality of the original issue, its condition at the time of microfilming, the level of detail captured by the microfilm scanner, and the quality of the OCR software. Issues with poor quality paper, small print, mixed fonts, multiple column layouts, or damaged pages may have poor OCR accuracy.

To look at the OCR text in the Illinois Digital Newspaper Collections , select the page/article and click the “Text of this page/Text of this article” link.

How to Correct Text

The text correction interface is accessed by clicking the “Correct this text” link when viewing section text. This interface is split into two parts: the right side shows the page images that make up the document, and the left side is used for editing the lines of text.

When you move your mouse over the page images in the right pane, the blocks making up the pages will highlight. You can scroll this view by dragging with the mouse, or zoom in/out using the buttons above the viewer. Clicking a highlighted block will select it and load a form for editing that block into the left pane.

Correct the text line by line. A red box is displayed in the right pane to help you determine what text should be included in the line. Once you have finished correcting text, click “Save”. The changes you make will take effect immediately. Alternatively, clicking the “Cancel” button will discard any unsaved changes you have made.

You can then make further corrections to the same block, move onto the next block by clicking the “Next” button, select another block in the right pane, or exit the text correction view by clicking the “Return to viewing mode” link. Clicking “Save & exit” instead of “Save” will save the changes and then return you to the normal viewing mode automatically.

Hint: Many web browsers include spell checking functionality and this can assist with your text correction by identifying misspelled words. If your web browser does not have this functionality, it’s likely there is a spell checking add-on available (see your web browser’s help for information on how to install add-ons).
