These output formats will be discussed and assessed in a forthcoming Network Notes . 2 Potential uses of this format will be the subject of a future Network Notes . In short, the decision to run OCR on a document should be based on the projected use of the document. Provides a facsimile of the original. Not a true representation of original.
Processing can affect both text and format accuracy.
If uses that require machine-readability have been identified for the document, a second consideration is whether the material in question is conducive to the OCR process. Both OCR accuracy rate and the throughput rate for the entire process should be compared with the alternative, which is regeneration of the document by manually rekeying the text into the computer. High accuracy rates have proven perennially difficult to achieve for certain types of library material including catalogue cards, multi-language texts, and historical items with faded type or unusual fonts. These factors may include resolution, condition, accuracy, completeness and legibility. Book cradle-scanners ensure better image capture while preserving bindings.
