    Abstract
    Reports on experiments with retrieval from OCR-generated text using systems based on standard models of retrieval. Shows that average precision and recall is not affected by OCR errors across systems for several collections. Both the actual and the simulation experiments include full text and abstract length documents. The ranking and feedback methods associated with the retrieval models are generally not robust enough to deal with OCR errors. OCR errors and garbage strings generated from the mistranslation of graphic objects increase the size of the index significantly. Describes the problems of applying OCR text within an information retrieval environment and offers solutions
