Abstract: This paper proposes a novel system for information retrieval over a set of scanned documents in the Czech language. The documents are in the form of raster images and thus they are first converted into the text form by optical character recognition (OCR). Then OCR errors are corrected and the corrected texts are indexed and stored into a fulltext database. The database provides a possibility of searching over these documents. This paper describes all components of the above mentioned system with a particular focus on the proposed OCR correction method. We experimentally show that the proposed approach is efficient, because it corrects a significant number of errors. We also create a small Czech corpus to evaluate OCR error correction methods which represent another contribution of this paper.
