We report on the results of our experiments on query evaluation in the presence of noisy data. In particular, an OCR generated database and its corresponding 99.8% correct version are used to process a set of queries to determine the effect the degraded version will have on retrieval. It is shown that with the set of scientific documents we use in our(More)
We report on the performance of the vector space model in the presence of OCR errors. We show that average precision and recall is not affected for our full text document collection when the OCR version is compared to its corresponding corrected set. We do see divergence though between the relevant document rankings of the OCR and corrected collections with(More)
This paper describes a new automatic spelling correction program to deal with OCR generated errors. The method used here is based on three principles: 1. Approximate string matching between the misspellings and the terms occuring in the database as opposed to the entire dictionary 2. Local information obtained from the individual documents 3. The use of a(More)
In this paper we describe experiments that investigate the effects of OCR errors on text categorization. In particular, we show that in our environment, OCR errors have no effect on categorization when we use a classifier based on the naive Bayes model. We also observe that dimensionality reduction techniques eliminate a large number of OCR errors and(More)
Over the last 15 years, the Information Science Research Institute (ISRI) at the University of Nevada, Las Vegas (UNLV) has conducted information access research in the presence of OCR errors. Our research has focused on issues associated with the construction of large document databases. In this paper, we will highlight our findings and detail our current(More)
MANICURE is a document processing system that provides integrated facilities for creating electronic forms of printed materials. In this paper the functionalties supported by MANICURE and their implementations are described. In particular, we provide information on specific modules dealing with automatic detection and correction of OCR errors and automatic(More)
