The traditional methods based on the character recognition technique can be partly applied to this issue. However, these methods are not always successful for the cataloging cards, specified by different layout structures and various description rules. This paper proposes an experimental methodto extract and classify the data items automatically from cataloging cards.Our basic idea for the recognition strategy is to utilize various kinds of knowledge stepwisely on the basis of the generation/verification process of object hypotheses: in our approach, the knowledge such as layout information of card structures, relatonship information among cataloging items, and property imformation of data items is effectual.}, pages = {821--827}, title = {A stepwise recognition method of library cataloging cards on the basis of various kinds of knowledge}, year = {1991} }
