Text retrieval from early printed books

Retrieving text from early printed books is particularly difficult because in these documents, the words are very close one to the other and, similarly to medieval manuscripts, there is a large use of ligatures and abbreviations.To address these problems, we propose a word indexing and retrieval technique that does not require word segmentation and is tolerant to errors in character segmentation. Two main principles characterize the approach. First, characters are identified in the pages and clustered with self-organizing map (SOM). During the retrieval, the similarity of characters is estimated considering the proximity of cluster centroids in the SOM space, rather than directly comparing the character images. Second, query words are matched with the indexed sequence of characters by means of a dynamic time warping (DTW)-based approach. The proposed technique integrates the SOM similarity and the information about the width of characters in the string matching process. The best path in the DTW array is identified considering the widths of matching words with respect to the query so as to deal with broken or touching symbols. The proposed method is tested on four copies of the Gutenberg Bibles.

A DIA oriented approach is suggested to effectively increase resolution and digitization speed, as well as to ensure document preservation during scanning and quality control [6,35].…”

They observe that curators should be informed about the needs of DL technology and drawbacks of lossy file formats like JPEG.…”

Document Analysis Systems VI

Abstract. Implications of technical demands made within digital libraries (DL's) for document image analysis systems are discussed. The state-of-the-art is summarized, including a digest of themes that emerged during the recent International Workshop on Document Image Analysis for Libraries. We attempt to specify, in considerable detail, the essential features of document analysis systems that can assist in: (a) the creation of DL's; (b) automatic indexing and retrieval of doc-images within DL's; (c) the presentation of doc-images to DL users; (d) navigation within and among doc-images in DL's; and (e) effective use of personal and interactive DL's.
