An unusual alliance called the ARCHway Project is developing an Edition Production Technology (EPT), a technological infrastructure for collaborative research, teaching, and learning between computer scientists and specialists in Old English. Our goal is to identify and solve problems of mutual importance in building image-based electronic editions of(More)
In recent years it has been argued that when XML encodings become complex, DOM trees are no longer adequate for query processing. Alternative representations of XML documents, such as multi-colored trees [7] have been proposed as a replacement for DOM trees for complex markup. In this paper we consider the use of Generalized Ordered-Descendant Directed(More)
Image-based electronic editions enable researchers to view and study in an electronic environment historical manuscript images intricately linked to edition, transcript, glossary and apparatus files. Building image-based electronic editions poses a two-fold challenge. For humanities scholars, it is important to be able to use image and text to successfully(More)
Concurrent markup hierarchies appear often in document-centric XML documents, as a result of different XML elements having overlapping scopes. They require significantly different approach to management and maintenance. Management of XML documents composed of concurrent markup has been mostly studied by the document processing community and has attracted(More)
The process of creation of document-centric XML documents often starts with a prepared textual content, into which the editor introduces markup. In such situations, intermediate XML is almost never valid with respect to the DTD/Schema used for the encoding. At the same time, it is important to ensure that at each moment of time, the editor is working with(More)
The problem of overlapping markup hierarchies, first mentioned in the context of SGML, often occurs in XML text encoding applications for humanities. Previous solutions to the problem rely on manual maintenance of the markup and address only the problem of representing overlapping features in XML, leaving the issues of automated maintenance and querying(More)
The process of authoring document-centric XML documents in humanities disciplines is very different from the approach espoused by the standard XML editing software with the data-centric view of XML. Where data-centric XML is generated by first describing a tree structure of the encoding and then providing the content for the leaf elements, document-centric(More)
One of most challenging problems in image processing is edge-preserving noise removal, because edges deliver most important information to the human visual system. The article is concerned with eÆcient numerical techniques for edge-preserving noise removal, solving nonlinear partial di erential equations. A new minimum-biased anisotropic di usion (MinBAD)(More)
