these two are in tension—data compression saves space, but at the expense of added access time; and indexing methods provide fast access, but usually at the expense of considerable amounts of additional storage space. Indeed, a complete index to a large body of text can be larger than the text itself—after all, it might store the location of every word in the text. The prospect of digital libra...

This paper presents the Indiana Ontology for modeling the knowledge about Mount Bego’s rock art and its exploitation in the IndianaMAS project. Although many projects use ontologies for semantic processing of cultural heritage digital objects, we are not aware of such ontologies in the rock art domain. Also, the Indiana Ontology is fully and seamlessly integrated with the IndianaMAS framework c...

The paper presents a software product developed in University comparable with other industrial products. The digital motion control development shell solves the hard real-time constraints imposed by the AC drive control applications. It was developed because of lack of integrated software tools for TMS320C3Cx family. The main advantages of the shell proposed are: high level programming, integra...

Interactive visualizations for exploring and retrieval have not yet become an integral part of digital libraries and information retrieval systems. We have integrated a set of interactive graphics in a real world social science digital library. These visualizations support the exploration of search queries, results and authors, can filter search results, show trends in the database and can supp...

DIGMAP is a digital library specialized in searching and browsing services for old maps and related resources. The service reuses metadata from national libraries and other relevant third party metadata sources, providing added value services by aggregating all the data in comprehensive collections, browsing indexes and search functions. The services are based in a set of specialized tools, com...

Automatic extraction of meta-data from collections of scanned documents (books and journals) is a useful task in order to increase the accessibility of these digital collections. In order to improve the extraction of meta-data, the classification of the page layout into a set of pre-defined classes can be helpful. In this paper we describe a method for classifying document images on the basis o...

This paper examines EASY, a two-year document delivery pilot project run jointly by Ingenta and Lancaster University. The main aim of the project is to test the feasibility of satisfying inter-library loan (ILL) requests directly from publishers’ digital files. These requests would otherwise have been satisfied by either photocopying or scanning by the supplying library and sent either to the r...
