A concept called shape is proposed to experimentally examine the development of users' mental representations of information spaces over time. Twenty five novice users are exposed to two differently designed news web sites over five sessions. The longitudinal impacts on users' comprehension, usability, and navigation are examined.

This paper reports on measurements of the NCSTRL digital library taken over a two-year period. We report the growth of the system along two dimensions: number of participating institutions and number of documents indexed by the system. We also report an aspect of reliability for this distributed digital library system.

Taiwan is renown for its great variety of butterflies. There are about 400 species, a number of which unique to Taiwan, over its 36,500 sq km land. Last year we built a comprehensive digital collection of Taiwan's butterflies to provide a modern research environment on butterflies for academic institutions, as well as an interactive butterfly educational environment for the general public. Our digital museum emphasizes on the ease to use, and provides a number of innovative features to help the user fully utilize the information provided by the system. The digital museum is accessible through the Web at http://digimuse.nmns.edu.tw.

Our prototype automatic title generation system inspired by statistical machine-translation approaches [1] treats the document title like a translation of the document. Titles can be generated without extracting words from the document. A large corpus of documents with human-assigned titles is required for training title "translation" models. On an f1 evaluation score our approach outperformed another approach based on Bayesian probability estimates [7].

To realize a wide range of applications (including digital libraries) on the Web, a more structured way of accessing the Web is required and such requirement can be facilitated by the use of XML standard. In this paper, we propose a general framework for reverse engineering (or re-engineering) the underlying structures i.e.,the DTD from a collection of similarly structured XML documents when they share some common but unknown DTDs. The essential data structures and algorithms for the DTD generation have been delveloped and experiments on real Web collections have been conducted to demonstrate their feasibilty. In addition, we also proposed a method ofimposing a constraint on the repetitiveness on the element in a DTD rule to further simplify the generated DTD without compromising their correctness.

We implemented a web server for acronym and abbreviation lookup, containing a collection of acronyms and their expansions gathered from a large number of web pages by a heuristic extraction process. Several different extraction algorithms were evaluated and compared. The corpus resulting from the best algorithm is comparable to a high-quality hand-crafted site, but has the potential to be much more inclusive as data from more web pages are processed.

The evaluation plan for the Alexandria Digital Earth Prototype (ADEPT) centers on two investigations: a study of classroom use of the system by faculty and students and lab-based usability studies. The classroom-based study is primarily an investigation of the digital library's impact on student learning, using multiple research methods. The five-year work plan includes investigations of the use of ADEPT in non-geography classes.

Digital library mediators allow interoperation between diverse information services. In this paper we describe a flexible and dynamic mediator infrastructure that allows mediators to be composed from a set of modules (``blades''). Each module implements a particular mediation function, such as protocol translation, query translation, or result merging. All the information used by the mediator, including the mediator logic itself, is represented by an RDF graph.We illustrate our approach using a mediation scenario involving a Dienst and a Z39.50 server, and we discuss the potential advantages and weaknesses of our framework.

A future with widespread access to large digital libraries of video is nearing reality. Anticipating this future, a great deal of research is focused on methods of browsing and retrieving digital video, developing algorithms for creating surrogates for video content, and creating interfaces that display result sets from multimedia queries. Research in these areas requires that each investigator acquire and digitize video for their studies since the multimedia information retrieval community does not yet have a standard collection of video to be used for research purposes. The primary goal of the Open Video Project is to create and maintain a shared digital video repository and test collection to meet these research needs.
