In this paper we present the digital library assistant (DiLiA). The system aims at augmenting the search in digital libraries in several dimensions. In the project advanced information visualisation methods are developed for user controlled interactive search. The interaction model has been designed in a way that it is transparent to the user and easy to use. In addition, information extraction...

The NZDL aims to impose structure on anarchic and uncataloged repositories of information, providing information consumers with effective tools to locate and peruse what they need. Our goal is to produce an easy-to-use digital library system that runs on inexpensive computers at information providers’ own sites and offers an information service that information providers themselves maintain. Ne...

Digital libraries are large, organized, focused collections of information. The Greenstone software is intended to help people design and build such collections quickly and easily. Collections may be large—some comprise Gbytes of text; others include many millions of short documents. Additionally, far larger volumes of information may be associated with a collection—typically audio, image, and ...

Millions of dollars have been invested into the development of digital libraries. There are many unanswered questions regarding their evaluation, in particular, from users’ perspectives. This study intends to investigate users’ use, their criteria and their evaluation of the two selected digital libraries. Nineteen subjects were recruited to participate in the study. They were instructed to kee...

This chapter introduces the concept of usability and provides examples of how usability has been used in digital library evaluations. Usability is a user-centered evaluation and has a theoretical base in human-computer interaction. The most concise definition of usability is “fit for use.” The dimensions of usability may also include usefulness, usableness, ease of use, effectiveness, efficienc...

Many systems provide search and recommendation capabilities to scholars that search for scientific documents including research papers and dissertations. The appearance of search results may largely affect the system use. Traditional approaches provide textual formats for showing the results to users, whereas more recent approaches concentrate on other forms, e.g., on two dimensions. Moreover, ...

After an overview of theworldwidemathematical journals ecosystem, we summarise some of the hopes and fears raised by the digital environment. We then review the underlying principles and main features of some of the projects launched by Cellule MathDoc that aim at settling robust foundations and giving wider access to academic mathematical research journals. In turn, they could prefigure some b...

The goal of the VISION (Video Indexing for SearchIng Over Networks) project is to demonstrate the technology necessary for a comprehensive, on-line digital video library. We have developed automatic mechanisms to populate the library and provide content-based search and retrieval of video over computer networks. The salient feature of our approach is the integrated application of mature image o...

We report on the Gaussian file search system designed as part of the ChemXSeer digital library. Gaussian files are produced by the Gaussian software [4], a software package used for calculating molecular electronic structure and properties. The output files are semi-structured, allowing relatively easy access to the Gaussian attributes and metadata. Our system is currently capable of searching ...
