Star-fish: Starfields+Fisheye Visualization and its Application to Federated Digital Libraries
نویسندگان
چکیده
We present star-fish, a focus+context approach to visualizing federations of large repositories that is based on the notion of starfields and is enhanced by functionality that allows users to keep track of the context of objects of their interest. This is accomplished through successive refinements of starfield representations in which areas of interest are magnified whereas surrounding areas are minimized, in the way of fisheye views. The resulting interface also makes use of iconic representations in starfields for differing types of collections, as well as colored variants for representing the institutions that hold the collections. The approach has been implemented on top a federation of digital libraries enabled by the OAI-PMH protocol.

متن کاملDigital Object Abstraction Layer: A Middleware for Building Federated Digital Libraries
Federated digital libraries focus on the development of common services over multiple, heterogeneous digital repositories. To offer advanced services for federated digital libraries, there is a need to provide an abstract representation of digital objects stored within a specific repository, maintaining their semantics. In this paper a middleware for the development of federated digital librari...
متن کاملUnderstanding Collections and Their Implicit Structures through Information Visualization
This chapter discusses how various approaches to information visualization can be used to assist users in understanding large digital collections and discovering relationships among the entities involved explicitly or implicitly in their development including people, organizations, and documents. Our main postulate is that visualization schemes, such as fisheye views, starfield displays, or sel...
متن کاملIntegrating Bibliographical Data from Heterogeneous Digital Libraries
The integration of bibliographical data today is considered one of the most important tasks in the area of digital libraries. Various available sources of bibliographical information vary widely in terms of data representation and access interfaces. To overcome this heterogeneity during the last years attempts were made to apply methods developed for information system integration, like federat...
متن کاملInformation Visualizations of Electronic Documents: Usability and Reading Patterns
Erik Frøkjær and I have recently been investigating if information visualizations support reading of electronic documents. Reading of such documents is becoming increasingly widespread, for example in digital libraries and on the World Wide Web. However, readers experience various difficulties with electronic documents compared to paper: electronic documents take longer time to read, it is diff...
