Comprehensive
Personalized Information Access in an Educational Digital Library
Peter Brusilovsky, Rosta Farzan,
Jaewook Ahn
|
|
Abstract: This paper explores two ways to help students locate most
relevant resources in educational digital libraries. One is a more
comprehensive access to educational resources through several ways of
information access including browsing and information visualization. Another
is personalized information access through social navigation support. The
paper presents the details of the Knowledge Sea III system for comprehensive
personalized access to educational resources and presented results of a
classroom study. The study delivered a convincing argument for the importance
of providing several ways of information showing that only about 10% of all
resource accesses were made through the traditional search interface. We have
also collected some good evidence in favor of the social navigation support.

A
New Framework for Building Digital Library Collections
George
Buchanan, David Bainbridge, Katherine Don, Ian H. Witten
|
|
Abstract: This paper introduces a new framework for building
digital library collections and contrasts it with existing systems. It
describes a significant new step in the development of a widely-used
open-source digital library system, Greenstone, which has evolved over many
years. It is supported by a fresh implementation, which forced us to rethink
the entire design rather than making incremental improvements. The redesign
capitalizes on the best ideas from the existing system, which have been
refined and developed to open new avenues through which digital librarians
can tailor their collections. We demonstrate its flexibility by showing how digital
library collections can be extended and altered to satisfy new requirements.

HiBO: A System
for Automatically Organizing Bookmarks
Pavlos
Kokosis, Vlassis Krikos, Sofia Stamou, Dimitris Christodoulakis
|
|
Abstract: In this paper, we introduce the HiBO bookmark
management system. HiBO aims at extending the populated personal repositories
(aka bookmarks) by automatically organizing their contents into topics,
through the use of a built-in subject hierarchy. HiBO offers customized
personalized services, such as the meaningful grouping and ordering of
bookmarks within the hierarchy's topics in terms of the bookmarks' conceptual
similarity to each other. HiBO also provides a framework that allows the user
to customize and assist the categorization process.

A
Generic Alerting Service for Digital Libraries
George
Buchanan, Annika Hinze
|
|
Abstract: Users of modern digital libraries (DLs) can keep
themselves up-to-date by searching and browsing their favorite collections,
or more conveniently by resorting to an alerting service. The alerting
service notifies its clients about new or changed documents. So far, no
sophisticated service has been proposed that covers heterogeneous and
distributed collections and is integrated with the digital library software.
|
|
This paper analyses the conceptual
requirements of this much-sought after service for digital libraries. We
demonstrate that the diffing concepts of digital libraries and its underlying
technical design has extensive influence (a) the expectations, needs and
interests of users regarding an alerting service, and (b) on the technical
possibilities of the implementation of the service.
|
|
Our findings will show that the range of
issues surrounding alerting services for digital libraries, their design and
use is greater than one may anticipate. We also show that, conversely, the
requirements for an alerting service have considerable impact on the concepts
of DL design. Our findings should be of interest for librarians as well as
system designers. We highlight and discuss the far-reaching implications for
the design of, and interaction with, libraries. This paper discusses on the
lessons learned from building such a distributed alerting service. We present
our prototype implementation as a proof-of-concept for an alerting service
for open DL software

Detecting
and Supporting Known Item Queries in online public access catalogs
Min-Yen Kan , Danny C. C. Poo
|
|
Abstract: When users seek to find specific resources in a digital
library, they often use the library catalog to locate them. These catalog
queries are defined as known item queries. As known item queries search for
specific resources, it is important to manage them differently from other
search types, such as area searches. We study how to identify known item
queries in the context of a large academic institution's online public access
catalog (OPAC). We also examine how to recognize when a known item query has
retrieved the item in question. Our approach combines techniques in machine
learning, language modeling and machine translation evaluation metrics to
build a classifier capable of distinguishing known item queries with an
accuracy of 72% and correctly classifies titles for whether they are the
known item sought with an accuracy of 86%. To our knowledge, this is the
first report of such work, which has the potential to streamline the user
interface of both OPACs and digital libraries in support of known item
searches.

Digital
Libraries support for the user's ‘Information Journey'
Adams, A.
Blandford
|
|
Abstract: The temporal elements of users' information
requirements are a continually confounding aspect of digital library design.
No sooner have users' needs been identified and supported than they change.
This paper evaluates the changing information requirements of users through
their ‘information journey' in two different domains (health and academia).
In-depth analysis of findings from interviews, focus groups and observations
of 150 users have identified three stages to this journey: information
initiation, facilitation (or gathering) and interpretation. The study shows
that, although digital libraries are supporting aspects of users' information
facilitation, there are still requirements for them to better support users'
overall information work in context. Users are poorly supported in the
initiation phase, as they recognize their information needs, especially with
regard to resource awareness; in this context, interactive press-alerts are
discussed. Some users (especially clinicians and patients) also required
support in the interpretation of information, both satisfying themselves that
the information is trustwortA Usability Evaluation Study of a Digital Library Self-Archiving
Service
Lena Veiga e Silva, Alberto H. F.
Laender, Marcos Andre Goncalves
|
|
Abstract: In this paper, we present the design, implementation,
and evaluation of a self-archiving service for the Brazilian Digital Library
of Computing (BDBComp). We focus on design decisions given the specific
context of the Brazilian CS community, the implementation details that follow
those decisions, and the evaluation of the implemented features. For evaluation,
we conducted an extensive usability experiment with several potential users,
including graduate students, professors, and archivists/librarians. The
results of that study and their implications for similar services are
described and analyzed, following sound statistical principles. Finally, a
comprehensive comparison of the features of ours and similar services is also
performed.

In
the Company of Readers: The DL Book as “ Practiced Place ”
Nancy
Kaplan, Yoram Chisik
|
|
Abstract: In this article we describe a system for annotating
digital books in a digital library for young adult readers and discuss a
first field test of the system with a small group of young adults together
with their families and a few friends. We argue that most studies of digital
libraries and their patrons' needs or desires look at adult users pursuing
work-related goals such as collaborative writing task encountered in college
or in professional work places. Most studies also examine the problems and
issues of research libraries rather than public libraries. Yet children who
are growing up digital may not only have different and heretofore
unrecognized needs but also may have insights into the needs future library
patrons may have. And public libraries, which support a broader public's
reading habits, may also need different kinds of tools for their patrons.
Because we are working with younger readers, we have focused on supporting
active reading but in the context of reading for pleasure. Our results show
that the digital library book for young adults can become a "practiced
place," by which we mean a site of shared, constructed meaning through
the traces that individuals' reading and writing create.

Using
Concept Maps in Digital Libraries as a Cross-Language Resource Discovery Tool
Ryan
Richardson, Edward A. Fox
|
|
Abstract: The concept map, first suggested by Joseph Novak, has
been extensively studied as a way for learners to increase understanding. We
are automatically generating and translating concept maps from electronic
theses and dissertations, for both English and Spanish, as a
DL aid to discovery and summarization.

A Multi-Timeline
Interface for Historical Newspapers
Robert B.
Allen
|
|
Abstract: Events may be are best understood in the context of other
events. Because of the temporal ordering, we can call a set of related events
a timeline. Even such timelines are best understood in the context of other
timelines. To facilitate the exploration of a collection of timelines and
events, a visualization tool has been developed that structures the user's
browsing. In this model, each event is accompanied by a text description and
links to related resources. In particular, this system can provide a browsing
interface of digitized historical newspapers.

To
Grow in Wisdom: Vannevar Bush, Information Overload, and the Life of Leisure
David M.
Levy
|
|
Abstract: It has been nearly sixty years since Vannevar Bush's
essay, “As We May Think,” was first published in The Atlantic Monthly, an
article that foreshadowed and possibly invented hypertext. While much has
been written about this seminal piece, little has been said about the
argument Bush presented to justify the creation of the memex, his proposed
personal information device. This paper revisits the article in light of
current technological and social trends. It notes that Bush's argument
centered around the problem of information overload and observes that in the
intervening years, despite massive technological innovation, the problem has
only become more extreme. It goes on to argue that today's manifestation of
information overload will require not just better management of information
but the creation of space and time for thinking and reflection, an objective
that is consonant with Bush's original aims.

Toward
a Metadata Standard for Digitized Historical Newspapers
Ray L. Murray
|
|
Abstract: This paper is a case study of metadata development in
the early stages of the National Digital Newspaper Program, a twenty-year
digital initiative to expand access to historical newspapers in support of
research and education. Some of the issues involved in newspaper metadata are
examined, and a new XML-based standard is described that is suited to the
large volume of data, while remaining flexible into the future.
