1. Context-enhanced Digital Library Services
Erich Neuhold, Claudia
Niederée, Avaré Stewart
Half Day (morning): 9:30 – 13:00, HS 2
Mediating between available information objects
and individual information needs is a central issue within the
functionality of a digital library. In the simplest case this is an
information request answered by a search engine based on an analysis of
information objects within the digital library's information
collection. However, neither the information access activity nor the
information objects within the collection are isolated entities. They
are both equipped with a multifaceted context. This tutorial analyzes
this context and discusses complementing approaches to make such
context explicit and to use it for refining the mediation process
within digital libraries.
2. Thesauri and Ontologies in Digital Libraries 1. Structure and Use in Knowledge-Based Assistance to Users
Half Day (morning): 9:30 – 13:00, HS 3
This introductory tutorial is intended for anyone concerned with subject access to digital libraries.
It provides a bridge by presenting methods of subject access as treated in an information studies program
for those coming to digital libraries from other fields. It will elucidate through examples the conceptual
and vocabulary problems users face when searching digital libraries. It will then show how a well-structured
thesaurus / ontology can be used as the knowledge base for an interface that can assist users with search
topic clarification (for example through browsing well-structured hierarchies and guided facet analysis)
and with finding good search terms (through query term mapping and query term expansion - synonyms and hierarchic
inclusion). It will touch on cross-database and cross-language searching as natural extensions of these functions.
It will also mention the use of more richly structured ontologies, including Semantic Web applications.
The tutorial will cover the thesaurus structure needed to support these functions: Concept-term relationships
for vocabulary control and synonym expansion, conceptual structure (semantic analysis, facets, and hierarchy)
for topic clarification and hierarchic query term expansion). It will introduce a few sample thesauri and some
thesaurus-supported digital libraries and Web sites to illustrate these principles.
3. Thesauri and Ontologies in Digital Libraries 2. Design, Evaluation, and Development
Half Day (afternoon): 14:30 – 18:00, HS 3
This tutorial is intended for people who have a
basic familiarity with the function and structure of thesauri and
ontologies. It will introduce criteria for the design and evaluation of
thesauri and ontologies and then deal with methods and tools for their
development: Locating sources; collecting concepts, terms. and
relationships to reuse existing knowledge; developing and refining
thesaurus/ontology structure; software and database structure for the
development and maintenance of thesauri and ontologies; collaborative
development of thesauri and ontologies; developing crosswalks /
mappings between thesauri/ontologies. In summing up, the tutorial will
address the question of the resources needed to develop and maintain a
thesaurus or ontology.
4. Building Digital Library Collections with Greenstone
Ian H. Witten , David Bainbridge
Half Day (morning): 9:30 – 13:00, HS 4
This tutorial will demonstrate how to build a
variety of different kinds of digital library collections with the
Greenstone digital library software, a comprehensive, open-source
system for constructing, presenting, and maintaining information
collections. Collections will be built from HTML documents; Word, PDF
and PostScript documents; images in various formats; MP3 and MIDI
audio; MARC records; and more. For each collection, various different
full-text search indexes and metadata-based browsers will be created.
Attendees who wish to are encouraged to bring their laptops, install
Greenstone from a CD-ROM that we will provide, along with various
sample files, and follow along with the demonstrations on their own
5. Practical Digital Library Interoperability Standards
Ian H. Witten , David Bainbridge
Half Day (afternoon): 14:30 – 18:00, HS 4
As the field of digital libraries matures and new
systems and standards develop, the ability to interoperate between
systems becomes paramount. This tutorial gives a practical introduction
to many recent standards and de facto standards for interoperability,
and illustrates them using open source digital library software -
including online demonstrations of interoperation issues and solutions.
Core standards that are discussed include Dublin Core, OAI-PMH, METS,
and MODS. We use interoperation between Greenstone and DSpace as a
motivating case study.
For those demonstrations that involve Greenstone, attendees who wish to
may bring their laptops, install Greenstone from a CD-ROM that we will
provide, along with various sample files, and follow along with the
demonstrations on their own machine.

6. Digital Libraries: An Overview and Formal Framework
Edward A. Fox, Marcos André Gonçalves
Full Day: 9:30 – 13:00 and 14:30 – 18:00, HS 7
This tutorial will provide a thorough and deep
overview and introduction to the DL field, introducing and building
upon a firm theoretical foundation (starting with "5S": Streams,
Structures, Spaces, Scenarios, Societies), giving careful definitions
and explanations of all the key parts of a "minimal digital library",
and expanding from that basis to cover key DL issues, illustrated with
a well-chosen set of case studies. Attendees will receive a first draft
copy of a 400+ page book under development by the co-presenters, with
tentative title "Foundations for Information Systems: Digital Libraries
and the 5S Framework", based in part on ideas explored in Dr.
