Image Collections: Issues
Artists as information users
Fine Artists: producing artArt Historians: studying art
Fine Artists and Art Historians
Information needs:
A strong need to access information in several formats and several languages.
Sometimes they need to find objects and images similar to one they have already found.
Fine Artists and Art Historians
Information seeking:
Tend to search information by themselves.
Tend to browse and explore image collections without any specific idea of their information needs.
They tend to make extensive use of images in digital format.
Fine Artists and Art Historians
Information seeking:
When they know the specific work of art they are looking for, the main criteria used to search for images are text-based attributes, such as:
Title
Author
Period
Country of origin
Type of art object
Fine Artists and Art Historians
Information use:The relevance criteria they generally use to assess the relevance of visual materials are:
TopicalityImage qualityImage accessibilityImage noveltyImage suggestiveness
Image Collections: Issues
Design of new system features:
Browsing several images at a time
Exploring diverse collections at a time
Adaptive search strategies:
Concept-based search (ofness & aboutness)
Content-based search (bolbworlds: texture, shape & color)
Image Collections: Issues
Design of new standards and guidelines for image classification/indexing for digital collections.
Examples: CDWA: Categories for the Descriptions of Works of ArtVRA: Core Categories for Visual ArtBest Practice Guidelines for Digital Collections at UMD
(See PDF file)
Image Collections: IssuesDesign of new standard vocabularies, authorities, and term lists used for classifying works of art.
Examples: Library of Congress Subject Headings (LCSH)Art and Architecture Thesaurus (AAT)ICONCLASSUnion List of Artist Names (ULAN)Thesaurus of Geographic Names (TGN)LC Thesaurus for Graphic Materials I (TGM I)Others
Digital Repository: Example
Dspace:
An open-source digital archiving system designed by MIT Libraries and Hewlett Packard to capture, manage, and share research in digital formats.
Over 200 organizations have adopted Dspace as the basic architecture to develop their institutional repositories.

Basic Concepts
Digital Library:A collection of information, sources, and services in digital format, organized for use, and maintained by a public body, an institution, or a private individual.
Digital Libraries: Examples
ICDL
MALACH
PDLib
ICDL Demo
ICDL: International Children Digital Library
HCILab at the UMD
KidsTeam: a design methodology in which children of diverse backgrounds participate as design partners

ICDL Research Areas
How do children from diverse cultures search books:
In print format?in digital format?
How do children interact with digital content?
How do children build communities of digital library users across cultures?
ICDL Research Areas
How do children learn when searching and interacting with information in digital environments?
What are the personal information seeking patterns of children, as opposed to those identified for imposed information seeking?
How do children select and evaluate information?

MALACH Project Research
Funcionality:How to increase the performance of speech-recognition algorithms?
How to integrate cross-lingual retrieval algorithms?
Usability: How do users search and interact with digital video environments?
What kind of user interface better supports information discovery and exploration?
PDLib Project
PDLib: Portable Digital Library
An open source DL architecture where users can store all kinds of documents, and then retrieve them from desktop or mobile devices.

PDLib: Client/Server Architecture
PDLib Project Basic features:
Store your own documentsShare documents with other usersFeed your library through Internet searchesSearch documents:
with metadata attributesusing full textwithin multiple collections
Retrieve your documents anytime, anywhere, from your cell phone or PDA
PDLib Research AreasFuncionality:
How to increase the performance of full-text search algorithms? How to integrate cross-lingual retrieval algorithms?
Usability: How do PDLib users search and interact with information in digital environments?Is it possible to develop an audio-based interface for mobile devices?
