Digital Libraries
All kinds of data stores that• handle multimedia information (content)• describe the information (metadata)• place the human in the center
– know and support the human player• are available at any time and at any place• are connectable to other user centered
applications

Digital Libraries
This leads to a combination of• Libraries• Museums• Archives• Corporate and private Information Stores
that are actively supported by

Informing Organisms
supporting cultural heritage
• technology components
• information based
• simple and complex
• growing in functionality
• interoperating
• mobile
• intelligent

The Issues:
A lot exists and goes on in• research (components)• advanced demonstrators (just working)• advanced prototypes/pre-products (non
scaling)• products
but more of it is needed in the Internet domain (i.e. global village). We have
• isolated solutions• simple solutions• technology driven solutions

Information and Knowledge
Databases (object relational, objects oriented, document
oriented, multimedia, active, real-time)
Information Representation and Description
Schemes (structured, semi-structured, unstructured,
Meta-Data, QoS parameters)
Information Content Analysis (text (linguistics), voice
(speech), sound, image, video, sensor data, sequenced
data)
Information Retrieval, Filtering, Enrichment user driven, supporting team- and groupwork, integrative,
intelligent, imperative, and declarative

Roles to Support (I)
User supporting issues: author, theme, content, presentation, reader / usage
Authoring Tools• multimedia, activity-oriented, supporting
group- and teamwork• acquisition / authoring new and legacy material
Information and Knowledge Handling Tools• indexing, extraction, structuring• classification, abstraction• separation / integration• distributing, storing
Erich J. Neuhold - [email protected] ©2000 GMD-IPSI
24.03.2000
Roles to Support (II)
Filtering & IR Tools• searching, exploration• navigation, inspection• evaluation
Enrichment & Adaptation Tools• user oriented• usage oriented• situation oriented• device oriented
Erich J. Neuhold - [email protected] ©2000 GMD-IPSI
24.03.2000
Roles to Support (III)
Presentation Tools• at different granularity levels
– documents, pages, modules – content and meta data semantics– manipulation and navigation
• for different application contexts (travel, settlement)
• for different activities, tasks, and workflows (creating, filtering, using, learning)
Erich J. Neuhold - [email protected] ©2000 GMD-IPSI
24.03.2000
Roles to Support (IV)
Usage Tools• documents and document manipulation• guidance to the answer• evaluation of solution • personalized memory• personalized information pipelining• communication, distribution, and mobility

Clearly Multidisciplinary
• Computer Science
• Embedded Systems Engineering
• Linguistics (multi-language, analysis-generation)
• Communication Science
• Library / Museum / Archive sciences
• Information Science
• Psychology (cognitive, social)

Needed for DL (I)
Basic research is needed (PITAC report)• separate topics (focused projects)• integrated topics (large projects)
Demonstrators / pilots are needed• integrated but focused (what will be
shown!)• proof of concept
Erich J. Neuhold - [email protected] ©2000 GMD-IPSI
24.03.2000
Needs for DL (II)
Sustainable proto-products are needed• open system approach, but still focused• have to scale somewhat
Products are needed• integrated but application driven /
exploitable• have to scale• have to be robust /reliable / serviceable
etc.• ready for start-up financing
Erich J. Neuhold - [email protected] ©2000 GMD-IPSI

Example: TREVI
Personalized • information filtering• linking
• delivery for the News Domain
Erich J. Neuhold - [email protected] ©2000 GMD-IPSI
24.03.2000
Example: TV-ONLINE
• personalized profiles• personalized rankings• collaborative filtering • recommendations• automatic generation of individual
schedules.
Erich J. Neuhold - [email protected] ©2000 GMD-IPSI
24.03.2000
Example: cyber:gallery
• exhibiting and selling art on the Internet• applying virtual reality paradigms• supporting searching and navigation• supporting personalized
galleries/museums and guided tours
Erich J. Neuhold - [email protected] ©2000 GMD-IPSI
24.03.2000
Example: Videocube
• visualization of scenes and camera movement in videostreams
• access to structure and content• direct manipulation of meta data and data
(technical and semantic levels)
Erich J. Neuhold - [email protected] ©2000 GMD-IPSI
24.03.2000
Example: Lyberworld
• information visualization at the user interface
• supporting analysis clustering, partitioning• supporting user information profiles

Conclusion
• come up with focused but integrated solutions
• advanced research and development of technologies using informing organisms
• pre-products and products will naturally follow those results
