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

24.03.2000

Digital Libraries

This leads to a combination of• Libraries• Museums• Archives• Corporate and private Information Stores

that are actively supported by

24.03.2000

Informing Organisms

supporting cultural heritage

• technology components

• information based

• simple and complex

• growing in functionality

• interoperating

• mobile

• intelligent

24.03.2000

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

24.03.2000

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

Information Retrieval, Filtering, Enrichment user driven, supporting team- and groupwork, integrative,

intelligent, imperative, and declarative

24.03.2000

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

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

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)

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

24.03.2000

Clearly Multidisciplinary

• Computer Science

• Embedded Systems Engineering

• Linguistics (multi-language, analysis-generation)

• Communication Science

• Library / Museum / Archive sciences

• Information Science

• Psychology (cognitive, social)

24.03.2000

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

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

24.03.2000

Example: TREVI

Personalized • information filtering• linking

• delivery for the News Domain

24.03.2000

Example: TREVI

24.03.2000

Example: TV-ONLINE

• personalized profiles• personalized rankings• collaborative filtering • recommendations• automatic generation of individual

schedules.

24.03.2000

Example: TV-ONLINE

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

24.03.2000

Example: cyber:gallery

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)

24.03.2000

Example: Videocube

24.03.2000

Example: Lyberworld

• information visualization at the user interface

• supporting analysis clustering, partitioning• supporting user information profiles

24.03.2000

Example: Lyberworld

24.03.2000

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
