Digital Libraries --- Objectives

World Lit.: 24hr / 7day / from desktop Integrated “super” information systems: 5S: streams,

structures, spaces, scenarios, societies Ubiquitous, Higher Quality, Lower Cost Education, Knowledge Sharing, Discovery Disintermediation -> Collaboration Universities Reclaim Property Interactive Courseware, Student Works Scalable, Sustainable, Usable, Useful

DLs: Why of Global Interest? National projects can preserve antiquities and heritage:

cultural, historical, linguistic, scholarly Knowledge and information are essential to economic and

technological growth, education DL - a domain for international collaboration

– wherein all can contribute and benefit

– which leverages investment in networking

– which provides useful content on Internet & WWW

– which will tie nations and peoples together more strongly and through deeper understanding

Why of Interest in Computing? Next step in fields of DBMS, HT, IR, MM Efficiency requires advances in, e.g.,

– algorithms and data structures (ex., MPHF)– networking (ex., HTTP-NG)– OS (ex., support for streams)

Effectiveness requires advances in, e.g.,– AI (ex., multilingual texts, user adaptation)– HCI (ex., visualization, DLs embedded in activities)

CS Educ. can benefit; CS can aid Dist. Educ.

SMETE Library(from www.dlib.org)

Context: Global movement toward Digital Libraries (see April 1998 CACM)

NSF effort: Science, Mathematics, Engineering, and Technology Education Digital Library (focussed on undergraduates)– 3 workshops, yearly increasing funds / new calls

SMETE Library likely to operate as distributed federation, with separate parts for each key discipline, and to lead to a global effort

ENVISION

A User-Centered Database from the Computer Science Literature (1991-93)

Collected bib/typesetter data, converted to SGML Scanned thousands of page images MARIAN search engine - can be made available (also

applied to the Virginia Tech library catalog) used as part of a prototype object-based DL, with tailored visualization interface (L. Nowell dissertation)

Envision Results Window

CS -> CSTC -> CRIM

NSF and ACM Education Committee are funding a 2 year project “A Computer Science Teaching Center” - CSTC - http://www.cstc.org/~cstc/

College of NJ, U. Ill. Springfield, Virginia Tech Focus initially on labs, visualization, multimedia Multimedia part is also supported by a 2nd grant to

Virginia Tech and The George Washington University: http://www.cstc.org/~crim/

http://scholar.lib.vt.edu - solutions/statisticsMultilingual federated search: prototypeTemporary storage / archiving, aid - in setting

up an int’l service & archive

PetaPlex

Parallel computer / storage utility for scale of 1000 to 1,000,000 gigabytes (terabyte/petabyte)

Knowledge Systems Incorporated will supply VT-PetaPlex-1 with 2.5 terabytes, > 100 processors, high speed backbone connection

High-performance “superstore” available to help with NUDL

Relationship with publishers

Concern of faculty and students that still wish to publish books or journal articles, voiced: campus, Chronicle, NPR, Times

Solution: Approval Form gives students, faculty choices on access, when to change access condition; use IPR controls in DL

Solution: by case, work with publishers and publisher associations to increase access– AAP, AAUP– AAAS, ACM, ACS, Elsevier, ...

Some responses from publishers

ACM: need to acknowledge copyright Elsevier: need to acknowledge copyright IEEE-CS: need to acknowledge copyright ACS: wants right of first publication, but then can be

freely available U. Mich. Press (Colin Day): think seriously about

effect on market of monographs In general: restricting access to local campus will not

cause any problems

Future Work Work with publishers to increase level of access,

develop stds, ensure author education Interoperability tests among universities and with

publishers to provide integrated services Study with testbed that emerges, to improve information

retrieval, browsing, interface, and other types of user support

Evaluation, improving learning experience, spread to worldwide initiative, sustainable support and coordination

Education

Retain ABDs Improve writing (including 2nd language) Improve organization Improve presentation’s technical qualitySupport above in libraries, media centersSupport above “anytime, anywhere” Support faculty as well as students

Professional Societies

Like “writing across the curriculum”Besides writing: computing/communications,

information literacy, personal digital library management, tool use, research methods, collaboration, archiving/preservation

Data sets, communities of users of themClassification systems / browsing / searchingNRC’s “On becoming a researcher”

Interoperability IBM DL: donated equipment, powerful IPR (see TOIS,

D-Lib) - in use at Jena, Essen Z39.50: OCLC SiteSearch / VT tailored s/w

– university libraries w. catalogs of freely shared MARC/DC records pointing to archival copies

– via URNs: handles & PURLs Dienst / NCSTRL - www.ncstrl.org: CS depts., DARPA,

NSF, CNRI, Cornell - UVA is working on extensions for ETDs - Portugal is studying use for Europe

Accessibility

Interface design (simple, 3D, VR)Usability studiesGeneric multi-lingual supportSupport for those with disabilitiesHybrid collection (paper, MARC,

abstracts, full-text, multimedia)Disciplinary classifications, toolsVisualization of results, collection

SPIRES Visualization

Record all work with NDLTD, return to any prior situation, prepare bibliography

Powerful (multilingual, text, image, video) searching; browsing (with categories, in cluster hierarchies); using citation links; SDI

Supported collaboration across one’s field: help with literature review, sharing tools and data sets, applying others’ methods

Research Goals: User Aims

Research Goals: Testbed

Heterogeneous: Language, terminology Writing style, “structure” Subjects / topics Communities of use,

“scenarios”/services Types of related publications

and co-uses Cataloging, classification

“spaces” - info. viz.

Personalization Multimedia “streams” Variation in size: MARC

record, title + abstract, full-text, “container object”

“Societies”: dept., college, univ., state,, sports group, nation, language group, ...

CONCLUSIONS Digital libraries may provide powerful support for learners if

properly developed and supported by suitable, scalable, sustainable infrastructure.

CSTC and CRIM will help us explore how learning about computing can be enhanced by a large number of well-crafted modules that illustrate key concepts and can be “glued” together in a variety of fashions to suit local needs.

NDLTD will have a dramatic impact on graduate education if institutions participate, which is a “win-win situation”. NUDL will broaden this.
