Transcript and Presenter's Notes

Title: Large Scale Data Collections


1
Large Scale Data Collections
  • Provide requirements
  • Data sharing - data grids
  • Data publication - digital libraries
  • Data preservation - persistent archives
  • Emerging commonality of capabilities
  • Data management infrastructure - bits
  • Information management - semantic tags
  • Knowledge management - relationships

2
10-Year Vision
  • Integration of knowledge management technologies
  • Integration of information repositories into
    infrastructure
  • Integration of relationship repositories into
    infrastructure
  • Knowledge generation to shorten innovation cycle
  • Application of knowledge management
  • Consistency constraints between services
  • Federation of collections
  • Context definition - evidence-based relationships

3
Implications
  • Interactions with user communities is essential
  • Scientific, education, cultural history
    collections
  • Interactions between technology development
    communities
  • Semantic web, data grid, persistent archive, IR,
    data mining,
  • Scalability of infrastructure
  • Today have catalogs with 1 billion records,
    collections with gt1 PetaByte of data
  • Define a context for each person (300 million)

Group 1
  • Participants
  • Christina Borgman
  • Gregory Crane
  • Jim French
  • Jose Marie Griffiths
  • Judith Klavans
  • Carl Lagoze
  • Reagan Moore
  • Shiego Sugimoto
  • Norman Wiseman

5
Tasks
  • Identify disruptive and transformative
    technologies/opportunities for digital libraries
  • Who cares and Why
  • Where to place the stake in the ground -
    strategic
  • Identify long term compelling vision

6
Long Term Vision
  • Generation Information
  • Management of Intellectual Capital
  • Preservation Knowledge
  • Re-use Cultural History

7
Compelling Vision
  • Structure information from the perspective of an
    individuals context
  • Large scale information integration
  • Personalization of information content
  • Context based interpretation of information from
    ubiquitous resources
  • Pro-social communication campaigns with targeted
    information
  • Personal information technology
  • Interaction with knowledge stores
  • Natural interaction mechanisms, dialogue
    management for social presence

8
Compelling Vision
  • Wellness for life
  • Authoritative information to the right person at
    right time
  • Personal genome management, impact of personal
    habits on disease risk
  • Consistent access/extraction of knowledge
  • e-Learning, e-Science
  • Transform education by access to new forms of
    information and knowledge
  • Inquiry based learning, promotion of learning
    models
  • Technology impact on education analysis

9
Compelling Vision
  • Creation of virtual learning environments
  • Roman forum
  • Scientist lab
  • Institutional infrastructure
  • Cyberinfrastructure extension into academia
    through information and knowledge management
  • Extracting structured information
  • Inferences between relationship spaces to create
    new knowledge
  • Recognition of valid knowledge
  • Taming the knowledge frontier

10
Compelling Vision
  • Convergence of technologies for digital
    libraries, data grids, persistent archives.
  • Data, information, knowledge organization
  • Personal digital library federation
  • Eliminate information overload
  • Knowledge bases as commodities
  • Evidentiary based event relationships
  • Evidence based relationships
  • Authority generation
  • Digital government - knowledge-based governance
  • Digital divide, equity, intellectual property

11
Compelling Vision
  • Generate, manage, preserve, and apply knowledge
  • Stand on the shoulders of knowledge giants
  • Identifying knowledge from sensor-based
    communications
  • Spam filters
  • How to manage information in ubiquitous data

12
Four Major Topics
  • Ubiquitous access to personalized knowledge
  • Knowledge extraction from unstructured data
  • Natural communication of information
  • Transform education through inquiry based
    learning
  • Knowledge life cycle for generation, management,
    preservation, repurposing
  • Cyberinfrastructure extension into institutional
    infrastructure for digital library, data grid,
    persistent archive
  • Personal organization of knowledge

13
Scenarios
  • (1) Ubiquitous access to personalized knowledge
  • Access to all information, personalized for
    individual needs by place and time
  • (2) Knowledge extraction from unstructured data
  • Self-organizing information, knowledge generation
  • (3) Natural communication of information
  • Socialization of knowledge
  • (4) Transform education by inquiry based learning
  • (5) Knowledge life cycle
  • (6) Extension of cyber infrastructure
  • (7) Personal organization of knowledge

14
Big Story
  • 10-years in future, there will be a pervasive
    knowledge environment, accessed by all
  • (1) Pervasive information environment, users get
    information/knowledge at any place at any time
    for any context, identify opportunities for new
    knowledge
  • (2) More natural means of interacting with
    knowledge, immersion in concept space
  • Socialization of knowledge for public good,
    wellness for life
  • Inquiry based education, create, manage, and
    share personal digital library of knowledge
    spaces
  • (3) Highly curated resources as organizational
    framework for knowledge
  • (4) Cyberinfrastructure enabling preservation
    within institutions including sustainability

15
Scenario
  • Person drives into Chatham
  • Takes a picture, adds to a community collection
  • Annotates with history of site
  • Incorporates into genealogy
  • Points to related sites of ancestor homes
  • Maps to county information for current owner
  • Builds a knowledge space / personal digital
    library
  • Publishes knowledge space on web
  • Preserves as part of community knowledge space
  • Community knowledge space integrated into
    national cyberinfrastructure

16
CyberInfrastructure
  • NSF Directorate collaborations
  • National Virtual Observatory data grid /
    collections
  • Ocean Sciences data grid / digital library
  • National Science Digital Library - educational
  • ITR - GEON, SEEK, SCEC, GriPhyN data grids
  • NPACI data intensive computing
  • DL Research activities
  • Synthesis of technologies to build the
    cyberinfrastructure
