Title: Transforming the Information Landscape: Research Directions for Digital Libraries


1
Transforming the Information Landscape Research
Directions for Digital Libraries
Report of the NSF Workshop on Research Directions
for Digital Libraries Digital Library
Advance the Efficiency of Knowledge
Utilization National Library of China Sept. 6-8,
2004
  • Ronald L. Larsen
  • School of Information Sciences
  • University of Pittsburgh

Knowledge Lost in Information, NSF Award No.
IIS-0331314

Workshop Background
  • DLI over, DLI2 winding down
  • What is next?
  • Did we finish the job? Are we done?
  • What have we learned?
  • What constitutes DL research?
  • Does it influence other disciplines?
  • Should DL change from
  • Initiative to Program?

Workshop Goals
  • Seek transformative opportunities
  • Technically based
  • Broadly applicable and usable
  • Provide a foundation for post-DL NSF research
  • Based on vision
  • Building on past efforts
  • Providing multi-dimensional interoperability
  • Technical
  • Disciplinary
  • Temporal

5
Envision
  • Research critical to security, economy, health,
    and education
  • Ubiquitous Knowledge Environments
  • Imaginable futures
  • Beyond our grasp
  • Broadly applicable
  • Instantiable in micro scenarios
  • Amenable to a framework

6
The White PapersWhat participants came prepared
to discuss
  • Semantics applied to information
  • Development and integration of ontologies
  • Information stores
  • Digitized (images, spoken word)
  • Symbolic digital (text, links)
  • New forms (agents, services)
  • Managed Information Stores
  • Creation from information and semantics
  • Use for finding, creation, storage, usage
  • Infrastructure to support systems

7
Emerging U.S. Vision for DLs
  • Next generation digital libraries will be
  • A confluence of resources, technology and
    infrastructure
  • An intersection of national priorities and
    scientific goals
  • A common testbed for all computer and information
    science research (sub)disciplines
  • Federated resources serving individuals,
    institutions and governments simultaneously
  • A progression from information to knowledge

8
National priorities influence IT research agenda
Advances in Science and Engineering
Information Technology Research
Economic Prosperity and Vibrant Civil Society
National and Homeland Security
Digital Libraries form the Enabling Resources,
Technology Infrastructure
9
National priorities influence IT research agenda
  • Advances in Science and Engineering
  • Advance the frontiers of science and engineering
    research and education
  • Examples include those that collect, disseminate,
    and analyze observational or experimental data,
    or data from models or simulations
  • Economic Prosperity and Vibrant Civil Society
  • Human and socio-technical aspects of current and
    future distributed information
  • Topics include business, work, health,
    government, learning, and community, and their
    related policy implications.
  • National and Homeland Security
  • Robust Information Technology to protect critical
    infrastructures and support the understanding of
    threats to national security
  • Examples include collaborative knowledge
    environments, knowledge discovery, medical
    informatics, information extraction and fusion,
    cross-linguality, spoken language and imagery,
    social network analysis

Representational Model of Common Elements
Interaction
UnderstandingQueries
Store
User
Chunking
Massaging Results
11
Users
  • Cognitive Completion
  • MS spell-checker for facts and knowledge
  • Task and user context sensitive
  • Do what I mean
  • Find what I need
  • Be aware of what I know
  • Collaboration
  • Identifying the collegial context
  • Providing contextual guidance
  • Managing personal libraries
  • All that is seen and heard
  • Personal memory assistant

12
Stores
  • Capture Reading emerging content
  • Extract information
  • Transformations
  • Formats Tables, charts, text,
  • Languages Cross-lingual, multi-lingual, machine
    translation
  • Interpretation Machine recognition and
    understanding
  • Beyond rhetoric (e.g., bias detection)
  • Beyond words (e.g., intent identification)
  • Discovery Knowledge/information
  • Novelty, anomalies, causality, the unexpected

13
Interaction
  • Query Question-answering systems
  • Natural language processing
  • Context awareness
  • Chunking Cognitive patterns
  • User and process aggregation
  • Massaging Intelligent responses
  • Automated summarization and filtering
  • Multi-dimensional representations illustration,
    transformation, presentation

14
The ChargeDevelop a 10-year Challenge
  • Simple and unambiguous
  • Inspired by long term vision(s)
  • Users
  • Applications
  • Technology
  • Heritage
  • Reflecting NSF research mission

15
Technological Projections
  • Digital domination
  • Phone, TV, cameras,
  • Entertainment interaction
  • Personal terabyte, community petabytes
  • Ubiquitous computing
  • Widespread sensor networks
  • Readily available encryption
  • Quantity and diversity of information will still
    be overwhelming

16
Social Projections
  • Major unanticipated IT-related threat likely
  • Surveillance and information pollution spur
    revolt
  • Failure of technology to solve social problems
    increases technology-based, quick-fix solutions
    (!)
  • No solution in sight for flawed intellectual
    property regime
  • US risks falling behind more aggressive e-nations

17
Two Grand Challenges
  • Question-Answering
  • Factual Relationships Contextual
    Interpretive
    Inferential Discovery
  • Across media types (text and non-text)
  • Embedding Socio-Economic Values
  • Shared commons for creative work
  • Fair use, Equal access, Free speech, Patron
    privacy
  • Customer service, dependability, longevity
  • Protecting intellectual property

18
Research Program
  • Increase the scope and scale of information
    resources and services
  • Employ context at the individual, community, and
    societal levels
  • Develop algorithms and strategies for
    transforming data into actionable information
  • Demonstrate the integration of information spaces
    into everyday life
  • Improve availability, accessibility, and
    productivity

19
Infrastructure Program
  • Acquisition of new information resources
  • Effective access, spanning media type, mode, and
    language
  • Utilities to leverage humankinds knowledge
    resources
  • Assured stewardship over humanitys scholarly and
    cultural legacy
  • Efficient and accountable management of systems,
    services, and resources

20
Recommendations
  • 20M / year for new U.S. research
  • Search, context, extraction, ubiquity,
    productivity
  • 40M /year for sustaining evolving resources in
    the U.S.
  • Acquisition, access, usage, stewardship,
    management
  • Coordinate with Advanced Cyberinfrastructure
    Program
