Group A: Next Generation
Information Access Group

Mission Statement

    To develop the next generation of access to information:

    • By content
    • Across domains
    • For various kinds of data to facilitate knowledge discovery

1-Stop Information Shopping by Content

Access across all domains  (facilitated by API's)

    • Scientific
    • Humanities (music, art, social science)

In all languages and all forms of expression

E.g., Braille, sign language

Research Issues: Universal Data Access

Intuitive access

Web-based, distributed IR

Integration of multimedia/multimodal data types

Software architectures (API, experimental prototypes)

Cross-lingual

DB for XML

Indexing of new data types

Similarity queries

Weighting

Continuum of Correctness

Approximate answer (versus speed)

IR degree of confidence

NLP and Statistics

Incomplete and inconsistent information

New Query Types

Data mining on multimedia data

Data mining as database querying

Rule induction

Association rules

Universal Knowledge Operators
(Fundamental) Generalized Access Framework

Representations

Image-Continuous Media

Text

Numbers

Operations

Classification

Clustering

Temporal

Association rules

Rule induction

Integration of Knowledge Representation

NLP and IR (case based reasoning in the large)

Prior knowledge

Management of discovered knowledge

User-centered

Better content representations than "bag of words"

Needs / Enablers

Test Collections and Procedures Depository

Multidimensional, multimedia

Spatiotemporal, deductive, active

Data mining, distributed searching (But has to be done carefully!)

Leisure dbs, photo dbs (zoom angle)

SBIR + IDM coordination?

Software tools?
