1. Group A Next Generation Information Access Group

2. March 31, 1998NSF IDM 98, Group A2 Mission Statement To develop the next generation of access to information:  By content  Across domains  For various kinds of data to facilitate knowledge discovery

3. March 31, 1998NSF IDM 98, Group A3 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

4. March 31, 1998NSF IDM 98, Group A4 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

5. March 31, 1998NSF IDM 98, Group A5 Continuum of Correctness Approximate answer (versus speed) IR degree of confidence  NLP and Statistics Incomplete and inconsistent information

6. March 31, 1998NSF IDM 98, Group A6 New Query Types Data mining on multimedia data Data mining as database querying  Rule induction  Association rules

7. March 31, 1998NSF IDM 98, Group A7 Universal Knowledge Operators (Fundamental) Generalized Access Framework Representations  Image-Continuous Media  Text  Numbers Operations  Classification  Clustering  Temporal  Association rules  Rule induction

8. March 31, 1998NSF IDM 98, Group A8 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”

9. March 31, 1998NSF IDM 98, Group A9 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? NSF should advertise success stories
