Asilomar Grand 10-Yr Vision 1998
Far from this Personal differences
Much will remain unorganized, autonomous
The Information Utility Make it easy for
everyone to store, organize, access, and analyze
the majority of human information online.
Much more than access analysis collaboration
socialization
3
Emerging Environments
Distributed autonomous peers - access to each
others data/services thru (transitive)
interaction - offering search other data
services for individuals groups
4
Search Uncertainty

• User may have no knowledge of
• Systems actual cost (in work, time, , )
• Quality of results (wrt freshness, completeness,
  )
• Origin of results (systems original or brought
  in w/)
• System may have no knowledge of users
• True needs behind a request
• Financial capacity, patience
• Quality desires
• Risk averseness
• Content preferences

5
Emerging Environments
Querying/Searching for information should be
similar to buying material goods and services in
real life
6
Search/Query Optimization

• Multiple criteria
• Processing (work, time), result (freshness,
  completeness, interestingness), money,
• Market research
• For data availability, data quality, processing
  cost,
• Quality Control
• Learning of peers s and s
• Insurance contracts for quality/cost guarantees
• Negotiation
• Queries and their results are commodities
• Query answers and query operator executions are
  traded
• Deals are struck and contracts are signed for
  specific QoS
• Recursive trading possibilities (subcontracting)

7
Personalization

• All aspects of search/querying could be
  personalized
• Systems employ user models maintain evolving
  profiles of personalities (preferences, needs) of
  individuals groups
• Queries (user interfaces, sense of object
  similarity, )
• Info source (trust of peers, quality parameters,
  )
• Results (objects of interest, presentation, )
• Profile parts activated at various stages
• Query rewriting based on content preferences
• Feature-set selection for similarity testing
• Choice of information sources or optimization
  criteria
• Socialization, collaboration
• Privacy vs. personalization

8
Contextualization

• All aspects of search/querying could depend on
  the context
• Context may include the searcher
  (personalization), location, time, history, other
  users present,
• Context modeling, context detection,

Expensive processing Extensive results
Quicker answers Shorter result list
