    technology perspective.
  • Next generations of search systems.

    over carefully in order to find something.
  • Explore to investigate, study, or analyze
  • Prospect a place showing signs of containing a
    mineral deposit, a potential buyer or customer

4
History of Computing Processing
  • Centralized
  • Network
  • PC
  • Internet

5
History of Computing Data
  • Small volume mostly numbers.
  • Alphanumeric data.
  • Structured data rise of databases.
  • Distributed data sources.
  • Semi structured data documents
  • Unstructured sources of data --- WWW
  • Multimedia images, audio, video, sensors
  • Live data.

6
Cyberspace
  • The electronic medium of computer networks, in
    which online communication takes place.
  • Digital space connected by Internet.

7
Evolution of Cyberspace
  • Documents dominate
  • Multimedia appears
  • MP3
  • Images and video (Video on Demand)
  • Sensor networks, Ubiquitous computing
  • The Phone phenomenon

8
Search Inside
  • Many operations in computing are search based
  • IBM 1620 computer
  • Problem solving could be viewed as exhaustive
    search
  • Search is becoming backend
  • Goal is solving a problem

9
Several Stages in Search
  • Databases
  • Information Retrieval
  • Web Search
  • Directories
  • Crawlers
  • Page Rank
  • RSS

10
Data has been changing
11
Some changes in Cyberspace and Search
  • Spatio-temporal data is norm rather than an
    exception.
  • People are interested in insights. Different
    types of data is a means to the insights.
  • Exploration is the predominant mode of
    interaction rather than query.
  • Context and state are very important.

12
Information and Insight
Experiential Environments
Insight
Visualization
Search Engines
Current Databases
Information
Precise Alphanumeric Source (20th Century)
Imprecise Heterogeneous Sources (21st Century)
Decision implementers need information, Decision
makers require insights.
13
Data, Information, and Insight
  • What Which thing or which particular one of many
  • Who What or which person or persons
  • Where At or in what place
  • When At what time
  • How In what manner or way by what means
  • Why For what purpose, reason, or cause with
    what intention, justification, or motive

14
Insights require understanding Relationships
15
Information and Experience 1
  • Jay Stanley was born on Jan 29, 2002.
  • Now he is a cute curious boy.

16
Information and Experience 2
Mobile phones are now very common.
17

Experience
18
Results from some Search Engines
  • Showing results form some engines.
  • In many cases I use examples related to self so I
    can comment about the quality of results.
  • No exhaustive efforts today more an anecdotal
    account.

Web Search Technology is in its early Infancy.
Three stages in the evolution of the Web
  • Document Web Current Generation
  • Text documents dominate.
  • Multimedia Web Merger of Media and Internet
  • Images, audio, video also become first class
