Too much information

Too Much Information

  • Then

    • “..there is increased evidence that we are being bogged down today as specialization extends”

    • “publication has extended far beyond our present ability to make real use of the record”

  • Now

    • In July 2000 more than 2 billion pages[1]

      • 4 billion estimated in 2001[1]

    • In 2002 over 9,040,000 Web Sites[2]

  • Sizing the Internet, Cyveillance White Paper Prepared by Brian H. Murray, Cyveillance, Inc.

  • OCLC: Online Computer Library Center


Creating a record photography

Creating a Record: Photography

  • Then

    • Faster, dry development

    • Smaller cameras

    • Reduce the size of the image without loss of quality - microfilm

  • Now

    • Polaroid Cameras

    • Digital Cameras

    • Electronic imaging a vast improvement over microfilm[1,2]

Creating a record written

Creating a Record:Written

  • Then

    • Synthesize speech – Voder

    • Record speech – Vocoder, Stenotype

    • Early voice recognition

    • Early character recognition - adding

  • Now

    • Voice and Text Recognition Software[1]

    • Philips 9450 VC Pocket Memo[2]

  • ART: Speech and Handwriting Interfaces for Mobil Devices

  • Phillips: 9450 VC Pocket Memo


Advanced mathematics

Advanced Mathematics

  • Then

    • Some machines to solve differential and integral equations

    • Predicted a machine able to reason with mathematical data

  • Now

    • Handheld calculators to solve differential and integral equations

    • IBM’s Blue Gene/Lite capable of 360 teraflops – trillions of calculations per second used to study interactions between atmospheric chemistry and pollution[1]

Information selection

Information Selection

  • Then

    • Simple Selection (Card Reader)

      • Examines each piece in turn

    • Problems indexing

  • Now

    • Existing web search techniques

      • Content/Link analysis


Information selection1

Information Selection

  • Then

    • Conventional Indexing is Inconvenient

    • The Memex

      • Large Storage

      • Easy retrieval

  • Now

    • Conventional Indexing Made Easier

    • The Personal PC

      • Dell’s Base Model comes with an 80GB hard drive [1]

1. Dell: Dimension Desktops


Associative indexing

Associative Indexing

  • Then

    • Memex documents linked via code word and photocell dots

    • Memex links are easily created and traversed

  • Now

    • HTML anchors link web content together

    • Able to navigate forwards and backwards through links (with help of crawler)


Beyond the memex

Beyond the Memex

  • Then

    • Information observed/recorded via senses (mechanical)

  • Now

    • Able to convert thought to mechanical output [1]

    • Not so far off from being able to observe, record, and access information simply by thinking about it
