  • 2. [Old] Challenges & MotivationsDigital Enterprise Research Institute www.deri.ie  Information overload Nelson (70s)  Data silos / application formats  Trusted information Nelson (70s)  Associative trails Bush (40s) – Engelbart (60s) 2
  • 3. memexDigital Enterprise Research Institute www.deri.ie  Vannevar Bush - “As we may think” - 1945! “... a device in which an individual stores all his books, records and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility” 3
  • 4. NLS and XanaduDigital Enterprise Research Institute www.deri.ie  Doug Engelbart & Ted Nelson  1960s and 1970s “better concept structures can be developed – structures that when mapped into a human’s mental structure will significantly improve his capability to comprehend and to find solutions within his complex problem situations.” 4
