  • Hello, My name is Laura and I'm here to tell you about linking semantic desktop data to the web of data I'll start by describing a bit the reasons behind it, and a bit of background
  • Transcript of "Knowledge management on the desktop"

    1. 1. Digital Enterprise Research Institute deri.ie Knowledge management on the desktop Laura Drǎgan, Stefan Decker© Copyright 2009 Digital Enterprise Research Institute. All rights reserved.
    2. 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. 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. 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

    7. 7. Differences and SimilaritiesDigital Enterprise Research Institute www.deri.ie  Architecture  Data representation  Evaluation 7
    8. 8. ArchitectureDigital Enterprise Research Institute www.deri.ie  Layered – modular – service oriented  Layers (fuzzy)  Data layer  Service layer  Presentation / Application layer 8
    9. 9. Data layerDigital Enterprise Research Institute www.deri.ie  Data-centric  Functions  Unlock desktop data from application repositories  Transform data from application specific formats 9
