  • Bild ändern?
  • Und statt Offering / Selecting/ Obtaining würde ich "Provision/Access" schreiben Und bei Re-Purposing ist man auch schon wieder so sehr im e-Learning-Bereich aber ich weiss auch nix gutes statt "Überarbeiten"
  • Evtl. das mit dem trusted noch etwas abschwächen (das hatte ich hier schon sehr hart formuliert)
  • Ich weiß nicht, ob man das hier aufnehmen muss in dem Umfang. Am End ist das Objektmodell selber hier eigentlich nicht sooo wichtig. ALOCOM hat halt modularisierte Komponenten und überprüft mit Hilfe von Post-Processing Techniken ob eine Komponente (Folie etc.), die in ALOCOM eingestellt werden soll, schon vorhanden ist: wenn ja wird eine partOf-Relation gezogen. Beim Einstellen einer Komponente werden ohnehin partOf-Relationen und Sequenz-Relationen (istVorgängerVon etc.) gezogen.
  • CAM kann auch in document-centric "umgerechnet" werden ist aber nicht sonderlich praktikabel
  • Lieber das nehmen.
  • Was ist mit Word?
  • Evtl. eher noch auf Spezifika von PowerPoint eingehen: Modulares Objektmodell, Rückverfolgbarkeit der Aktionen etc.
  • Der vierte Fall kommt in PPT so gut wie nicht vor.
  • PowerPoint-Handler: Copy/Paste from PPT to PPT HTML (HTML (z.B. Text) wird von einer Website kopiert) : Holt URL aus dem Clipboard Filesystem (ganze Files wie Bilder werden aus dem Dateisystem kopiert): Holt Pfade der Dateien aus dem Clipboard Window Heuristics (wenn aus beliebigen anderen Applikationen Inhalte kopiert werden oder Bilder oder inline pdf-Inhalte einer Website): Der Pfad bzw. die URL wird über den Fenstertitel und den Recent-Folder bzw. mit Hilfe von ScreenScraping gewonnen)
  • Hier kannst du auf jeden Fall sagen, dass die Anzahl der Wiederverwendungen als Faktor in das Lucene-Ranking eingehen. Dementsprechend öfter wiederverwendete Ressourcen höher gerankt werden bei der Suche.

    • Usage of information
  • Possible Approaches to get information
      • User interaction
        • System gets information from the user
        •  Work for the user
        • Users are usually lazy
        • Users' decisions can not be trusted generally
      • Post processing
        • Like data mining, content analysis, …
        •  Complicated
        •  Quite high effort (implementation and computation)
        •  Information can not be trusted 100%
      • Our approach: information capturing
        • Capture information when it occurs
        • Low computation effort
        • No work for the user
        • Information can be trusted (which have to be validated)

    • Usage of information
  • 1st Application Scenario: PowerPoint
    • PowerPoint presentations have high potential of being re-used
    • Re-Use information is not captured anywhere
    • … but would be helpful for retrieval and authoring:
        • How do documents (presentations) connect / relate?
        • Which slides are most popular for re-use?
        • Who is re-using / updating my presentation?
        • Where is the presentation I re-used slides from?
        • ...
    •  Try to capture re-use information in PowerPoint
        • Copy & Paste of slides, images etc.
        • Re-use of whole presentations
        • Editing and saving existing presentations
    ?
  • Information Captured in PowerPoint
    • Relations resulting from PowerPoint internal re-use of slides, shapes or text ( deliversElementTo / containsElementOf )
    • Relations resulting from external re-use of content from other documents (e.g. Word documents) or websites ( deliversElementTo / containsElementOf )
    • Relations resulting from re-use of media objects (like e.g. pictures), including "secondary relations" between two presentations (re-)using the same object ( isPartOf / contains )
    • Variant or identity relations connecting different presentation instances, e.g. when a presentation is saved under a different name or copied in the filesystem (isVariantOf / hasVariant)
  • Relation Information A' Has Variant Is Variant of Case 3: A O A Case 4: Links to Is linked from Link to O O A is Part of contains Case 1: A B O O Delivers Element to Contains Element of Case 2: O O
