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)

ReCap.KOM AddIns for PowerPoint and Word docendeo



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)
