•  Vast amounts of cultural/scientific resources !digital available!

•  Still memory organisations (i.e. library, museums, archives) face challenges in disseminating their content.!

Challenge #1: Competition

•  Competition with easy consumable mainstream content

•  Highly commercialized•  No direct business model

Challenge #2: Consumption

•  Highly specialised content•  Unawareness of existing content and

portals•  User triggered search, not discovery•  Content is not contextualised

Concept

„Bring the content to the user, not the user to the content“

•  Inject cultural and scientific content into existing web channels!–  Websites (Wikipedia, etc.)!–  CMS/LMS!–  Social media channels !

(Twitter, etc.)!–  Blogging!

•  Personalise Long Tail content!–  Context of the web channel!–  User Context/User Profile!–  User Task!

4.4 Client Application for Content CreationIn the content creation scenario, additional cultural resources from the content providers are retrievedwhile users are creating their own (textual) content. To showcase this scenario, we implemented anadd-on for the online word processor Google Docs14. The core idea of the EEXCESS Google Docs add-on is to have a collaborative way of writing documents, and – while writing – a simple way to includerelated images and citations. Real-time online collaboration is available in Google Docs per se, theEEXCESS add-on extends Google Docs with EEXCESS results that can be inserted with one click.

The EEXCESS Google Docs add-on can be downloaded from the App-Store 15 and needs to be startedfor each document separately from the menu Add-ons ! E-Explorer ! Start. When activated, theadd-on is visible on the right side of the currently edited document (see Figure 7). To get results aphrase in the document can be highlighted (either by double clicking or keyboard selection) and isautomatically added to the search field. The add-on searches all connected content providers via thefederated aggregation component and displays the results as a list on the sidebar. The details of theresults can be accessed by clicking on the list entry. This brings you to a page with more detailedinformation about the digital object. Resources can be included in the document either as a referenceor an image (two icons on the right side of a result in Figure 7). The add-on has been evaluated with25 students of a seminar at the Munich School of Philosophy using a questionnaire. The questionnaire
