Issues of Information Semantics and Granularity in Cross-Media Publishing

Presentation given at CAiSE 2003, Conference on Advanced Information Systems Engineering, Klagenfurt/Velden, Austria.

ABSTRACT: While there have been dramatic increases in the use of digital technologies for the storage and processing of information, the affordances of paper have ensured its retention as a key information medium. Recent developments in digitally augmented paper provide the potential to embed active links within printed documents, thereby turning paper into an interactive medium. In this paper, we address the issues of information granularity and semantics that arise in integrating paper as a first-class interactive information medium in hypermedia systems and show that the information server is vital in realising the true potential of this vision. Further, we discuss the authoring issues of cross-media information environments and the forms of tools required to support the various categories of authoring activity.

2. Global Information Systems Group Department of Computer Science ETH Zurich, Switzerland Outline Motivation Integration of digital and printed information information granularity information semantics Architecture / information concepts for Digitally Augmented Paper Other aspects of cross-media publishing
3. Global Information Systems Group Department of Computer Science ETH Zurich, Switzerland The Myth of the Paperless Office For decades, people have predicted the office of the future as a paperless office documents generated, published and distributed electronically documents read electronically What has happened to this imminent revolution?

5. Global Information Systems Group Department of Computer Science ETH Zurich, Switzerland Case Study BBC Blue Planet series television series available on video/DVD book web site fact files quizzes games Open University course book and CD
6. Global Information Systems Group Department of Computer Science ETH Zurich, Switzerland Linking of Sections to Digital Resources symbols as link to video/CD note timing information to locate parts of video
7. Global Information Systems Group Department of Computer Science ETH Zurich, Switzerland Problems of Printed Information Coarse granularity of available links to digital media (symbols) sections of text linked to video/CD good to have finer units of granularity Missing link context in printed media impossible to resolve links back to printed paper (unidirectional linking)
8. Global Information Systems Group Department of Computer Science ETH Zurich, Switzerland Paper++ Document Encoding page number, x and y positions Use RFID tags (Radio Frequency Identification) for document identification Use inductive ink to print a grid of invisible position information on paper Information: (DocID, pageNo, x, y)
