  1. Superimposed Information By Uma Murthy and Edward Fox Source: NSF/NSDL project proposal # 0405396 CS4624: Multimedia, Hypertext, and Information Access

  2. Outline for Today • Presentation • Introduction, basic concepts • Demonstrations CS4624: Multimedia, Hypertext, and Information Access

  3. Background • SI concept and software developed by people at Portland State University, including • Lois M. Delcambre • David Maier • Sudarshan Murthy CS4624: Multimedia, Hypertext, and Information Access

  4. What is Superimposed Information (SI)? • New interpretation of existing information • Comments, new structures • Focuses on • Information at sub-document granularity • Information from heterogeneous sources • Working with information insitu CS4624: Multimedia, Hypertext, and Information Access

  5. SI Examples • Annotations • Bookmarks • Comments • Concept Maps • Concordances • Previews CS4624: Multimedia, Hypertext, and Information Access

  6. Components of SI Architecture * Source: ICDE04 presentation by Murthy, et al. CS4624: Multimedia, Hypertext, and Information Access

  7. What is a Mark? • An abstraction • Represents a selection of information inside a base layer • Includes address information • May be used to retrieve contextual information CS4624: Multimedia, Hypertext, and Information Access

  8. SI and Hypertext • Marks may be considered as a deeper (higher/lower) level abstraction of hypertext. • Marks represented as URIs CS4624: Multimedia, Hypertext, and Information Access

  9. Superimposed Applications • Sidepad • Concept mapping/note taking tool • SIMPEL • Multimedia presentation editor and player • Marks as URIs • Marks in HTML documents CS4624: Multimedia, Hypertext, and Information Access

  10. SIMPEL: A SuperImposed Multimedia Presentation Editor and pLayer • Select and reference multimedia information (text, audio, video) at varying granularity • Create a presentation - arrange selections (references) in a time-synchronized manner • “Play” presentation CS4624: Multimedia, Hypertext, and Information Access

  11. Demonstrations • Creating marks. • Using marks in an HTML document. • Using marks in a Sidepad document. • Creating and playing SIMPEL presentations. CS4624: Multimedia, Hypertext, and Information Access
