Superimposed Information By Uma Murthy and Edward Fox Source: NSF/NSDL project proposal # 0405396 CS4624: Multimedia, Hypertext, and Information Access
Outline for Today • Presentation • Introduction, basic concepts • Demonstrations CS4624: Multimedia, Hypertext, and Information Access
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
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
SI Examples • Annotations • Bookmarks • Comments • Concept Maps • Concordances • Previews CS4624: Multimedia, Hypertext, and Information Access
Components of SI Architecture * Source: ICDE04 presentation by Murthy, et al. CS4624: Multimedia, Hypertext, and Information Access
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
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
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
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
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
