3. 4/13/2006CS4624: 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

4. 4/13/2006CS4624: 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

7. 4/13/2006CS4624: 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

8. 4/13/2006CS4624: 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
