Using UML and XMI for Generating Adaptive Navigation Sequences in Web-Based Systems
[chapter]
2003
Lecture Notes in Computer Science
Preserved Fulltext
In this paper we discuss a method for modelling and generating adaptive navigation sequences from the UML state diagrams. The method is discussed on a case of adaptive e-course. ...
a prototyping of navigation support in adaptive web-based systems. ...
There are two possibilities of mappings from information model: (1) a superstate mapped to a class with substates mapped to class attributes, and (2) a superstate mapped to a class instance with substates ...

We present a robot navigation system that uses the same symbolic spatial information employed by humans to purposefully navigate in unseen built environments with a level of performance comparable to humans ...
The navigation system uses a novel data structure called the abstract map to imagine malleable spatial models for unseen spaces from spatial symbols. ...
RESULTS Symbolic navigation performance with the abstract map was evaluated against human participants, with a number of qualitative insights gained about the human symbolic navigation process. ...
